Technical Field

[0001] This invention relates to the field of building infrastructure technology, and in particular to a recommended method for pile foundations for railway bridges. Background Technology

[0002] The selection of railway bridge pile foundations is a key aspect of railway bridge construction. Therefore, the process requires a comprehensive analysis of various factors, including: the characteristics of the structure (structure type, load characteristics, pile function, safety level), topography, engineering geological conditions (soil layers traversed, soil and rock properties of the pile bearing layer), hydrogeological conditions (groundwater type, groundwater level), construction machinery and equipment, construction environment, construction experience, characteristics of various pile construction methods, supply conditions of pile materials, cost, and construction period. This process involves technical and economic analysis and comparison before finally determining the appropriate pile type and configuration. The process is cumbersome, and test piles are required before formal construction, consuming significant time and manpower, resulting in low efficiency, resource waste, and compromised safety. Summary of the Invention

[0003] The main objective of this invention is to provide a recommended method for railway bridge pile foundations, which aims to solve the technical problems of existing technologies that require a lot of time and manpower to determine the type and configuration of foundation piles, resulting in low efficiency, waste of resources, and inability to guarantee safety.

[0023] Optionally, you can choose to select a recommendation algorithm yourself or use the default recommendation algorithm;

[0024] When a recommendation algorithm is selected, the pile foundation configurations that conform to the rules corresponding to the recommendation algorithm in the pile foundation configuration database are obtained as the filtering results.

[0025] The pile foundation configuration is saved to the corresponding foundation configuration table in the project library to obtain the initial foundation scheme;

[0026] Determine whether the initial foundation scheme meets the engineering requirements for each pier;

[0027] When the initial basic scheme meets the engineering requirements, the initial basic scheme that meets the design requirements will be saved.

[0028] The corresponding pile foundation configuration is determined as a valid result in the screening results.

[0029] Optionally, after determining whether the initial foundation scheme meets the engineering requirements pier by pier, the method further includes:

[0057] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0058] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0059] Reference Figure 1 , Figure 1 This is a schematic diagram of the recommended equipment structure for railway bridge pile foundations in the hardware operating environment of the embodiments of the present invention.

[0060] like Figure 1 As shown, the recommended equipment for the railway bridge pile foundation may include: a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. The communication bus 1002 is used to enable communication between these components. The user interface 1003 may include a display screen or an input unit such as a keyboard; optionally, the user interface 1003 may also include a standard wired interface or a wireless interface. The network interface 1004 may optionally include a standard wired interface or a wireless interface (such as a Wireless-Fidelity (Wi-Fi) interface). The memory 1005 may be high-speed random access memory (RAM) or stable non-volatile memory (NVM), such as a disk storage device. The memory 1005 may also optionally be a storage device independent of the aforementioned processor 1001.

[0061] Those skilled in the art will understand that Figure 1 The structures shown do not constitute a limitation on recommended equipment for railway bridge pile foundations and may include more or fewer components than shown, or combinations of certain components, or different arrangements of components.

[0062] like Figure 1As shown, the memory 1005, which serves as a storage medium, may include an operating system, a network communication module, a user interface module, and a recommendation program for railway bridge pile foundations.

[0063] exist Figure 1 In the railway bridge pile foundation recommendation device shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and memory 1005 in the railway bridge pile foundation recommendation device of the present invention can be set in the railway bridge pile foundation recommendation device, and the railway bridge pile foundation recommendation device calls the railway bridge pile foundation recommendation program stored in the memory 1005 through the processor 1001 and executes the railway bridge pile foundation recommendation method provided in the embodiment of the present invention.

[0064] This invention provides a recommended method for railway bridge pile foundations, referring to... Figure 2 , Figure 2 This is a flowchart illustrating the first embodiment of the recommended method for railway bridge pile foundations of the present invention.

[0065] In this embodiment, the recommended method for railway bridge pile foundation includes the following steps:

[0066] Step S10: Obtain the pile foundation configuration type database.

[0067] It should be noted that the pile foundation configuration type database is a pre-established database of pile foundation configuration types.

[0068] It is understood that the pile foundation configuration type database is used to obtain recommended target pile foundation configurations from it through a recommendation algorithm.

[0069] In the specific implementation, after storing the pile foundation configuration type and bridge configuration type into the database, the pile foundation configuration type database and its data structure are obtained.

[0070] Step S20: Determine whether to use the recommendation algorithm to recommend the foundation pile configuration or the default foundation pile configuration.

[0071] It should be noted that the recommendation algorithm selects pile foundation configurations that meet the rules from the pile foundation configuration types recorded in the pile foundation configuration type database according to the corresponding preset rules.

[0072] It is understood that the default pile configuration is the pile configuration used uniformly when no recommendation algorithm is used. It can be the pile configuration that is used most frequently in the pile configuration type database. This implementation does not impose specific restrictions on this.

[0073] Furthermore, the recommendation algorithm includes at least: the most-call recommendation algorithm, the most economical recommendation algorithm, the environment-adaptive recommendation algorithm, the nearest-neighbor consistency recommendation algorithm, and the comprehensive recommendation algorithm.

[0074] Step S30: When using a recommendation algorithm, obtain the algorithm library and obtain the recommendation algorithm and corresponding rules from the algorithm library.

[0075] It should be noted that the algorithm library is a database of recommendation algorithms and their corresponding rules. Various recommendation algorithms are developed and maintained according to business needs.

[0076] It is understandable that all recommendation algorithms in the algorithm library are required to inherit the same interface and establish a unified scheduling method.

[0077] In the specific implementation, a filtering method is added to the corresponding recommendation algorithm class. The filtering logic is implemented using the corresponding ORM framework of the database (such as the Link framework in C# or the MyBatis framework in Java), and the filtering results from the database are returned, thereby realizing the function.

[0078] Step S40: Filter the pile foundation configurations recorded in the pile foundation configuration type database according to the corresponding rules of the recommendation algorithm to obtain the filtering results.

[0079] It should be noted that the corresponding rule of the recommendation algorithm is the recommendation method in the recommendation algorithm.

[0080] In specific implementations, the corresponding rules of the recommendation algorithm include at least the following: Most frequently used recommendation algorithm: Recommending the most frequently used basic type from the basic configuration library under the same conditions; Most economical recommendation algorithm: Recommending the scheme with the least material usage or the lowest overall unit price from the basic configuration library under the same conditions; Environmental adaptation recommendation algorithm: Recommending the most frequently used basic type from the basic configuration library under the same environmental conditions; Proximity consistency recommendation algorithm: Recommending the same or similar basic type as the neighboring piers from the basic configuration library under the same environmental conditions; Comprehensive recommendation algorithm: Combining the above-mentioned most favored recommendation algorithm, most economical recommendation algorithm, etc., and setting different weights to form a comprehensive evaluation rule, selecting the basic configuration type from the basic configuration library that matches the comprehensive evaluation rule under the same environmental conditions.

[0081] It is understood that the common scenario types for the rules corresponding to the environment adaptation recommendation algorithm include: plains, rugged mountains, hilly areas, urban areas, soft soil areas, earthquake areas, etc., which can be added as needed. This implementation does not impose specific restrictions on this.

[0082] It is worth understanding that the number of neighboring piers can be set in the rules of the neighbor consistency recommendation algorithm according to user requirements, and this implementation does not impose specific restrictions on this.

[0083] Further, the step of filtering the pile foundation configurations recorded in the pile foundation configuration type database according to the corresponding rules of the recommendation algorithm to obtain the filtering results includes: adding filtering labels to the data structure of the pile foundation configuration type database; selecting filtering labels and inputting corresponding filtering conditions; performing structured query language filtering according to the filtering conditions and the corresponding rules of the recommendation algorithm combined with the number of times the database records are called, to obtain pile foundation configurations that meet the filtering conditions and use them as filtering results.

[0084] It should be noted that the filtering labels are used to filter out the type of pile foundation configuration based on the attributes of the pile foundation configuration.

[0085] In the specific implementation, filter tags are extracted based on the attributes of the pile foundation configuration and associated with the pile foundation configuration in the pile foundation configuration type database. Filter tags are selected in conjunction with the project requirements and the corresponding filter conditions are entered for filtering.

[0086] Step S50: Use the valid results from the screening results as the target recommended pile foundation configuration to complete the recommendation of railway bridge pile foundations.

[0087] It should be noted that the valid results in the screening results are those that meet the engineering requirements among the selected pile configurations.

[0088] It is understood that the target recommended pile foundation configuration is the final pile foundation configuration to be adopted.

[0089] In the specific implementation, the initial foundation scheme corresponding to each result is obtained based on the screening results, it is determined whether it meets the engineering requirements, the result that meets the requirements is determined as the valid result, and it is used as the target pile foundation configuration.

[0090] Furthermore, in order to improve the accuracy of algorithm recommendations, the algorithm library needs to be maintained. After step S50, the algorithm library is further maintained by: optimizing the rules of the recommendation algorithm through parameter optimization and adding custom recommendation algorithms according to user needs.

[0091] It should be noted that the parameter optimization is a method to achieve the design goal. By parameterizing the design goal and using optimization methods, the design variables are continuously adjusted so that the design result continuously approaches the parameterized target value. For example, for the recommendation algorithm that is called the most, the number of times it is used is optimized. This implementation does not impose specific restrictions on this.

[0092] like Figure 3 As shown, Figure 3This is a schematic diagram of the module function matrix. The diagram includes: a rule definition module for unified naming, storing pile parameters, pile classification, type illustrations, etc.; an algorithm configuration module for setting default settings, user preferences, default recommendations, priority rules, etc.; an engineering case library for extracting project information, railway grade, bridge information, pile foundation cases, load types, etc.; an algorithm design module for algorithm design and management, including built-in algorithms such as the most frequently called recommendation algorithm, the most economical recommendation algorithm, and the environmentally adaptive recommendation algorithm; and a foundation type configuration library containing bridge and pile foundation configuration information, such as 32m simply supported beams, 48m continuous beams, 180° continuous arches, 8-1.0m pile group foundations, and 12-1.0m pile group foundations.

[0093] like Figure 4 As shown, Figure 4 This is a schematic diagram of the overall process of the railway bridge pile foundation recommendation method in this embodiment. Upon entering the algorithm entry point, filtering conditions are obtained based on the scheme design. The filtering conditions are then entered for querying. Before obtaining the filtering conditions based on the scheme design, the scheme design is obtained by calling the bridge foundation library through the geometry engine. When manual selection is selected, the recommendation algorithm is used, querying the pile foundation configuration library to obtain recommended pile foundation configurations. When manual selection is not used, the default configuration algorithm is used. The default configuration algorithm is set by querying the pile foundation configuration library in conjunction with the recommendation algorithm. Before selecting the recommendation algorithm, the algorithm design needs to be combined with the experience case library and rule definitions.

[0094] As shown in Tables 1-9, Tables 1-9 are the commonly used pile foundation layouts statistically compiled from the experience case database. Table 3 is the layout table for Φ1.0m pile foundations, Table 4 is the layout table for Φ1.25m pile foundations, Table 5 is the layout table for Φ2.0m pile foundations, Table 6 is the layout table for Φ2.2m pile foundations, Table 7 is the layout table for Φ2.5m pile foundations, Table 8 is the layout table for Φ2.8m pile foundations, and Table 9 is the layout table for Φ3.0m pile foundations.

[0157] This embodiment filters the pile foundation configurations recorded in the pile foundation configuration type database according to the recommendation algorithm and corresponding rules, and obtains the target recommended pile foundation configuration based on the filtering results. This simplifies the process of determining the pile foundation configuration, improves engineering efficiency, saves time and costs, and enhances safety.

[0158] refer to Figure 5 , Figure 5 This is a flowchart illustrating the second embodiment of the railway bridge pile foundation recommendation method of the present invention. Based on the first embodiment described above, the second embodiment of the railway bridge pile foundation recommendation method of the present invention is proposed.

[0159] In this embodiment, before step S10, the method further includes:

[0160] Step S01: Obtain the naming rules for pile foundations, the classification rules for pile foundations, the naming rules for bridges, and the classification rules for bridges.

[0161] It should be noted that the pile foundation naming rules are the pile foundation naming methods. For example, 8-1.0m and 10-1.25m respectively represent 8 pile foundations with a diameter of 1m and 10 pile foundations with a diameter of 1.25m, etc. The pile foundation classification rules are the pile foundation classification methods, such as friction piles, columnar piles, etc. This implementation does not impose specific restrictions on them.

[0162] It is understood that the bridge naming rules are bridge naming methods, such as simply supported beams, continuous beams, etc., and the bridge classification rules are bridge classification methods, such as double-track, single-track, etc. This implementation does not impose specific restrictions on them.

[0163] Step S02: Combine and arrange the pile diameter, layout type and number of piles to form different types of pile configuration types.

[0164] As shown in Table 25, the table shows the pile foundation configuration types, including information such as pile foundation name, pile foundation parameters, pile foundation classification, and layout type.

[0165] Table 25

[0166]

[0167] It should be noted that commonly used pile diameters are 1.0m, 1.25m, 1.5m, 2.0m, 2.5m, and 3.0m, and this implementation does not impose specific restrictions on them.

[0168] It is worth noting that commonly used pile arrangement types include row and column, quincunx, etc. Figures 6a-6b As shown, Figure 6a This is a schematic diagram of a row-and-column pile foundation layout. Figure 6b This is a schematic diagram of the plum blossom-shaped pile foundation layout type. Custom settings are also possible, but this implementation does not impose specific restrictions on this.

[0169] Understandably, the commonly used number of piles for foundations is 8, 9, 10, 11, 12, 16, etc., and this implementation does not impose specific restrictions on this.

[0170] In practical implementation, different types of pile foundation configurations are formed by combining and arranging the pile diameter, layout type, and number of piles. Examples include: a quincunx arrangement of 10 piles with a diameter of 1.0m; a row-and-column arrangement of 9 piles with a diameter of 1.0m; a row-and-column arrangement of 8 piles with a diameter of 1.0m; a quincunx arrangement of 8 piles with a diameter of 1.0m; a quincunx arrangement of 11 piles with a diameter of 1.0m; and a row-and-column arrangement of 12 piles with a diameter of 1.0m, etc. Figures 7a-7f As shown, Figure 7a This is a schematic diagram of a quincunx arrangement of 10 piles, each 1.0m in diameter. Figure 7b This is a schematic diagram of a row-and-column pile foundation configuration consisting of nine piles, each with a diameter of 1.0m. Figure 7c This is a schematic diagram of a row-and-column pile foundation configuration with 8 piles, each 1.0m in diameter. Figure 7d This is a schematic diagram of a quincunx arrangement of 8 piles, each with a diameter of 1.0m. Figure 7e This is a schematic diagram of a quincunx arrangement of 11 piles, each with a diameter of 1.0m. Figure 7f This is a schematic diagram of a row-and-column arrangement of 12 piles with a diameter of 1.0m. This implementation does not impose specific restrictions on this arrangement.

[0171] Step S03: Enter the pile foundation configuration type into the database according to the pile foundation naming rules and the pile foundation classification rules.

[0172] It is understandable that the pile foundation configuration types are named and classified according to the pile foundation naming rules and the pile foundation classification rules before being entered into the database.

[0173] Step S04: Extract project type, beam structure, pier height, and pier location information from the engineering case library.

[0174] It should be noted that the engineering case library is a database of bridge schemes for existing projects. The engineering case library is established by statistically analyzing and storing the basic configurations of bridge schemes for existing projects.

[0175] It is understandable that the data structure of the engineering case library contains key information affecting pile foundation design, such as project information, railway grade, load type, bridge pier height, beam type, and foundation configuration type.

[0176] Step S05: Determine the bridge configuration type based on the project type, beam structure, pier height, and pier location information.

[0177] As shown in Table 26, Table 26 is the bridge configuration type, which includes information such as pier height, beam type, main span, span arrangement, and foundation type.

[0178] It should be noted that the beam structure includes T-shaped rigid frames, continuous steel structures, etc., and the pier height includes 5m to 10m, 10m to 15m, 15m to 20m, etc. This implementation does not impose specific restrictions on these.

[0179] Step S06: Enter the bridge configuration type into the database according to the bridge naming rules and the bridge classification rules.

[0180] It is understandable that the bridge configuration types are named and classified according to the bridge naming rules and the bridge classification rules before being entered into the database.

[0181] Step S07: Establish a pile foundation configuration type database based on the pile foundation configuration type and bridge configuration type after they have been entered into the database.

[0182] Table 26

[0183]

[0184]

[0185] It is understandable that after the pile foundation configuration type and bridge configuration type are entered into the database, the bridge foundation type is mapped to the entered pile foundation configuration type to obtain the pile foundation configuration type database, such as... Figure 8 As shown, Figure 8 This is a schematic diagram of the pile foundation configuration type database. The diagram includes information such as beam type, main span, span arrangement, foundation type, number of calls under normal conditions, number of calls under a certain scenario, label A, label B, and notes.

[0186] Furthermore, in order to make the configuration of the pile foundation configuration type database more accurate, step S07 includes: obtaining the correspondence between bridge pier height and foundation type in the bridge configuration type; and according to the relevant factors of the bridge and the project and the correspondence, matching the foundation type of the bridge to the pile foundation configuration type after it is entered into the database, thereby obtaining the pile foundation configuration type database.

[0187] It should be noted that the bridge configuration types include side piers and center piers. Side piers refer to piers with expansion joints on the bridge deck, while center piers refer to piers without expansion joints on the bridge deck.

[0188] It is understandable that by mapping the bridge's foundation type to the pile foundation configuration type after it has been entered into the database, a mapping relationship can be obtained. When filtering based on the filter tags, the corresponding pile foundation configuration type can be accurately selected.

[0189] This embodiment establishes a pile foundation configuration type database by storing the pile foundation configuration types and bridge configuration types into a database, thereby creating a mapping relationship and facilitating accurate filtering of the corresponding pile foundation configuration type when using filtering tags.

[0190] refer to Figure 9 , Figure 9 This is a flowchart illustrating the third embodiment of the railway bridge pile foundation recommendation method of the present invention. Based on the first embodiment described above, the third embodiment of the railway bridge pile foundation recommendation method of the present invention is proposed.

[0191] In this embodiment, after step S30, the method further includes:

[0192] Step S301: Determine whether to choose a recommendation algorithm yourself or use the default recommendation algorithm.

[0193] It should be noted that the default recommendation algorithm is the initial algorithm when no algorithm selection is performed. Different default recommendation algorithms can be formulated according to different projects and different users.

[0194] In the specific implementation, a default rule configuration file for the algorithm is formulated. When using the default recommendation algorithm, a mapping file between bridge pier height and foundation type is established. Based on project characteristics and bridge scheme and other relevant factors, the pile foundation configuration for different bridge pier mappings is selected in combination with the default rules, and the pile foundation configuration is saved to the corresponding foundation configuration table in the project library to obtain the initial foundation scheme.

[0195] It is understandable that the algorithm's default rule configuration file includes a configuration of whether to prioritize the default, the project, or the user.

[0196] Step S302: When selecting a recommendation algorithm, obtain the pile foundation configurations in the pile foundation configuration database that conform to the rules corresponding to the recommendation algorithm, based on the selected recommendation algorithm, as the filtering results.

[0197] It is understandable that when choosing a recommendation algorithm, one can choose from the most frequently called recommendation algorithm, the most economical recommendation algorithm, the environment-adaptive recommendation algorithm, the nearest-neighbor consistency recommendation algorithm, and the comprehensive recommendation algorithm. This implementation does not impose specific restrictions on this.

[0198] Step S303: Save the pile foundation configuration to the corresponding foundation configuration table in the project library to obtain the initial foundation scheme.

[0199] It should be noted that the project library is a database of engineering projects, and the project library contains a basic configuration table.

[0200] Step S304: Determine whether the initial foundation scheme meets the engineering requirements for each pier.

[0201] It is understandable that determining whether the initial foundation scheme meets the project requirements for each pier can be done by judging whether the pile foundation configuration in the initial foundation scheme is within the preset range of the project or whether it meets the preset value or preset type, etc. This implementation does not impose specific restrictions on this.

[0202] Step S305: When the initial basic scheme meets the engineering requirements, the initial basic scheme that meets the design requirements is saved.

[0203] It is understandable that when the initial foundation scheme meets the engineering requirements, that is, the pile foundation configuration in the initial foundation scheme is a valid result, the scheme is saved.

[0204] Step S306: Determine the corresponding pile foundation configuration as a valid result in the screening results.

[0205] It is understandable that when there is only one initial foundation scheme that meets the engineering requirements, the pile foundation configuration in the scheme is determined as a valid result in the screening results, and the result is used as the target recommended pile foundation configuration. When there is more than one initial foundation scheme that meets the engineering requirements, the pile foundation configurations in the initial foundation schemes are each taken as valid results, and the final result used as the target recommended pile foundation configuration is determined from them.

[0206] Furthermore, after determining whether the initial foundation scheme meets the engineering requirements for each pier, the method further includes: when the initial foundation scheme does not meet the engineering requirements, optimizing and modifying the foundation scheme that does not meet the design requirements to form a new initial foundation configuration scheme; recording the number of times this type of pile foundation is used under the same conditions as a preset value and saving it to the database.

[0207] It should be noted that optimizing and modifying the foundation scheme that does not meet the design requirements may refer to modifying the parts of the foundation scheme where the pile foundation configuration does not conform to the engineering requirements.

[0208] It is understood that the initial value of the number of uses can be generated and recorded automatically, such as once or twice, and this implementation does not impose any specific restrictions on this.

[0209] In this embodiment, an initial foundation scheme is obtained by saving the pile foundation configuration that conforms to the rules corresponding to the recommendation algorithm to the pile foundation configuration table in the project library. The validity of the pile foundation configuration is determined by judging whether the scheme meets the engineering requirements.
