Description

Technical Field

[0001] The present invention relates to the field of communications, and in particular to a method and device for obtaining a three-dimensional model of a lattice tower foundation. Background Art

[0002] A lattice tower is a common type of communication tower, primarily consisting of a tower body, lightning rod, ladder, platform, and antenna bracket. It is a tall structure designed to mount communication antennas. The tower body is typically constructed of section steel or steel pipes, connected by web members to form a monolithic, triangular or quadrilateral structure. The main member is also known as the tower column, and web members are generally categorized into crossbars, diagonal bars, diaphragms, and auxiliary components based on their structural characteristics. Lattice towers offer advantages such as reduced steel consumption, high overall rigidity, strong mounting capacity, and flexible installation. They are widely used in applications with large space, high tower height requirements, and poor hoisting conditions. The lattice tower foundation, which supports the tower, plays a significant role compared to the above-ground portion of the lattice tower. Existing lattice tower foundation modeling processes often fail to summarize and summarize the default modeling parameters and the interrelationships between its components, making parametric rapid modeling impossible.

[0028] Example 1

[0029] According to an embodiment of the present invention, an embodiment of a method for obtaining a three-dimensional model of a lattice tower foundation is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0030] Figure 1 A flowchart of a method for obtaining a three-dimensional model of a lattice tower foundation according to one embodiment of the present invention is shown. The method can be applied to a computer device. The three-dimensional model of the lattice tower foundation includes a display model and a calculation model of the corresponding lattice tower foundation. The method includes steps S101, S102, and S103. In step S101, foundation type information, basic information, calculation information, and geological survey information corresponding to a target lattice tower foundation are obtained. The basic information includes foundation shape information of the target lattice tower foundation, the calculation information includes calculation parameter information indicating the force details of the target lattice tower foundation, and the geological survey information includes soil layer parameter information indicating the location of the target lattice tower foundation. In step S102, a corresponding initial foundation model is determined based on the foundation type information of the target lattice tower foundation. In step S103, a display model of the target lattice tower foundation is established or updated based on the initial foundation model and the basic information. A calculation model of the target lattice tower foundation is established or updated based on the display model, calculation information, and geological survey information, thereby obtaining a three-dimensional model of the target lattice tower foundation. Computer devices include, but are not limited to, client devices, network devices, or devices formed by integrating client devices and network devices via a network. Client devices include, but are not limited to, any mobile electronic product capable of human-computer interaction with a client (e.g., via a touchpad), such as smartphones and tablets. Network devices include, but are not limited to, computers, network hosts, a single network server, a collection of multiple network servers, or a cloud consisting of multiple servers.

[0031] Specifically, in step S101, foundation type information, basic information, calculation information, and geological survey information corresponding to a target lattice tower foundation are obtained. The basic information includes the target lattice tower foundation's foundation shape information, the calculation information includes calculation parameter information indicating the force details of the target lattice tower foundation, and the geological survey information includes soil layer parameter information indicating the location of the target lattice tower foundation. For example, based on data requirements from a manager, a computer device obtains modeling data required for three-dimensional modeling of the target lattice tower foundation, such as the foundation type information, basic information, calculation information, and geological survey information corresponding to the target lattice tower foundation. Based on the obtained modeling data, the computer device obtains a display model and a calculation model of the target lattice tower foundation, thereby determining a three-dimensional model of the target lattice tower foundation. The display model is used to present the three-dimensional shape and structure of the target lattice tower foundation using specific software, while the calculation model is used to display force analysis and calculations performed based on the shape, structure, and materials of the target lattice tower foundation. The calculation model can be superimposed on the display model to determine an integrated three-dimensional model of the lattice tower foundation. The calculation model can also be displayed separately from the display model to determine an intuitive and specific three-dimensional model of the lattice tower foundation. The number of target lattice tower foundations can be one or more, and this is not limited herein. If there are multiple target lattice tower foundations, the modeling process corresponding to the following embodiments is performed on each target lattice tower foundation to obtain the three-dimensional models of the multiple target lattice tower foundations. The basic information of the target lattice tower foundation includes basic shape information used to describe the shape and structure of the target lattice tower foundation, such as the lattice tower cross-section, foundation root opening, distance from the connecting beam to the ground surface, connecting beam height, connecting beam width, burial depth, base plate thickness, foundation column width, base plate side length, and the size of the foundation column above the ground; the calculation information includes multiple calculation parameter information used to describe the stress conditions of the target lattice tower foundation, such as the standard value of the maximum pressure at the top of the column, the design value of the maximum pressure at the top of the column, the standard value of the shear force at the top of the column, the design value of the shear force at the top of the column, the design value of the maximum pullout force at the top of the column, the standard value of the maximum pullout force at the top of the column, the design value of the shear force at the top of the column, and the concrete density; the geological survey information includes soil layer parameter information used to indicate the location of the target lattice tower foundation, such as the groundwater level, soil layer number, soil layer name, soil layer depth, soil layer thickness, and soil layer density.

[0032] Here, based on different foundation type information, the corresponding basic information, calculation information, and geological survey information all vary. Specifically, in some embodiments, foundation type information includes, but is not limited to: independent foundation; raft foundation; single pile foundation; independent cap and multi-pile foundation; raft cap and multi-pile foundation. An independent foundation is an extended foundation used to support a single column of a conventional upper tower structure; a raft foundation is an extended foundation used to support the entire upper conventional tower structure (multiple columns); a single pile foundation is a foundation composed of a single pile (steel pipe pile or cast-in-place concrete pile) used to support a single column of a conventional upper tower structure; and a multi-pile foundation is a foundation composed of multiple piles (cast-in-place concrete piles or precast piles) and caps connected to the pile tops, used to support a single column or the entire upper conventional tower structure (multiple columns). A cap-slab multi-pile foundation comprises a foundation consisting of multiple piles (concrete cast-in-place piles or precast piles) and caps connected to the pile tops, used to support a single column or an entire column (multiple columns) of a conventional upper iron tower structure. When the cap supports a single column of a lattice tower, this type of foundation is called an independent cap-slab multi-pile foundation. When the cap supports the entire lattice tower (all columns), this type of foundation is called a raft cap-slab multi-pile foundation. Of course, those skilled in the art will appreciate that the above foundation type information is merely illustrative, and other existing or future foundation type information, if applicable to the present invention, should also be included within the scope of protection of the present invention and incorporated herein by reference. For certain foundation types of lattice tower foundations, there may be multiple sub-type information classifications. For example, an independent cap-slab multi-pile foundation includes foundation sub-type information such as concrete cast-in-place piles, precast square piles, and rock anchors. Similarly, a raft cap-slab multi-pile foundation includes foundation sub-type information such as concrete cast-in-place piles, precast square piles, and rock anchors.

[0033] Specifically, if the foundation type information of the lattice tower foundation includes an independent foundation, the corresponding basic information includes the cross section of the lattice tower, the foundation root opening, the distance from the connecting beam to the ground surface, the connecting beam height, the connecting beam width, the buried depth, the bottom plate thickness, the foundation column width, the bottom plate side length, and the size of the foundation column above the ground; the corresponding calculation information includes the standard value of the maximum pressure at the top of the column, the design value of the maximum pressure at the top of the column, the standard value of the shear force at the top of the column, the design value of the shear force at the top of the column, the design value of the maximum pullout force at the top of the column, the standard value of the maximum pullout force at the top of the column, the design value of the shear force at the top of the column, the concrete weight, the concrete strength grade, Rebar grade, distance from the bottom plate longitudinal reinforcement resultant point to the section edge, distance from the longitudinal reinforcement resultant point on one side of the foundation column to the section edge, corrected foundation bearing capacity characteristic value, critical depth calculated using the soil weight method, and soil uplift angle; corresponding geological survey information includes groundwater level, soil layer (rock) number, soil layer (rock) name, soil layer (rock) depth, soil layer (rock) thickness, soil layer density, soil compression modulus, foundation bearing capacity characteristic value of each soil layer, standard value of rock compressive strength, rock integrity (e.g., relatively broken rock, relatively intact rock, intact rock), etc. Herein, the soil layer referred to in this invention is used to indicate the soil layer parameters corresponding to each soil layer. For example, the soil layer (rock) number is used to indicate the number of each soil (rock) layer, and correspondingly, the soil layer (rock) depth is used to indicate the bottom elevation of each soil (rock) layer.

[0034] For example, if the foundation type information of the lattice tower foundation includes raft foundation, the corresponding basic information includes the cross section of the lattice tower, the foundation root opening, the distance from the coupling beam to the ground surface, the coupling beam height, the coupling beam width, the buried depth, the bottom plate thickness, the foundation column width, the size of the foundation column above the ground, the bottom plate side length, etc.; the corresponding calculation information includes the standard value of the foundation top pressure, the design value of the foundation top pressure, the standard value of the foundation top horizontal force, the design value of the foundation top horizontal force, the standard value of the foundation top bending moment, the design value of the foundation top bending moment, the design value of the column top maximum pressure, the design value of the column top shear force, the design value of the column top maximum pullout force, The design value of the shear force at the top of the column, the weight of concrete, the strength grade of concrete, the steel bar brand, the distance between the resultant force point of the bottom plate longitudinal reinforcement and the edge of the section, the distance between the resultant force point of the longitudinal reinforcement on one side of the foundation column and the edge of the section, the corrected characteristic value of the foundation bearing capacity, etc.; the corresponding geological survey information includes the groundwater level, the soil (rock) layer number, the soil (rock) layer name, the soil (rock) layer depth, the soil (rock) thickness, the soil layer weight, the compression modulus of each soil layer, the characteristic value of the foundation bearing capacity of each soil layer, the standard value of the rock compressive strength, and the degree of rock integrity (for example, relatively broken rock mass, relatively intact rock, intact rock), etc. If the foundation type information of the lattice tower foundation includes a concrete poured single pile foundation, the corresponding basic information includes whether a cap is set, the burial depth, the bottom plate thickness, the foundation column width, the bottom plate width, the bottom plate length, the size of the foundation column above the ground, the pile length, the pile diameter, whether the bottom is expanded, etc.; the corresponding calculation information includes the standard value of the foundation top pressure, the design value of the foundation top pressure, the standard value of the foundation top horizontal force, the design value of the foundation top horizontal force, the standard value of the foundation top bending moment, the design value of the foundation top bending moment, the concrete strength grade, the radius of the circle where the longitudinal reinforcement is located, The cross-sectional area of ​​all longitudinal reinforcements of the foundation pile, the pile-forming process coefficient, the bottom diameter of the expanded-bottom pile, the variable cross-section and slope height of the wide-bottom pile, the comprehensive coefficient of the rock-embedded section, etc.; the corresponding geological survey information includes the groundwater level elevation, soil layer (rock) number, soil layer (rock) name, soil layer (rock) depth, soil layer (rock) thickness, soil layer density, soil layer m-value, soil type (divided into fill, clay, silt, sand, gravel), cast-in-place pile side friction resistance (pile side friction resistance of each soil layer), cast-in-place pile end resistance (pile end resistance of each soil layer), standard value of rock compressive strength, etc. It should be noted that the soil layer m-value refers to the proportional coefficient of the soil layer horizontal resistance coefficient, which is a parameter in soil mechanics used to quantify the ability of the soil layer to resist external forces in the horizontal direction. Its unit is MN / m 4 (or equivalent units). This parameter plays an important role in foundation engineering, pile foundation design and basement structure analysis, and directly affects the lateral restraint stiffness of the soil on the structure.

[0035] For example, if the foundation type information of the lattice tower foundation includes a single pile foundation, the corresponding basic information includes the cross section of the lattice tower, the foundation root opening, the distance from the connecting beam to the ground surface, the connecting beam height, the connecting beam width, whether a bearing platform is set, the burial depth, the bottom plate thickness, the foundation column width, the bottom plate side length, the size of the foundation column above the ground, the size of the pile top above the ground, the pile length, the pile diameter, whether the bottom is expanded, etc.; the corresponding calculation information includes the standard value of the maximum pressure on the pile top, the design value of the maximum pressure on the pile top, the standard value of the maximum pullout force on the pile top, the design value of the maximum pullout force on the pile top, the concrete weight, the concrete strength grade, the steel bar brand, and the cross-sectional area of ​​all longitudinal steel bars of the foundation pile. The corresponding geological survey information includes groundwater level, soil (rock) layer number, soil (rock) layer name, soil (rock) layer depth, soil (rock) layer thickness, soil layer density, soil type (e.g., fill, clay, silt, sand, gravel), lateral friction of precast piles / tubular piles, end resistance of precast piles / tubular piles, lateral friction of cast-in-place piles, end resistance of cast-in-place piles, pull-out coefficient, and standard value of rock compressive strength.

[0036] For example, if the foundation type information of the lattice tower foundation includes an independent pedestal multi-pile foundation, the corresponding basic information includes the lattice tower cross section, foundation root opening, distance from the coupling beam to the ground plane, coupling beam height, coupling beam width, burial depth, bottom plate thickness, foundation column width, bottom plate side length, foundation column height above the ground, pile type (for example, concrete cast-in-place piles, prefabricated square piles, rock anchors), pile length (pile length corresponding to each pile type), pile size, number of pile rows, number of pile columns, pile horizontal margin (horizontal distance from the center of the outermost pile to the pedestal edge) and pile vertical margin (vertical distance from the center of the outermost pile to the pedestal edge), etc.; the corresponding calculation information includes the standard value of foundation top pressure, design value of foundation top pressure, standard value of foundation top horizontal force, design value of foundation top horizontal force, standard value of foundation top bending moment, foundation top Design value of bending moment, concrete density, concrete strength grade, steel bar brand, cross-sectional area of ​​all longitudinal reinforcements in foundation piles, distance from the resultant force point of the bottom plate longitudinal reinforcement to the edge of the cross-sectional area, pile construction process coefficient, and comprehensive coefficient of the rock-embedded section (related to the depth-to-diameter ratio of the rock-embedded section, rock hardness, and pile construction process); corresponding geological survey information includes groundwater level, soil (rock) layer number, soil (rock) layer name, soil (rock) layer depth, soil (rock) layer thickness, soil layer density, soil type, lateral friction of precast piles / tubular piles, pile end resistance of precast piles / tubular piles, lateral friction of cast-in-place piles, pile end resistance of cast-in-place piles, pull-out coefficient, bond strength (standard value of the ultimate bond strength between rock and anchor body), rock hardness (soft rock, relatively soft rock, hard rock, used for estimation when bond strength parameters are lacking in local survey), and standard value of rock compressive strength.

[0037] For example, if the foundation type information of the lattice tower foundation includes raft slab cap multi-pile foundation, the corresponding basic information includes the lattice tower cross section, foundation root opening, whether to set a connecting beam, the distance from the connecting beam to the ground plane, the connecting beam height, the connecting beam width, the buried depth, the bottom plate thickness, the foundation column width, the bottom plate side length, the size of the foundation column above the ground, the pile type (for example, concrete cast-in-place piles, prefabricated square piles, rock anchors), the pile length (the pile length corresponding to each pile type), the pile size, the number of pile rows, the number of pile columns, the pile horizontal margin (the horizontal distance from the center of the outermost pile to the cap edge) and the pile vertical margin (the vertical distance from the center of the outermost pile to the cap edge), etc.; the corresponding calculation information includes the standard value of foundation top pressure, the design value of foundation top pressure, the standard value of foundation top horizontal force, the design value of foundation top horizontal force, the standard value of foundation top bending moment, the foundation The design value of the bending moment at the top of the foundation, the density of concrete, the concrete strength grade, the steel bar brand, the cross-sectional area of ​​all longitudinal steel bars of the foundation pile, the distance between the resultant force point of the bottom plate longitudinal bars and the edge of the cross-sectional area, the pile construction process coefficient, and the comprehensive coefficient of the rock-embedded section (related to the depth-to-diameter ratio of the rock-embedded section, the hardness of the rock, and the pile construction process); the corresponding geological survey information includes the groundwater level, the soil (rock) layer number, the soil (rock) layer name, the soil (rock) layer depth, the soil (rock) layer thickness, the soil layer density, the soil type, the lateral friction of precast piles and tubular piles, the pile end resistance of precast piles and tubular piles, the lateral friction of cast-in-place piles, the pile end resistance of cast-in-place piles, the pull-out coefficient, the bond strength (the standard value of the ultimate bond strength between rock and anchor body), the rock hardness (soft rock, relatively soft rock, hard rock, used for estimation when the bond strength parameters are lacking in the local survey), and the standard value of the rock compressive strength.

[0038] Of course, those skilled in the art should understand that the above basic information, calculation information and geological survey information are only examples. Other existing or future basic information, calculation information and geological survey information, if applicable to the present invention, should also be included in the scope of protection of the present invention and are included here by reference.

[0039] For the aforementioned modeling data, the unit for items related to component size is mm, and the unit for elevation is m. When using relative elevation, ±0.000 is used as the coordinate point of the coordinate origin on the Z axis; the coordinate system is determined according to the right-hand rule, and the Cartesian rectangular coordinate system should be selected. At the same time, the tower height direction of the conventional iron tower is set as the positive direction of the coordinate system Z axis. The modeling data may be the relevant parameters from the design drawings and / or inspection reports input by the user regarding the lattice tower foundation. The number of target lattice tower foundations may be one or more. In other words, the acquisition of the three-dimensional model of the target lattice tower foundation may be the individual acquisition of a single lattice tower foundation or the batch acquisition of multiple lattice towers, etc., which is not limited here.

[0040] In step S102, a corresponding initial foundation model is determined based on the foundation type information of the target lattice tower foundation. For example, after receiving the input modeling data, the computer device may establish a corresponding display model and calculation model based on the modeling data. Before determining the display model, the computer device first determines a corresponding initial foundation model based on the foundation type information, thereby inputting the basic information of the target lattice tower foundation into the initial foundation model to generate a display model of the target lattice tower foundation. The initial foundation model is used to indicate the basic model and modeling rules of the corresponding basic model of the physical structure of the target lattice tower foundation corresponding to the foundation type information, such as the tower foot flange model, foundation cap model, foundation cushion model, foundation envelope model, and / or foundation pile model. Initial modules of different shapes and structures can be set according to different needs.

[0041] Specifically, if the foundation type information of the lattice tower foundation includes an independent foundation, the corresponding foundation initial model includes a foundation pedestal model, a foundation cushion model, and a foundation encapsulation model, among which the foundation pedestal outline dimensions: foundation root opening, foundation bottom plate size, and foundation column size need to be modeled at a 1:1 ratio, with the length unit being "millimeter (mm)", the height of the foundation encapsulation model is modeled at 300mm, and the foundation cushion model is modeled with a 100mm expansion of the foundation bottom plate and a thickness of 100mm; in some cases, the foundation initial model of the independent foundation also includes a connecting beam model, the height of the connecting beam model can be modeled at 1 / 10 of the root opening, and the width can be modeled at half the height of the connecting beam, etc. If the foundation type information for a lattice tower foundation includes a raft foundation, the corresponding initial foundation model includes the raft model, the foundation cushion model, and the foundation envelope model. The raft outline dimensions, including the raft dimensions, foundation column dimensions, and foundation root opening, must be modeled at a 1:1 scale, with lengths in millimeters (mm). The foundation envelope model is modeled with a height of 300mm, and the foundation cushion model is modeled with a 100mm extension of the foundation base plate and a thickness of 100mm. In some cases, the raft model's initial foundation model may also include a coupling beam, in which case a 3D model of the coupling beam will be displayed. If the foundation type information for a lattice tower foundation includes a steel pipe pile foundation, the corresponding initial foundation model includes the tower foot flange model and the foundation steel pipe model. The foundation diameter and pile length of the steel pipe model must be modeled at a 1:1 scale, with lengths in millimeters (mm). The thickness of the steel pipe model is fixed at 20mm. If the foundation type information for a lattice tower foundation includes a single pile foundation, the corresponding initial foundation model includes a foundation cap model and a foundation envelope model. The cap base plate dimensions, foundation column dimensions, cast-in-place pile diameter, and pile length of the foundation cap model must be modeled at a 1:1 scale, with lengths in millimeters. The foundation envelope model is modeled as 300 mm high. When a cap is set, the model should include a cap cushion model. The cushion is modeled as 100 mm thick, extending 100 mm from the cap base plate. If the foundation type information for a lattice tower foundation includes an independent cap multi-pile foundation, the corresponding initial foundation model includes a foundation cap model, a foundation cushion model, a foundation envelope model, and models of multiple foundation piles. The foundation cap outline dimensions, including cap base plate dimensions, foundation column dimensions, pile dimensions, pile length, and pile layout, must be modeled at a 1:1 scale, with lengths in millimeters. The foundation envelope model is modeled as 300 mm high, and the foundation cushion model is modeled as 100 mm thick, extending 100 mm from the base plate. In some cases, the initial foundation model of an independent cap multi-pile foundation should also include connecting beam information, and the multiple foundation pile models include but are not limited to at least one of concrete cast-in-place piles, prefabricated square piles, and rock anchors.If the foundation type information for a lattice tower foundation includes a raft cap multi-pile foundation, the corresponding initial foundation model includes a foundation raft model, a foundation cushion model, a foundation envelope model, and corresponding multiple foundation pile models. The foundation raft outline dimensions, including raft dimensions, foundation column dimensions, pile dimensions, pile length, and pile layout information, must be modeled at a 1:1 scale, with lengths expressed in millimeters (mm). The foundation envelope model is modeled with a height of 300 mm, and the foundation cushion model is modeled with a 100 mm expansion of the foundation base plate and a thickness of 100 mm. In some cases, the initial foundation model for a raft cap multi-pile foundation should also include coupling beam information. The multiple foundation pile models include, but are not limited to, at least one of cast-in-place concrete piles, precast square piles, and rock anchors. Those skilled in the art will appreciate that the above modeling rules are merely examples, and that other existing or future modeling rules, if applicable to the present invention, are also encompassed within the scope of the present invention and are incorporated herein by reference.

[0042] In step S103, a display model of the target lattice tower foundation is established or updated based on the initial foundation model and basic information. A calculation model of the target lattice tower foundation is established or updated based on the display model, calculation information, and geological survey information to obtain a three-dimensional model of the target lattice tower foundation. For example, after obtaining the initial foundation model of the target lattice tower foundation, the computer device adjusts the initial foundation model based on model parameters in the basic information of the target lattice tower foundation to obtain a three-dimensional display model of the target lattice tower foundation. Based on the display model, the computer device can combine the calculation information and geological survey information to model the stress conditions of the target lattice tower foundation to obtain a corresponding calculation model. For example, the computer device determines the corresponding calculation model based on the structure of the target lattice tower foundation in the display model and calculation model parameters (parameters that can be used for calculations included in the calculation information and geological survey information). The calculation model can be used to calculate the load-bearing state information of the target lattice tower foundation. The load-bearing state information is used to indicate the pull-out resistance, compression resistance, overturning resistance, and load-bearing capacity analysis of various structures in the target lattice tower foundation.

[0043] To facilitate data analysis and management, the computer device stores the acquired display model and calculation model of the target lattice tower foundation in a database. In some embodiments, the method further includes step S104 (not shown), in which foundation identification information and foundation location information of the target lattice tower foundation are acquired. Target foundation record information of the target lattice tower foundation is determined based on the foundation identification information, foundation location information, and the three-dimensional model. A corresponding lattice tower foundation modeling system is established or updated based on the target foundation record information. The lattice tower foundation modeling system includes one or more lattice tower foundation record information. For example, while acquiring the modeling data of the target lattice tower foundation, the computer device may also acquire foundation identification information and foundation location information of the target lattice tower foundation. The foundation identification information is used to uniquely identify the lattice tower foundation, such as a sequential number, a serial number, or a code based on preset rules. The foundation location information is used to locate the spatial position of the lattice tower foundation, such as latitude and longitude, or an electronic map location. The computer device can generate lattice tower foundation record information regarding the target lattice tower foundation based on the foundation identification information, foundation location information, and corresponding three-dimensional model of the target lattice tower foundation, and then enter the lattice tower foundation record information into a corresponding lattice tower foundation modeling system. The lattice tower foundation modeling system is used to model multiple lattice tower foundations and implement information entry, thereby facilitating querying and managing the multiple lattice tower foundations. In some embodiments, the computer device can also obtain load status information of the target lattice tower foundation and determine whether to enter the target lattice tower foundation into the system based on whether the load status information meets preset requirements, such as whether the current load coefficient is less than or equal to a preset coefficient threshold, or whether the load capacity indicator of the target lattice tower foundation has a margin or is fully loaded. For target lattice tower foundations that exceed the limit, parameters need to be modified and the corresponding information re-entered. When the computer device enters the information of the target lattice tower foundation, the lattice tower foundation record information is added to the load status information and entered into the lattice tower foundation modeling system for subsequent data verification.

[0044] In some embodiments, the method further includes step S105 (not shown). In step S105, if a user-side display operation regarding target foundation record information of a target lattice tower foundation is obtained, a three-dimensional model of the target lattice tower foundation is presented. For example, based on the user-side display operation regarding target foundation record information (e.g., a click or selection to view), the computer device may present the three-dimensional model of the target lattice tower foundation on a corresponding page. For example, the computer device may present the three-dimensional model of the target lattice tower foundation on a viewing page of the target lattice tower foundation by clicking on the page. In some cases, the corresponding lattice tower foundation record information includes the basic location information of the target lattice tower foundation. Based on the calling operation of the user terminal (for example, the user terminal calls based on the lattice tower foundation name or serial number, or calls based on part or all lattice tower foundation data in a certain area, etc.), the computer device can retrieve the basic location of one or more lattice tower foundations, and present the basic identification information of each lattice tower foundation on the map based on the basic location. Specifically, when the calling request includes the lattice tower foundation identification of the target lattice tower foundation, the basic identification information of the target lattice tower foundation is presented on the electronic map based on the basic location information of the target lattice tower foundation, and the three-dimensional model of the target lattice tower foundation is presented in the form of annotations, etc., wherein the computer device can convert the stored latitude and longitude to obtain the corresponding map coordinates, and present the basic identification information of the target lattice tower foundation at the corresponding position of the map coordinates.

[0045] In some embodiments, the method further includes step S106 (not shown). In step S106, if a modification operation on the presented 3D model is detected by the user, corresponding parameter modification information is determined based on the modification operation, and the model parameter information of the 3D model of the target lattice tower foundation is adjusted based on the parameter modification information. For example, the modification operation can be a parameter modification performed directly by the management user on a parameter page, or a modification operation on a component / shape of the model on the 3D model. Specifically, the computer device can present a three-dimensional model of the target lattice tower foundation to the user terminal through a corresponding display device. Accordingly, the presentation page includes a setting control for modifying the lattice tower foundation parameters. When a touch operation on the parameter modification control is obtained from the user terminal, the computer device can directly obtain corresponding parameter modification information based on the direct modification of the parameter by the touch operation. Alternatively, a corresponding model modification control is also included in the three-dimensional view presentation page corresponding to the corresponding three-dimensional model. The user terminal can modify the view of the three-dimensional model by directly modifying the model through touch, such as deleting, modifying, or adding a foundation component, or modifying the height of the pedestal. The computer device can calculate the corresponding parameter modification information based on the modification on the three-dimensional model by the user terminal, and adjust the model parameter information of the stored three-dimensional model based on the parameter modification information. After the computer device obtains the corresponding modification operation, it adjusts and synchronizes the parameter modification information corresponding to the modification operation to the lattice tower foundation record information of the target lattice tower foundation and to the local database. At the same time, the three-dimensional model of the target lattice tower foundation is further updated to be adjusted to the three-dimensional model after the operation, and the original bearing state information is adjusted to the modified bearing state information.

[0046] In some embodiments, the method further includes step S107 (not shown). In step S107, a query request regarding foundation distribution information and / or foundation load distribution information of lattice tower foundations is obtained, wherein the query request includes a target area to be queried. In response to the query request, the foundation distribution information and foundation load distribution information corresponding to the lattice tower foundations in the target area are presented in the lattice tower foundation modeling system. For example, the foundation distribution information indicates the number / proportion of lattice tower foundations based on specific factors (e.g., geographic location, foundation type information, etc.) among multiple lattice tower foundations stored in the lattice tower foundation modeling system. The foundation load capacity distribution information indicates the number or proportion of multiple lattice tower foundations recorded for each load status (e.g., fully loaded, with surplus capacity, overloaded, etc.). The multiple lattice tower foundations may include all lattice tower foundations in the lattice tower foundation modeling system, or may be selected from all lattice tower foundations, such as those selected based on a circled area or foundation type information, or selected by a management user, without limitation herein. For example, the bearing capacity of lattice tower foundations in a certain city, A, is as follows: 20% fully loaded, 20% with surplus capacity, and 60% exceeding the limit. The aforementioned statistical data can be used to intuitively display the foundation distribution information and / or bearing distribution information of the currently entered lattice tower foundations to the user terminal. When the number of entered lattice tower foundations is sufficient and the range is wide enough, this data is generally used to indicate the total bearing distribution information of all lattice tower foundations nationwide. Of course, when there are a sufficient number of entered lattice tower foundations, it is sometimes necessary to perform statistical analysis on the corresponding lattice tower foundation data in a specified target area (e.g., a certain city or a calibrated target area) to determine and present the bearing distribution information and foundation distribution information of the lattice tower foundations in the corresponding area. In some cases, the computer device can also display a trend chart of the changes in the number of entered lattice tower foundations in a certain city over a unit time period (e.g., one month, one year, or three years), or display the number of entered lattice tower foundations in each district branch, etc.

[0047] In some embodiments, the method further includes step S108 (not shown). In step S108, a bearing capacity coefficient of the target lattice tower foundation is determined based on the display model, the calculation model, the calculation information, and the geological survey information. Bearing status information of the target lattice tower is determined based on the bearing capacity coefficient, where the bearing status information includes overloaded, fully loaded, or with surplus capacity. For example, the computer device can calculate the bearing status information of the lattice tower foundation using the aforementioned parameters and the calculation model, such as calculating one or more status parameters such as foundation bearing capacity, foundation strength, single pile bearing capacity, and foundation stability. Based on the calculated results, the bearing status information of the lattice tower foundation is determined, such as whether the foundation is overloaded, fully loaded, or has surplus capacity. The aforementioned status parameters vary based on the foundation type information of the target lattice tower foundation. For example, for an independent foundation, only status parameters related to foundation bearing capacity and foundation strength need to be determined, while for a single pile foundation, the corresponding bearing status information needs to be determined based on status parameters such as foundation strength and single pile bearing capacity. In some cases, each of the aforementioned state parameters, such as foundation bearing capacity, foundation strength, single pile bearing capacity, and foundation stability, is characterized by one or more calculation coefficients. For example, foundation bearing capacity includes at least one of the foundation bearing coefficient, base detachment area coefficient, and weak underlying stratum bearing coefficient; foundation strength includes at least one of the bottom plate bending bearing coefficient, bottom plate shear resistance, column bearing coefficient, and pile body bearing coefficient; single pile bearing capacity includes at least one of the single pile foundation pile top horizontal displacement coefficient, single pile foundation rotation angle, single pile vertical compressive bearing coefficient, and single pile vertical pullout bearing coefficient; foundation stability includes at least one of the foundation pullout coefficient, foundation anti-overturning coefficient, and foundation anti-slip coefficient. The aforementioned state parameters are merely examples. Different lattice tower foundations with different foundation types require different state parameters to be calculated. The bearing state information of corresponding lattice tower foundations is analyzed and obtained based on different structures and types. Lattice tower foundations with different foundation types also have different calculation requirements for multiple calculation coefficients in the same state parameter. The computer device determines the corresponding three-dimensional model and the bearing state information of the lattice tower foundation, and simultaneously enters the three-dimensional model and the bearing state information corresponding to the three-dimensional model into the lattice tower foundation modeling system.

[0048] In some embodiments, determining the bearing state information of the target lattice tower based on the bearing capacity coefficient includes: if the bearing capacity coefficient is greater than 100%, determining the bearing state information of the target lattice tower as overloaded; if the bearing capacity coefficient is less than or equal to 100% and greater than a preset coefficient threshold, determining the bearing state information of the target lattice tower as fully loaded; and if the bearing capacity coefficient is less than or equal to the preset coefficient threshold, determining the bearing state information of the target lattice tower as having margin. For example, after obtaining the calculation coefficients included in the corresponding one or more state parameters, the computer device determines the bearing state information of the lattice tower foundation based on the multiple calculation coefficients, and compares the bearing state information of the target lattice tower foundation with the preset coefficient threshold to determine the bearing state information of the target lattice tower foundation. If the bearing state information is greater than a first preset coefficient threshold, determining the bearing state information as overloaded; if the bearing state information is less than or equal to the first preset coefficient threshold and greater than a second preset coefficient threshold, determining the bearing state information as having margin, etc. Specifically, in order to more intuitively reflect whether the load exceeds the limit, the first preset coefficient threshold is usually set to 100%. Then, when the load capacity coefficient is greater than 100%, the load status information of the target lattice tower foundation is determined to be exceeded; if the load capacity coefficient is less than or equal to 100% and greater than the preset coefficient threshold (for example, 95%, 80%, etc.), the load status information of the target lattice tower foundation is determined to be fully loaded; if the load capacity coefficient is less than or equal to the preset coefficient threshold, the load status information of the target lattice tower foundation is determined to have a margin.

[0049] In some embodiments, determining the bearing capacity coefficient of a target lattice tower foundation based on the display model, the calculation model, the calculation information, and the geological survey information includes calculating multiple calculation coefficients for the target lattice tower foundation based on the display model, the calculation model, the calculation information, and the geological survey information, and selecting the largest value among the multiple calculation coefficients (e.g., the corresponding calculation coefficient is determined by the ratio of a control parameter of the corresponding calculation coefficient to a control parameter limit) as the bearing capacity coefficient of the target lattice tower foundation. For example, after obtaining the calculation coefficients included in one or more corresponding state parameters, the computer device determines the bearing capacity coefficient of the lattice tower foundation based on the multiple calculation coefficients, such as by taking the average or median of the multiple calculation coefficients to determine the bearing capacity coefficient of the target lattice tower foundation. In some cases, considering the adverse effects of over-limit conditions on the lattice tower foundation during actual use, the computer device selects the largest value among the multiple calculation coefficients as the bearing capacity coefficient of the target lattice tower foundation, thereby determining the bearing state information of the target lattice tower foundation based on matching the bearing capacity coefficient with preset conditions.

[0050] Here, for lattice tower foundations with different foundation type information, it is generally necessary to comprehensively consider their bearing state information by referring to different coefficients in different state parameters. For example, in some embodiments, the foundation type information includes an independent foundation; wherein the calculation coefficients include the foundation bearing coefficient and the foundation pull-out stability coefficient. For example, the foundation bearing coefficient is determined by calculating the ratio of the corresponding foundation bearing control parameter to the parameter limit of the foundation bearing control parameter (e.g., a value of 1.0), wherein the foundation bearing control parameter is determined by the larger value of the axial load ratio and the eccentric load ratio, that is:

[0051] (1)

[0052] Where, is the foundation bearing control parameter, The average pressure on the bottom surface of the foundation corresponding to the standard combination of actions (kPa); is the corrected characteristic value of foundation bearing capacity; The maximum pressure value (kPa) at the edge of the bottom surface of the foundation when it is the standard combination corresponding to the action. It should be noted that the standard combination corresponding to the action refers to the combination method using standard values ​​or combination values ​​as the load representative values ​​during the design and calculation process, and this combination method is based on industry specifications, general standards or widely recognized best practices to ensure that the structure can meet the specified functional requirements under the normal use limit state. Among them,

[0053] 1) When the foundation bears axial load, the foundation bottom pressure can be calculated as follows:

[0054] (2)

[0055] Where, The vertical force value (kN) transmitted from the superstructure to the foundation when the standard combination of actions is corresponding; is the standard value of the foundation weight and the weight of the soil on the foundation (kN); A is the bottom surface area of ​​the foundation (m 2 ).in, =Concrete density (weighted average considering water level) × concrete volume + soil density (weighted average considering water level) × soil volume.

[0056] 2) When the foundation is subjected to a unidirectional eccentric load, the pressure on the bottom surface of the foundation is calculated as follows:

[0057] Where M k When the standard combination of actions is corresponding, the moment transmitted from the superstructure to the bottom of the foundation (kN·m); W is the resistance moment of the bottom of the foundation (m 3 );p kmin The minimum pressure (kPa) at the edge of the foundation bottom surface corresponding to the standard combination of actions.

[0058] If p kmin ≥0, then:

[0059] If p kmin <0, reference Figure 2 ( Figure 2 shows the base pressure when the bottom surface of the foundation is partially disengaged under a unidirectional eccentric load according to one embodiment of the present invention), then:

[0060] (6)

[0061] (7)

[0062] Where a is the distance from the point of action of the resultant force to the edge of the maximum pressure on the bottom surface of the foundation, l is Figure 2 The length of the base bottom surface parallel to the y-axis is shown in , b is the length of the base bottom surface in the direction of the moment, and e is the eccentricity.

[0063] 3) When the foundation is subjected to bi-directional eccentric loads, refer to Figure 3 ( Figure 3 1 shows the base pressure when the bottom surface of the foundation is partially disengaged under bidirectional eccentric load according to one embodiment of the present invention). The base pressure can be calculated as follows:

[0064] (8)

[0065] Where M kx 、M ky are the torque values ​​(kN·m) on the x and y axes transmitted from the superstructure to the bottom surface of the foundation when the standard combination of actions is corresponding; W x 、W y are the resistance moments of the foundation bottom surface on the x and y axes (m 3 ).

[0066] If p kmin ≥0, then:

[0067] (9)

[0068] If p kmin <0, then:

[0069] (11)

[0070] (12)

[0071] (13)

[0072] (14)

[0073] Among them, a x From the point of action of the resultant force to e x Distance from one side of the foundation edge, a y From the point of action of the resultant force to e y Distance from the foundation edge on one side, e x is the eccentricity in the x direction, e y is the eccentricity in the y direction, l is Figure 3 The length of the foundation bottom surface parallel to the y-axis is shown in . Based on the above process, the foundation bearing coefficient of the independent foundation can be obtained. Here, for the independent foundation of the lattice tower, the corresponding foundation bearing coefficient is calculated according to the axial load case. For the lattice tower raft foundation, etc., the corresponding foundation bearing coefficient can be calculated according to the axial load, unidirectional eccentric load, or bidirectional eccentric load case, depending on the specific situation.

[0074] For example, the basic pullout stability coefficient is determined by calculating the ratio of the corresponding basic pullout stability control parameter to the parameter limit value (e.g., 1.0) of the basic pullout stability control parameter, wherein the basic pullout stability control parameter is determined as follows:

[0075] (15)

[0076] Where, is the maximum pull-out force of the lattice tower independent foundation; G e The weight of the soil is calculated according to Article 7.4.3 and Appendix J of the Design Standard for Tall Structures GB50135-2019; As the basic weight, the =Concrete weight (weighted average considering water level) × concrete volume.

[0077] In some cases, in addition to the aforementioned essential factors, some non-essential factors for auxiliary reference are also included. For example, in some embodiments, the calculation coefficient also includes at least one of the bottom plate bending bearing coefficient, the weak underlying layer bearing coefficient, the bottom plate punching resistance coefficient, and the column bearing coefficient. For example, here, Figure 4 The load calculation of the extended foundation according to one embodiment of the present invention is shown as follows. Figure 4 As shown, under the action of axial load or unidirectional eccentric load, the bending moment of the intersection section between the foundation column and the base plate in two directions is calculated respectively, and the base plate bending bearing coefficient is calculated according to Formula 8.2.12 of the "Code for Design of Building Foundations" GB50007-2011, and the minimum reinforcement ratio requirements must be met:

[0078] (16)

[0079] Where M is the design value of the bending moment borne by the foundation slab, and As is the reinforcement area (mm 2), 0.9 is a fixed parameter, fy is the design value of the tensile strength of the steel bar (N / mm 2 ), h0 is the effective height of the foundation section, which refers to the distance from the outer edge of the compression zone of the section to the center of gravity of the resultant force of the tensile reinforcement.

[0080] In addition, calculate any cross section When the internal force is large, the design value of the uniformly distributed load on the base p0 can be obtained by the following formula:

[0081] p0= (17)

[0082] Where p0 is the uniformly distributed load on the base (kPa), p max is the maximum pressure on the base edge caused by the internal force on the top surface of the foundation (kPa), p x It is the base pressure (kPa) at the calculation section formed by the internal force transmitted from the top surface of the foundation.

[0083] In some cases, it is also necessary to calculate the top surface reinforcement. When the foundation is subjected to pullout force, the bottom plate pullout strength calculation should be carried out. According to the calculation, negative bending moment reinforcement should be placed on the top surface of the bottom plate, and the minimum reinforcement ratio requirements should be met. The design value of the uniformly distributed load on the foundation surface, p1, can be obtained by the following formula:

[0084] p1= (18)

[0085] Where G is the weight of the foundation and the weight of the covering soil within the range of the anti-uplift angle considering the partial coefficient of action. The anti-uplift angle should be adopted in accordance with Article 7.4.3 of the "Design Standard for Tall Structures" GB50135-2019; A is the area of ​​the foundation slab (m 2 ). When the foundation is subjected to pullout, both the bottom and top surfaces are considered simultaneously, and an unfavorable bending load coefficient is taken. For lattice towers, both the bottom and top surfaces must basically be considered simultaneously.

[0086] Here, when there is a weak underlying layer within the acceptance range of the foundation, the bearing coefficient of the weak underlying layer should be calculated in accordance with relevant regulations. The control parameter of the weak underlying layer coefficient is determined by the following formula:

[0087] (19)

[0088] Among them, p z When the standard combination of actions corresponds to the additional pressure value at the top surface of the weak underlying layer, the diffusion angle obtained by looking up the table based on the compression modulus ratio can be calculated; c is the self-weight pressure value of the soil at the bottom of the foundation. Specifically, p c = weight of soil above the foundation bottom (weighted average considering water level) × soil thickness; p cz is the self-weight pressure of the soil at the top of the weak underlying layer, pcz = soil density above the top of the weak underlying layer (weighted average considering water level) × soil thickness; f az is the characteristic value of the foundation bearing capacity at the top of the weak underlying layer after depth correction, f az =f ak + depth correction factor × soil density above the top of the weak underlying layer (weighted average considering the water level) × (soil thickness - 0.5). z 、p c According to the above p k (The average pressure value at the bottom of the foundation corresponding to the standard combination of actions) is calculated.

[0089] For independent foundations, when the shear failure cone falls within the foundation bottom surface, the punching shear coefficient of the base plate at the intersection of the column and foundation should be verified according to Article 8.2.8 of the "Code for Design of Building Foundations" GB50007-2011. For multi-pile foundations, the corresponding base plate punching shear coefficient should be calculated according to Articles 5.9.7 / 5.9.8 of the "Technical Code for Building Pile Foundations" JGJ94-2008.

[0090] The foundation columns shall be designed as eccentrically tensile or compressive reinforced concrete components, ignoring the embedding effect of the side backfill soil. The column bearing coefficient shall be verified in accordance with the relevant provisions of Section 6.2 of the "Standard for Design of Concrete Structures" GB / T 50010-2010.

[0091] In some embodiments, the foundation type information includes a raft foundation; the calculated coefficients include a foundation bearing coefficient and a base detached area coefficient. For example, the foundation bearing coefficient of a raft foundation is obtained in the same or similar manner as the foundation bearing coefficient of the aforementioned independent foundation. For another example, the base detached area coefficient is determined by calculating the ratio of a corresponding base detached area control parameter to a parameter limit (e.g., 1.0) of the base detached area control parameter, where the foundation bearing control parameter is determined by the following formula:

[0092] (20)

[0093] Where, are the foundation bearing control parameters, where a, b, a x 、a y Determined by the previous equations (6)-(14).

[0094] In some embodiments, the calculation coefficients also include at least one of the bottom plate bending bearing coefficient, the weak underlying layer bearing coefficient, the bottom plate punching shear coefficient, and the column bearing coefficient. The calculation method for the bottom plate bending bearing coefficient, the weak underlying layer bearing coefficient, the bottom plate punching shear coefficient, and the column bearing coefficient of the raft foundation is the same or similar to the method for obtaining the bottom plate bending bearing coefficient, the weak underlying layer bearing coefficient, the bottom plate punching shear coefficient, and the column bearing coefficient of the aforementioned independent foundation. Specifically, for example, the calculation of the punching shear coefficient and the bending bearing coefficient of the raft foundation bottom plate should be carried out in accordance with the current standard "Code for Design of Building Foundations" GB50007-2011, Articles 8.4.7 and 8.4.16. The influence of unbalanced bending moment is not considered when calculating the bottom plate punching shear coefficient. The bottom and top surfaces of the bottom plate should be equipped with stress-bearing steel bars according to the bending calculation, and the minimum reinforcement ratio should not be less than 0.15%. The bearing coefficient of the foundation columns of the raft foundation usually does not take into account the embedding effect of the side backfill soil. It is designed as an eccentrically tensile or compressive reinforced concrete member and the bearing capacity is verified according to the relevant provisions of Section 6.2 of the "Standard for Design of Concrete Structures" GB / T 50010-2010.

[0095] In some embodiments, including a single pile foundation, an independent cap multi-pile foundation, or a raft cap multi-pile foundation, the calculation coefficient includes a single pile vertical compressive bearing coefficient and a single pile vertical pull-out bearing coefficient. For example, the single pile vertical compressive bearing coefficient is determined by the corresponding single pile vertical compressive bearing control parameter and the single pile vertical bearing control parameter limit, wherein the single pile vertical compressive bearing control parameter = , where N k is the vertical pressure of the pile under the standard combination of load effects, N kmax Then N k Max. R a is the characteristic value of the vertical bearing capacity of the pile:

[0096] (twenty one)

[0097] Where, Q uk The standard value of the vertical ultimate bearing capacity of a single pile is determined based on the empirical parameter method and in accordance with Section 5.3 of the Technical Specification for Building Pile Foundations JGJ94-2008. It is necessary to comprehensively consider large-diameter piles, expanded-base piles, rock-socketed piles, and soil liquefaction effects. For single pile foundations:

[0098] N k =F k +G k (twenty two)

[0099] For multi-pile foundations, calculation is based on bi-directional eccentric loads:

[0100] (twenty three)

[0101] Where, is the vertical force acting on the top surface of the cap under the standard combination of load effects; The standard value of the deadweight of the pile foundation cap and the soil on the cap. The buoyancy of water should be deducted for the part below the stable groundwater level. is the average vertical force of the pile under the action of the standard combined axial vertical force of the load effect; is the vertical force of the i-th pile under the action of the eccentric vertical force of the standard combination of load effects; 、 The load acting on the bottom surface of the pile cap and passing through the centroid of the pile group under the standard combination of load effects is 、 The torque of the main shaft; 、 、 、 For the 、 Foundation pile to 、 Axis distance; is the number of piles in the pile foundation.

[0102] For a multi-pile foundation, the vertical pull-out bearing coefficient of a single pile is determined by the corresponding single pile vertical pull-out control parameter and the limit value of the single pile vertical pull-out control parameter (for example, the limit value is 1.0). The corresponding single pile vertical pull-out control parameter is usually determined according to the bidirectional eccentricity method:

[0103] X 抗拔 =N 抗拔 / (T uk / 2+G p ) (twenty four)

[0104] Among them, for single pile foundation:

[0105] N 抗拔 =F 2k -G k (25)

[0106] For multi-pile foundations, the corresponding N is calculated according to formula (23) for bidirectional eccentric load. 抗拔 , F k is the standard value of pressure, F 2k is the standard value of the pull-out force. ——The standard value of the ultimate pull-out bearing capacity of the pile foundation shall be determined in accordance with Article 5.4.6 of the Technical Specification for Building Pile Foundations JGJ94-2008; ——The dead weight of the foundation pile is taken as the floating weight below the groundwater level. For the expanded base pile, the circumference of the pile and soil column should be determined according to Table 5.4.6-1 of the Technical Specifications for Building Pile Foundations JGJ94-2008.

[0107] In some embodiments, the foundation type information includes a single pile foundation; the calculation coefficient also includes the pile body bearing coefficient. For example, for a single pile foundation, the pile body bearing coefficient is verified based on the compression and tension states. For a compression pile:

[0108] (26)

[0109] In formula (26), 1 is the design value of the axial pressure at the pile top under the basic combination of load effects; is the pile construction coefficient, determined according to Article 5.8.3 of the Technical Specifications for Building Pile Foundations JGJ94-2008; is the cross-sectional area of ​​the pile body.

[0110] For pull-out piles:

[0112] In formula (27), 2 is the design value of the axial tension at the pile top under the basic combination of load effects; is the design value of steel bar tensile strength; is the cross-sectional area of ​​the steel bar. If the calculation passes, the corresponding pile body bearing control coefficient can be determined based on the pile body bearing control parameter and the pile body bearing control parameter limit.
