[0028] Embodiment 1

[0029] According to an embodiment of the present invention, there is provided an embodiment of a method for obtaining a three-dimensional model of a lattice tower foundation. 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 the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0030] Figure 1 The flowchart of a method for obtaining a three-dimensional model of a lattice tower foundation according to an embodiment of the present invention is shown. This 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 corresponding to the lattice tower foundation. The method includes step S101, step S102, and step S103. In step S101, obtain the foundation type information, basic information, calculation information, and geological exploration information corresponding to the target lattice tower foundation. Among them, the basic information includes the foundation shape information of the target lattice tower foundation, the calculation information includes calculation parameter information for indicating the force details of the target lattice tower foundation, and the geological exploration information includes soil layer parameter information for indicating the location where the target lattice tower foundation is located; in step S102, determine a suitable initial foundation model according to the foundation type information of the target lattice tower foundation; in step S103, establish or update the display model of the target lattice tower foundation according to the initial foundation model and the basic information, and establish or update the calculation model of the target lattice tower foundation according to the display model, the calculation information, and the geological exploration information to obtain the three-dimensional model of the target lattice tower foundation. Among them, the computer device includes but is not limited to a user terminal device, a network device, or a device formed by integrating a user terminal device and a network device through a network. The user terminal device includes but is not limited to any mobile electronic product that can perform human-computer interaction with the user terminal (such as human-computer interaction through a touchpad), such as a smart phone, a tablet computer, etc.; the network device includes but is not limited to a computer, a network host, a single network server, a set of multiple network servers, or a cloud formed by multiple servers.

[0031] Specifically, in step S101, the basic type information, basic information, calculation information, and geological exploration information corresponding to the target lattice tower foundation are obtained. Among them, the basic information includes the basic form information of the target lattice tower foundation, the calculation information includes the calculation parameter information indicating the force details of the target lattice tower foundation, and the geological exploration information includes the soil layer parameter information indicating the location where the target lattice tower foundation is located. For example, the computer device obtains the modeling data required for the 3D modeling of the target lattice tower foundation according to the data requirements of the management personnel, such as the basic type information, basic information, calculation information, and geological exploration information corresponding to the target lattice tower foundation. The computer device respectively obtains the display model and calculation model of the target lattice tower foundation based on the obtained modeling data, so as to determine the 3D model of the target lattice tower foundation. Among them, the display model is used to present the 3D form and structure of the target lattice tower foundation through specific software, and the calculation model is used to display the force analysis calculation based on the form, structure, and materials of the target lattice tower foundation. The calculation model can be superimposed on the display model to determine the integrated 3D model of the lattice tower foundation, or the calculation model can be displayed separately from the display model to determine the intuitive and specific 3D model of the lattice tower foundation. The number of target lattice tower foundations can be one or more, which is not limited here. If the number of target lattice tower foundations is multiple, the modeling process corresponding to the following embodiments is executed for each target lattice tower foundation to obtain the 3D models of the multiple target lattice tower foundations. The basic information of the target lattice tower foundation includes the basic form information for describing the form, structure, etc. of the target lattice tower foundation. For example, the lattice tower cross-section, foundation root opening, distance from the connecting beam to the ground surface, height of the connecting beam, width of the connecting beam, buried depth, thickness of the bottom plate, width of the foundation column, side length of the bottom plate, and height of the foundation column above the ground, etc.; the calculation information includes multiple calculation parameter information for describing the force condition of the target lattice tower foundation. For example, the standard value of the maximum column top pressure, the design value of the maximum column top pressure, the standard value of the column top shear force, the design value of the column top shear force, the design value of the maximum uplift force at the column top, the standard value of the maximum uplift force at the column top, the design value of the column top shear force, the unit weight of concrete, etc.; the geological exploration information includes the soil layer parameter information indicating the location where the target lattice tower foundation is located. For example, the elevation of the groundwater level, soil layer number, soil layer name, soil layer depth, soil layer thickness, unit weight of the soil layer, etc.

Specifically, in some embodiments, the basic type information includes, but is not limited to: isolated foundation; raft foundation; single-pile foundation; isolated pile cap multi-pile foundation; raft pile cap multi-pile foundation. Among them, the isolated foundation is an extended foundation used to support a single column of the upper conventional tower structure; the raft foundation is an extended foundation used to support the entire upper conventional tower structure (multiple columns); the single-pile foundation is a foundation composed of a single pile (steel pipe pile or cast-in-place concrete pile) and is used to support a single column of the upper conventional tower structure; the multi-pile foundation is a foundation composed of multiple piles (cast-in-place concrete piles or precast piles) and a pile cap connected to the pile top and is used to support a single column or the entire upper conventional tower structure (multiple columns). The pile cap multi-pile foundation includes a foundation composed of multiple piles (cast-in-place concrete piles or precast piles) and a pile cap connected to the pile top and is used to support a single column or the entire upper conventional tower structure (multiple columns). When the upper structure supported by the pile cap is a single tower column of a lattice tower, such a foundation is called an isolated pile cap multi-pile foundation. When the upper structure supported by the pile cap is the entire lattice tower (all tower columns), such a foundation is called a raft pile cap multi-pile foundation. Of course, those skilled in the art should understand that the above basic type information is only an example. Other existing or future possible basic type information that can be applied to the present invention should also be included within the protection scope of the present invention and is hereby incorporated by reference. For the lattice tower foundations of certain basic types, there may also be classifications of various subtype information. For example, the isolated pile cap multi-pile foundation includes basic subtype information such as cast-in-place concrete piles, precast square piles, and rock anchors. Also, for example, the raft pile cap multi-pile foundation includes basic subtype information such as cast-in-place concrete piles, precast square piles, and rock anchors.

[0033] Specifically, when the foundation type information of the lattice tower foundation includes isolated foundations, 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 height of the connecting beam, the width of the connecting beam, the embedment depth, the thickness of the bottom slab, the width of the foundation column, the side length of the bottom slab, and the height of the foundation column above the ground, etc.; the corresponding calculation information includes the standard value of the maximum pressure at the column top, the design value of the maximum pressure at the column top, the standard value of the shear force at the column top, the design value of the shear force at the column top, the design value of the maximum uplift force at the column top, the standard value of the maximum uplift force at the column top, the design value of the shear force at the column top, the unit weight of concrete, the concrete strength grade, the steel bar grade, the distance from the resultant force point of the longitudinal reinforcement of the bottom slab to the section edge, the distance from the resultant force point of the longitudinal reinforcement on one side of the foundation column to the section edge, the corrected characteristic value of the foundation bearing capacity, the critical depth calculated by the soil weight method, and the soil uplift angle, etc.; the corresponding geological exploration information includes the elevation of the groundwater level, the number of soil layers (rocks), the name of the soil layer (rock), the depth of the soil layer (rock), the thickness of the soil layer (rock), the unit weight of the soil layer, the soil compression modulus, the characteristic value of the foundation bearing capacity of each soil layer, the standard value of the rock compressive strength, the rock integrity (for example, relatively fractured rock mass, relatively intact rock, intact rock), etc. Herein, the soil layer referred to in the present invention is used to indicate the soil layer parameters corresponding to each soil layer. For example, the number of soil layers (rocks) is used to indicate the number of each soil layer (rock), etc. Correspondingly, the depth of the soil layer (rock) is used to indicate the bottom elevation of each soil layer (rock).

[0034] For example, when the foundation type information of the lattice tower foundation includes a raft 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 height of the connecting beam, the width of the connecting beam, the buried depth, the thickness of the bottom slab, the width of the foundation column, the dimension of the foundation column above the ground, the side length of the bottom slab, 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 moment, the design value of the foundation top moment, the maximum design value of the column top pressure, the design value of the column top shear force, the maximum design value of the column top uplift force, the design value of the column top shear force, the concrete unit weight, the concrete strength grade, the steel bar grade, the distance from the resultant point of the bottom slab longitudinal reinforcement to the section edge, the distance from the resultant point of the longitudinal reinforcement on one side of the foundation column to the section edge, the corrected characteristic value of the foundation bearing capacity, etc.; the corresponding geological exploration information includes the elevation of the groundwater level, the number of soil layers (rocks), the name of the soil layer (rock), the depth of the soil layer (rock), the thickness of the soil layer (rock), the soil layer unit 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 rock integrity (e.g., relatively fractured rock mass, relatively intact rock, intact rock), etc. When the foundation type information of the lattice tower foundation includes a cast-in-place concrete single-pile foundation of a single-pile foundation, the corresponding basic information includes whether to set a bearing platform, the buried depth, the thickness of the bottom slab, the width of the foundation column, the width of the bottom slab, the length of the bottom slab, the dimension of the foundation column above the ground, the pile length, the pile diameter, whether to have an enlarged bottom, 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 moment, the design value of the foundation top moment, the concrete strength grade, the radius of the circumference where the longitudinal reinforcement is located, the total cross-sectional area of the longitudinal reinforcement of the foundation pile, the pile-forming process coefficient, the bottom diameter of the enlarged-bottom pile, the height of the variable cross-section and inclined surface at the bottom of the enlarged-bottom pile, the comprehensive coefficient of the rock-socketed section, etc.; the corresponding geological exploration information includes the elevation of the groundwater level, the number of soil layers (rocks), the name of the soil layer (rock), the depth of the soil layer (rock), the thickness of the soil layer (rock), the soil layer unit weight, the m value of the soil layer, the soil type (divided into fill soil, clay, silt, sand, gravel), the side friction of the cast-in-place pile (the side friction of the pile for each soil layer), the end resistance of the cast-in-place pile (the end resistance of the pile for each soil layer), the standard value of the rock compressive strength, etc. It should be noted that the m value of the soil layer refers to the proportional coefficient of the horizontal resistance coefficient of the soil layer, which is a parameter used in soil mechanics to quantify the ability of the soil layer to resist external forces in the horizontal direction. Its unit is MN / m 4 (or equivalent unit). 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 mass on the structure.

[0035] For example, if the foundation type information of the lattice tower foundation includes 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 height of the connecting beam, the width of the connecting beam, whether to set a bearing platform, the buried depth, the thickness of the bottom plate, the width of the foundation column, the side length of the bottom plate, the height of the foundation column above the ground, the height of the pile top above the ground, the pile length, the pile diameter, whether to have an enlarged bottom, etc.; the corresponding calculation information includes the standard value of the maximum pressure at the pile top, the design value of the maximum pressure at the pile top, the standard value of the maximum uplift force at the pile top, the design value of the maximum uplift force at the pile top, the concrete specific gravity, the concrete strength grade, the steel bar grade, the total cross-sectional area of all longitudinal steel bars of the foundation pile, the pile-forming process coefficient, the bottom diameter of the enlarged-bottom pile, the variable cross-section and inclined plane height at the bottom of the enlarged-bottom pile, and the comprehensive coefficient of the rock-socketed section (e.g., related to the depth-diameter ratio of the rock-socketed section, the hardness of the rock, and the pile-forming process), etc.; the corresponding geological exploration information includes the elevation of the groundwater level, the number of soil layers (rocks), the name of the soil layer (rock), the depth of the soil layer (rock), the thickness of the soil layer (rock), the soil specific gravity, the soil type (e.g., fill soil, clay, silt, sand, gravel), the side friction of precast piles / pipe piles, the end resistance of precast piles / pipe piles, the side friction of cast-in-place piles, the end resistance of cast-in-place piles, the uplift coefficient, and the standard value of the rock compressive strength, etc.

[0037] For example, if the foundation type information of the lattice tower foundation includes a raft cap multi-pile foundation, the corresponding basic information includes the cross-section of the lattice tower, the foundation root opening, whether a connecting beam is set, the distance from the connecting beam to the ground plane, the height of the connecting beam, the width of the connecting beam, the burial depth, the thickness of the bottom slab, the width of the foundation column, the side length of the bottom slab, the height of the foundation column above the ground, the pile type (for example, divided into cast-in-place concrete piles, precast square piles, rock bolts), the pile length (the pile length corresponding to each pile type), the pile size, the number of rows of pile arrangement, the number of columns of pile arrangement, the horizontal edge distance of the piles (the horizontal distance from the center of the outermost pile to the edge of the cap), and the vertical edge distance of the piles (the vertical distance from the center of the outermost pile to the edge of the cap), etc.; the corresponding calculation information includes the standard value of the top pressure of the foundation, the design value of the top pressure of the foundation, the standard value of the horizontal force at the top of the foundation, the design value of the horizontal force at the top of the foundation, the standard value of the bending moment at the top of the foundation, the design value of the bending moment at the top of the foundation, the unit weight of concrete, the concrete strength grade, the grade of steel bars, the total cross-sectional area of all longitudinal steel bars of the foundation piles, the distance from the resultant force point of the bottom slab longitudinal reinforcement to the edge of the section, the pile-forming process coefficient, and the comprehensive coefficient of the rock-socketed section (related to the depth-diameter ratio of the rock-socketed section, the hardness of the rock, and the pile-forming process), etc.; the corresponding geological exploration information includes the elevation of the groundwater level, the number of soil layers (rocks), the name of the soil layer (rock), the depth of the soil layer (rock), the thickness of the soil layer (rock), the unit weight of the soil layer, the soil type, the side friction of precast piles / pipe piles, the end resistance of precast piles / pipe piles, the side friction of cast-in-place piles, the end resistance of cast-in-place piles, the uplift coefficient, the bond strength (the standard value of the ultimate bond strength between the rock and the anchor), the hardness of the rock (soft rock, relatively soft rock, hard rock, used for estimation when the bond strength parameter is lacking in geological exploration), and the standard value of the compressive strength of the rock, etc.

[0038] Of course, those skilled in the art should understand that the above basic information, calculation information, and geological exploration information are only examples. Other existing or future possible basic information, calculation information, and geological exploration information that can be applied to the present invention should also be included within the protection scope of the present invention and are hereby incorporated herein by reference.

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

[0040] In step S102, a corresponding initial foundation model is determined according to the foundation type information of the target lattice tower foundation. For example, after the computer device obtains the input modeling data, it can establish a corresponding display model and calculation model based on the modeling data. Among them, before determining the display model, the computer device first determines the corresponding initial foundation model according to the foundation type information, and then inputs the basic information of the target lattice tower foundation into the initial foundation model to generate the display model of the target lattice tower foundation. The initial foundation model is used to indicate the basic model of the physical structure of the target lattice tower foundation corresponding to the corresponding foundation type information and the modeling rules of the corresponding basic model, such as the tower foot flange model, the foundation cap model, the foundation cushion model, the foundation enclosure model, and / or the foundation pile model, etc. Different initial modules with different shapes and structures can be set according to different requirements.

[0041] Specifically, when the foundation type information of the lattice tower foundation includes independent foundations, the corresponding initial foundation model includes a foundation cap model, a foundation cushion model, and a foundation enclosure model. Among them, the outline dimensions of the foundation cap: the foundation root opening, the foundation bottom plate size, and the foundation column size need to be modeled at a 1:1 ratio, with the length unit being "millimeters (mm)".

Among them, the outline dimensions of the foundation raft: the raft size, the foundation column size, and the foundation root opening need to be modeled at a 1:1 ratio, with the length unit being "millimeters (mm)". The height of the foundation enclosure model is modeled at 300 mm, the foundation cushion model is modeled by expanding 100 mm from the foundation bottom plate with a thickness of 100 mm. In some cases, a continuous beam can also be set in the initial foundation model of the raft model, and the three-dimensional model of the continuous beam part is displayed. When the foundation type information of the lattice tower foundation includes steel pipe pile foundations of single-pile foundations, the corresponding initial foundation model includes a tower foot flange model and a foundation steel pipe model. Among them, the foundation diameter and pile length of the foundation steel pipe model need to be modeled at a 1:1 ratio, with the length unit being "millimeters (mm)", and the thickness of the foundation steel pipe model is modeled at a fixed 20 mm. When the foundation type information of the lattice tower foundation includes single-pile foundations, the corresponding initial foundation model includes a foundation cap model and a foundation enclosure model. Among them, the bottom plate size of the foundation cap model, the foundation column size, the diameter of the cast-in-place pile, and the pile length need to be modeled at a 1:1 ratio, with the length unit being "millimeters (mm)", and the height of the foundation enclosure model is modeled at 300 mm; when a foundation cap is set, the model should include a foundation cap cushion model, and the cushion is modeled by expanding 100 mm from the foundation cap bottom plate with a thickness of 100 mm. When the foundation type information of the lattice tower foundation includes independent pile caps with multiple piles, the corresponding initial foundation model includes a foundation cap model, a foundation cushion model, a foundation enclosure model, and corresponding multiple foundation pile models. Among them, the outline dimensions of the foundation cap: the bottom plate size of the foundation cap, the foundation column size, the pile size, the pile length, and the pile layout information need to be modeled at a 1:1 ratio, with the length unit being "millimeters (mm)", the height of the foundation enclosure model is modeled at 300 mm, and the foundation cushion model is modeled by expanding 100 mm from the foundation bottom plate with a thickness of 100 mm. In some cases, the initial foundation model of the independent pile cap with multiple piles should also include continuous beam information, and 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 bolts, etc.When the foundation type information of the 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 enclosure model, and a corresponding plurality of foundation pile models. Among them, the outline dimensions of the foundation raft: raft dimensions, foundation column dimensions, pile dimensions, pile length, and pile layout information need to be modeled at a 1:1 ratio, with the length unit being "millimeters (mm)". The height of the foundation enclosure model is modeled at 300 mm, and the foundation cushion model is modeled by expanding 100 mm from the foundation bottom slab with a thickness of 100 mm. In some cases, the initial foundation model of the raft cap multi-pile foundation should also include the information of the connecting beam. The plurality of foundation pile models include at least one of, but not limited to, cast-in-place concrete piles, precast square piles, and rock bolts. Of course, those skilled in the art should understand that the above modeling rules are only examples. Other existing or future possible modeling rules that can be applied to the present invention should also be included within the protection scope of the present invention and are hereby incorporated by reference.

[0042] In step S103, based on the initial foundation model and the basic information, establish or update the display model of the target lattice tower foundation. Based on the display model, the calculation information, and the geological exploration information, establish or update the calculation model of the target lattice tower foundation to obtain the three-dimensional model of the target lattice tower foundation. For example, after the computer device obtains the initial foundation model of the target lattice tower foundation, it adjusts the initial foundation model according to the model parameters in the basic information of the target lattice tower foundation to obtain the three-dimensional display model of the target lattice tower foundation. Based on this display model, the computer device can combine the calculation information and the geological exploration information, etc., to model the stress condition of the target lattice tower foundation to obtain the corresponding calculation model. For example, determine the corresponding calculation model based on the structure of the target lattice tower foundation in the display model and the calculation model parameters (parameters available for calculation included in the calculation information and the geological exploration information). The calculation model can be used to calculate the bearing state information of the target lattice tower foundation, and the bearing state information is used to indicate the uplift resistance, compressive resistance, anti-overturning, and bearing capacity analysis of each structure in the target lattice tower foundation.

[0043] For the convenience of data analysis and management, the computer device stores the obtained display model and calculation model of the target lattice tower foundation in the database. In some embodiments, the method further includes step S104 (not shown). In step S104, the basic identification information and basic position information of the target lattice tower foundation are obtained, and the target basic record information of the target lattice tower foundation is determined based on the basic identification information, basic position information, and three-dimensional model; a corresponding lattice tower foundation modeling system is established or updated according to the target basic record information, wherein the lattice tower foundation modeling system includes one or more lattice tower foundation record information. For example, while obtaining the modeling data of the target lattice tower foundation, the computer device can also obtain the basic identification information, basic position information, etc. of the target lattice tower foundation. The basic identification information is used to uniquely identify the lattice tower foundation, such as sequential number, serial number, or coding based on a preset rule, etc.; the basic position information is used to locate the spatial position of the lattice tower foundation, such as longitude and latitude, electronic map position, etc. The computer device can generate the lattice tower foundation record information about the target lattice tower foundation according to the basic identification information, basic position information, and corresponding three-dimensional model of the target lattice tower foundation, and then enter the lattice tower foundation record information into the corresponding lattice tower foundation modeling system. The lattice tower foundation modeling system is used to model multiple lattice tower foundations and realize information entry, so as to facilitate querying, management, etc. of multiple lattice tower foundations. In some embodiments, the computer device can also obtain the bearing state information of the target lattice tower foundation, and determine whether to enter the target lattice tower foundation into the system based on whether the bearing state information meets the preset requirements, such as whether the current bearing coefficient is less than or equal to the preset coefficient threshold, or whether the bearing capacity index of the target lattice tower foundation has a surplus or is fully loaded, etc. For the target lattice tower foundation that exceeds the limit, the parameters need to be modified and then the corresponding information needs to be re-entered. When the computer device enters the information of the target lattice tower foundation, the lattice tower foundation record information is added with the bearing state information and then entered into the lattice tower foundation modeling system together for subsequent data verification, etc.

[0044] In some embodiments, the method further includes step S105 (not shown). In step S105, if a display operation of the target base record information of the target lattice tower foundation is obtained from the client, a three-dimensional model of the target lattice tower foundation is presented. For example, the computer device may present the three-dimensional model of the target lattice tower foundation on the corresponding page based on the display operation of the target base record information from the client (such as clicking or selecting to view, etc.). For example, click to enter the viewing page of the target lattice tower foundation to present the three-dimensional model on the viewing page. In some cases, the corresponding lattice tower foundation record information includes the base location information of the target lattice tower foundation. Based on the call operation of the client (such as the client's call based on the lattice tower foundation name or serial number, or the call of some or all of the lattice tower foundation data in a certain area, etc.), the computer device may retrieve the base locations of one or more corresponding lattice tower foundations, and present the base identification information of each lattice tower foundation on the map based on the base locations. Specifically, when the call request includes the lattice tower foundation identification of the target lattice tower foundation, while presenting the base identification information of the target lattice tower foundation in the electronic map based on the base location information of the target lattice tower foundation, a three-dimensional model of the target lattice tower foundation is presented in the form of a label, etc. Among them, the computer device may obtain the corresponding map coordinates according to the stored longitude and latitude and present the base 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 three-dimensional model is obtained from the client, corresponding parameter modification information is determined according to the modification operation, and the model parameter information of the three-dimensional model of the target lattice tower foundation is adjusted based on the parameter modification information. For example, the modification operation may be a parameter modification directly performed by the management client on the parameter page, or a modification operation on the components / forms of the model in the three-dimensional model, etc. Specifically, the computer device can present the three-dimensional model of the target lattice tower foundation to the client through the corresponding display device. Correspondingly, a setting control for modifying the lattice tower foundation parameters is included in this presentation page. When a touch operation on the control for parameter modification is obtained from the client, the computer device can directly obtain the corresponding parameter modification information based on this touch operation for direct parameter modification; or, a corresponding model modification control is further included in the three-dimensional view presentation page corresponding to the corresponding three-dimensional model. The client can achieve view modification of the three-dimensional model through direct touch modification of the model, such as deleting, modifying, or adding basic components, etc., and also such as modifying the height of the bearing platform. The computer device can inversely calculate the corresponding parameter modification information based on the modification of the client on the three-dimensional model, and adjust the model parameter information of the stored three-dimensional model based on this parameter modification information, etc. After the computer device obtains the corresponding modification operation, it will synchronize the adjusted parameter modification information corresponding to this modification operation to the lattice tower foundation record information of the target lattice tower foundation and synchronize it to the local database. At the same time, when further updating the three-dimensional model of the target lattice tower foundation to adjust it to the three-dimensional model after the operation, 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 which a query request for foundation distribution information and / or foundation bearing distribution information of a lattice tower foundation is obtained. The query request includes a target area to be queried. In response to the query request, the foundation distribution information and the foundation bearing distribution information corresponding to the lattice tower foundation in the target area are presented in the lattice tower foundation modeling system. For example, the foundation distribution information is used to indicate the quantity / ratio information of the lattice tower foundations accounted for by each factor divided based on specific factors (such as geographical location, foundation type information, etc.) among the multiple lattice tower foundations stored in the lattice tower foundation modeling system. The foundation bearing capacity distribution information is used to indicate the quantity or ratio of the multiple entered lattice tower foundations in each bearing state information (such as fully loaded, having surplus, overlimit, etc.). The multiple lattice tower foundations may be all the lattice tower foundations in the lattice tower foundation modeling system, or may be a selected part of the lattice tower foundations from all the lattice tower foundations, etc., such as being screened based on a circled area or foundation type information, or based on the check of the management user terminal, etc., which is not limited herein. For example, the bearing capacity of the lattice tower foundations in a certain City A is: 20% fully loaded, 20% having surplus, 60% overlimit, etc. Through the foregoing statistical data, the foundation distribution information and / or the bearing distribution information of the currently entered lattice tower foundations can be intuitively presented to the user terminal. When the number of entered lattice tower foundations is large enough and the range is wide enough, this data is usually used to indicate the overall bearing distribution information of all the lattice tower foundations nationwide, etc. Of course, when the number of entered lattice tower foundations is large enough, sometimes it is necessary to statistically analyze the corresponding lattice tower foundation data in a specified target area (such as a certain city or a calibrated target area, etc.) to determine and present the foundation bearing distribution information and the foundation distribution information of the corresponding area, etc. In some cases, the computer device can also display a trend chart of the entered lattice tower foundations over time (such as one month, one year, or three years, etc.) in a certain city based on the query operation of the user terminal, or display the number of entered lattice tower foundations of each branch company, etc.

[0047] In some embodiments, the method further includes step S108 (not shown), in which the bearing capacity coefficient of the target lattice tower foundation is determined according to the display model, the calculation model, the calculation information, and the geological survey information; the bearing state information of the target lattice tower is determined according to the bearing capacity coefficient, wherein the bearing state information includes over-limit, full load, or surplus. For example, the computer device can calculate the bearing state information of the lattice tower foundation through the aforementioned parameters and the calculation model, such as calculating one or more state parameters of the corresponding foundation bearing capacity, foundation strength, single pile bearing capacity, and foundation stability, and determine the bearing state information of the lattice tower foundation based on the calculated result, such as whether it is over-limit, full load, or there is still surplus at present. Among them, the aforementioned state parameters are different based on the different foundation type information of the target lattice tower foundation, such as an independent foundation only needs to determine the state parameters related to the foundation bearing capacity and foundation strength, and a single pile foundation needs to determine the corresponding bearing state information through state parameters such as foundation strength and single pile bearing capacity. In some cases, each state parameter of the aforementioned foundation bearing capacity, foundation strength, single pile bearing capacity, and foundation stability is characterized by one or more calculation coefficients. For example, the foundation bearing capacity includes at least one of the foundation bearing coefficient, the base detachment area coefficient, and the weak underlying layer bearing coefficient, the foundation strength includes at least one of the bottom plate bending bearing coefficient, the bottom plate shear resistance, the column bearing coefficient, and the pile body bearing coefficient, the single pile bearing capacity includes at least one of the single pile foundation pile top horizontal displacement coefficient, the single pile foundation rotation angle, the single pile vertical compressive bearing coefficient, and the single pile vertical pull-out bearing coefficient, and the foundation stability includes at least one of the foundation pull-out coefficient, the foundation anti-overturning coefficient, and the foundation anti-slip coefficient. The aforementioned state parameters are only examples. The state parameters required to be calculated for lattice tower foundations of different foundation type information are different. The corresponding type of lattice tower foundation bearing state information is analyzed and obtained according to different structures and types; the calculation requirements of lattice tower foundations of different foundation type information for multiple calculation coefficients in the same state parameter are also different. 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 according to the bearing capacity coefficient includes: if the bearing capacity coefficient is greater than 100%, determining that the bearing state information of the target lattice tower is over-limit; if the bearing capacity coefficient is less than or equal to 100% and greater than the preset coefficient threshold, determining that the bearing state information of the target lattice tower is fully loaded; if the bearing capacity coefficient is less than or equal to the preset coefficient threshold, determining that the bearing state information of the target lattice tower has a surplus. For example, after the computer device obtains the calculation coefficients included in one or more state parameters, it determines the bearing capacity coefficient for the lattice tower foundation according to the multiple calculation coefficients, and compares the bearing capacity coefficient with the preset coefficient threshold to determine the bearing state information of the target lattice tower foundation. If it is greater than the first preset coefficient threshold, it is determined to be over-limit. If it is less than or equal to the first preset coefficient threshold and greater than the second preset coefficient threshold, it is determined to be fully loaded. If it is less than or equal to the second preset coefficient threshold, it is determined that the bearing state information has a surplus, etc. Specifically, in order to intuitively reflect whether it is over-limit, the first preset coefficient threshold is usually set to 100%. Then, when the bearing capacity coefficient is greater than 100%, it is determined that the bearing state information of the target lattice tower foundation is over-limit; if the bearing capacity coefficient is less than or equal to 100% and greater than the preset coefficient threshold (for example, 95%, 80%, etc.), it is determined that the bearing state information of the target lattice tower foundation is fully loaded; if the bearing capacity coefficient is less than or equal to the preset coefficient threshold, it is determined that the bearing state information of the target lattice tower foundation has a surplus.

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

[0050] Here, for the lattice tower foundation of different basic type information, it is usually necessary to comprehensively consider its bearing state information by referring to different coefficients in different state parameters. For example, in some embodiments, the basic type information includes independent foundations; among them, the calculation coefficients include the foundation bearing coefficient and the foundation uplift 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 value of the foundation bearing control parameter (for example, the value is 1.0), where 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] In the formula, is the foundation bearing control parameter, is the average pressure (kPa) at the bottom surface of the foundation corresponding to the standard combination of actions; is the characteristic value of the corrected foundation bearing capacity; is the maximum pressure value (kPa) at the edge of the bottom surface of the foundation corresponding to the standard combination of actions. It should be noted that the standard combination of actions refers to the combination method that uses standard values or combination values as the representative values of loads in 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 service limit state. Among them,

[0053] 1) When the foundation bears axial load, the pressure at the bottom surface of the foundation can be calculated by the following formula:

[0054] (2)

[0055] In the formula, is the vertical force value (kN) transmitted from the superstructure to the foundation corresponding to the standard combination of actions; is the standard value of the self-weight of the foundation and the soil weight on the foundation (kN); A is the area of the bottom surface of the foundation (m 2 ). Among them, = concrete unit weight (weighted average considering water level) × concrete volume + soil unit weight (weighted average considering water level) × soil volume.

[0056] 2) When the foundation bears unidirectional eccentric load, the pressure at the bottom surface of the foundation is calculated by the following formula:

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

[0058] If p kmin ≥ 0, then:

[0059] If p kmin < 0, refer to Figure 2 ( Figure 2 showing the base pressure when the base of the foundation is partially separated under the action of a unidirectional eccentric load according to an embodiment of the present invention), then:

[0060] (6)

[0061] (7)

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

[0063] 3) When the foundation bears a bi-directional eccentric load, refer to Figure 3 ( Figure 3 showing the base pressure when the base of the foundation is partially separated under the action of a bi-directional eccentric load according to an embodiment of the present invention), the base pressure of the foundation can be calculated by the following formula:

[0064] (8)

[0065] In the formula, M kx , M ky are the moment values (kN·m) of the upper structure transmitted to the foundation base with respect to the x and y axes respectively corresponding to the standard combination of the actions; W x , W y are the moment resistances of the foundation base with respect to 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 is the distance from the resultant force action point to the edge of the foundation on one side of e x is the distance from the resultant force action point to the edge of the foundation on one side of e y is the distance from the resultant force action point to the edge of the foundation on one side of e y is the distance from the resultant force action point to the edge of the foundation on one side of e x is the eccentricity in the x direction, and e y is the eccentricity in the y direction, and l is Figure 3 the length of the bottom surface of the foundation parallel to the y-axis shown in. Based on the foregoing process, the foundation bearing coefficient of the isolated foundation can be obtained. Here, for the isolated foundation of the lattice tower, the corresponding foundation bearing coefficient is calculated according to the case of axial load. For the raft foundation of the lattice tower, etc., the corresponding foundation bearing coefficient can be calculated according to the cases of axial load, unidirectional eccentric load or bidirectional eccentric load according to specific situations.

[0074] For example, the foundation uplift stability coefficient is determined by calculating the ratio of the corresponding foundation uplift stability control parameter to the parameter limit value of the foundation uplift stability control parameter (for example, the value is 1.0). Among them, the foundation uplift stability control parameter is determined by the following method:

[0075] (15)

[0076] In the formula, is the maximum uplift force of the isolated foundation of the lattice tower; G e is the soil weight calculated according to Article 7.4.3 and Appendix J of the "Design Standard for High-Rise Structures" GB50135-2019; is the foundation weight, and this = concrete unit weight (weighted average considering water level) × concrete volume.

[0077] In some cases, in addition to the foregoing necessary factors, there are also some non-necessary factors for auxiliary reference. For example, in some embodiments, the calculation coefficient also includes at least one of the bottom plate bending bearing coefficient, soft soil stratum bearing coefficient, bottom plate punching shear coefficient, and column bearing coefficient. For example, here, Figure 4 shows the load calculation of the spread foundation according to an embodiment of the present invention. As Figure 4 shown, under the action of axial load or unidirectional eccentric load, the bending moments of the intersection sections of the foundation columns and the bottom plate in two directions are calculated respectively, and the bottom plate bending bearing coefficient is calculated according to Equation 8.2.12 of the "Code for Design of Building Foundation" GB50007-2011, and the minimum reinforcement ratio requirement should be met:

[0078] (16)

[0079] In the formula, M is the design value of the bending moment borne by the foundation bottom plate, and As is the reinforcement area calculated according to the calculation (mm 2), 0.9 is a fixed parameter, and 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 centroid of the resultant force of the tensile steel bars.

[0080] In addition, when calculating the internal force of any section , the design value p0 of the uniform load on the foundation base obtained by the following formula can be used:

[0081] p0 = (17)

[0082] In the formula, p0 is the uniform load on the foundation base (kPa), and p max is the maximum pressure at the edge of the foundation base formed by the internal force transmitted from the top surface of the foundation (kPa), and p x is the foundation base pressure at the calculated section formed by the internal force transmitted from the top surface of the foundation (kPa).

[0083] In some cases, it is also necessary to calculate the top surface reinforcement. When the foundation bears uplift force, the anti-uplift strength calculation of the bottom slab should be carried out. Negative moment steel bars should be arranged on the upper surface of the bottom slab according to the calculation and should meet the minimum reinforcement ratio requirements. The design value p1 of the uniform load on the upper surface of the foundation can be obtained by the following formula:

[0084] p1 = (18)

[0085] In the formula, G is the self-weight of the foundation considering the action partial coefficient and the overburden weight within the anti-uplift angle range. The anti-uplift angle should be adopted in accordance with the provisions of Article 7.4.3 of the "Code for Design of High-Rise Structures" GB50135-2019; A is the area of the foundation bottom slab (m 2 ). When the foundation bears uplift force and both the bottom surface and the top surface are considered simultaneously, the unfavorable flexural bearing coefficient is taken. For lattice towers, basically both the bottom surface and the top surface need to be considered.

[0086] Here, when there is a weak underlying stratum within the scope of the foundation bearing, the bearing coefficient of the weak underlying stratum should be calculated according to relevant regulations. Among them, the control parameter of the weak underlying stratum coefficient is determined by the following formula:

[0087] (19)

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

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

[0090] The embedment effect of the side backfill soil on the foundation column is not considered. It is designed as a reinforced concrete member under eccentric tension or compression, and the bearing coefficient of the column is checked according to 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 raft foundation; the calculation coefficients include the foundation bearing coefficient and the base separation area coefficient. For example, the foundation bearing coefficient of the raft foundation is obtained in the same or similar way as that of the aforementioned isolated foundation. Also for example, the base separation area coefficient is determined by calculating the ratio of the corresponding base separation area control parameter to the parameter limit value of the base separation area control parameter (for example, the value is 1.0). Among them, the foundation bearing control parameter is determined by the following formula:

[0092] (20)

[0093] In the formula, is the foundation bearing control parameter, where a, b, a x 、a y are determined by the previous formulas (6) - (14).

[0094] In some embodiments, the calculation coefficients further include at least one of the bending resistance bearing coefficient of the bottom slab, the bearing coefficient of the soft soil stratum, the punching shear coefficient of the bottom slab, and the bearing coefficient of the column. Among them, the calculation methods of the bending resistance bearing coefficient of the bottom slab, the bearing coefficient of the soft soil stratum, the punching shear coefficient of the bottom slab, and the bearing coefficient of the column of the raft foundation are the same as or similar to the obtaining methods of the corresponding bending resistance bearing coefficient of the bottom slab, the bearing coefficient of the soft soil stratum, the punching shear coefficient of the bottom slab, and the bearing coefficient of the column of the independent foundation. Specifically, for example, the checking calculations of the punching shear coefficient and the bending resistance bearing coefficient of the bottom slab of the raft foundation shall be carried out according to the provisions of Articles 8.4.7 and 8.4.16 of the current standard Code for Design of Building Foundation GB50007-2011. When checking the punching shear coefficient of the bottom slab, the influence of the unbalanced moment is not considered. Reinforcing bars for flexure calculation shall be arranged on both the bottom and top surfaces of the bottom slab, and the minimum reinforcement ratio shall not be less than 0.15%. The bearing coefficient of the foundation column of the raft foundation generally does not consider the fixing effect of the side backfill soil, and is designed as a reinforced concrete member under eccentric tension or compression. The bearing capacity is checked 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, it includes single-pile foundation, independent pile cap multi-pile foundation or raft pile cap multi-pile foundation; among them, the calculation coefficients include the vertical compressive bearing coefficient of a single pile and the vertical uplift bearing coefficient of a single pile. For example, the vertical compressive bearing coefficient of a single pile is determined by the corresponding vertical compressive bearing control parameter of a single pile and the limit value of the vertical bearing control parameter of a single pile. Among them, the vertical compressive bearing control parameter of a single pile = , where N k is the vertical pressure of the foundation pile under the standard combination of load effects, and N kmax is the maximum value of N k .
