Description

Technical Field

[0001] This invention relates to the fields of bridge design and computer technology, and in particular to an integrated digital design system and method for bridge superstructure and substructure. Background Technology

[0002] Bridges, as a crucial component of transportation infrastructure, play a vital role in promoting regional economic development and improving transportation efficiency. Bridge design must consider not only the functionality and safety of the structure but also its economic viability, aesthetics, and environmental impact. In bridge design, the substructure design is a key element in ensuring the overall stability and durability of the bridge.

[0003] Currently, parametric modeling in bridge substructure calculation software is cumbersome and lacks optimization functions for components and structural systems, causing numerous inconveniences for bridge designers. The main shortcomings are as follows:

[0004] (1) Importing routes (vertical curves, horizontal curves, etc.) requires extracting the route dwg / dxf files from CAD and then importing them into the analysis software;

[0005] (2) Importing geological parameters is troublesome, the amount of data is large and prone to errors (soil layers and thickness, pile location, and borehole information cannot be automatically matched).

[0006] (3) The lower structure has many parameters, which makes modeling time-consuming and inefficient. It is usually necessary to select representative locations for calculation and cannot perform batch calculation and analysis.

[0007] (4) The upper and lower structures are modeled and analyzed separately, which is not detailed enough;

[0008] (5) The parameters have poor linkage, and multiple parameters need to be modified when optimizing and adjusting the design; including individual component parameters (pier height, spacing, tie beam arrangement, foundation embedment depth, etc.) and related parameters of the upper and lower structures.

[0009] With the development of modern engineering technology, traditional design methods can no longer meet the ever-increasing requirements for design accuracy and efficiency.

[0052] The advantages of this invention are:

It creates a parametric design system using computer programming technology, enabling intelligent modeling of bridge superstructure and superstructure, one-click generation of finite element analysis models, and one-click output of calculation reports. The system mainly consists of three databases and three functional modules: a parameter database, a superstructure model database, a substructure model database, a route identification module, a geological parameter identification module, and an integrated intelligent analysis module. The implementation method involves classifying and refining the design parameters of the bridge superstructure and superstructure to form a universal modular parameter input system.

[0073] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0074] Example 1

[0075] like Figure 2 and Figure 3 As shown, the present invention provides an integrated digital design system for the superstructure and superstructure of a bridge, comprising: three databases and three functional modules, namely a parameter database, a superstructure model database, a substructure model database, a route identification module, a geological parameter identification module, and an integrated intelligent analysis module.

[0076] The parameter database is used to store user-inputted project information, route information parsed by the route recognition module, geological information parsed by the geological parameter recognition module, upper and lower templates created by the user or imported by matching the upper and lower model databases, and user-inputted bridge information.

[0077] Specifically,

[0078] Project information includes basic project information, as well as information on materials, loads, and specifications;

[0079] The route information is obtained by importing route files generated by route design software (such as Weidi software) and parsing them through the route recognition module. The parameters include horizontal curves, vertical curves, ground lines, superelevation, and other information.

[0080] Geological information is the design parameters obtained by importing geological files (such as geological drawings in dwg format) generated by geological design software (such as Lizheng software) and parsing them through the geological parameter recognition module. These parameters include information such as boreholes, soil layers, and station numbers.

[0081] The upper template is created by the user or matched and imported from the upper model database by the integrated intelligent analysis module. Users can adjust the required parameters according to their needs and then store them in the parameter database, including parameters such as support height, number of bridge spans, and edge distance.

[0082] The lower template is created by the user or matched and imported from the lower model database by the integrated intelligent analysis module. Users can adjust the required parameters according to their needs and then store them in the parameter database, including parameters such as cap beams, piers, piles, and tie beams.

[0083] Bridge information includes span arrangement, cross-sectional arrangement, pier height, pile length, and other information.

[0084] The parameters stored in the parameter database are divided into primary parameters and secondary parameters. Primary parameters are those read from different files, while secondary parameters are related parameters calculated and correlated based on the primary parameters, and can be directly used for design calculations. Project information, route information, geological information, and bridge information are primary parameters; upper formwork and lower formwork are secondary parameters.

[0085] The superstructure model database and the substructure model database are standard model files and corresponding model summary information built based on standard drawings of the superstructure and substructure of existing bridges. The superstructure model database stores the user's existing standard model files for the superstructure, along with their corresponding model summary information. The substructure model database stores the user's existing standard model files for the substructure, along with their corresponding model summary information.

[0086] The route recognition module is a program module developed based on the C++ language. It directly parses the design parameters in the route file (the route file output by the Weidi software) and reads horizontal curve data, vertical curve data, ground line data, and superelevation data into the program, which can be directly called in the subsequent design stage, greatly improving the speed and efficiency of the program.

[0087] Identifying horizontal curves includes: the starting point of the route (coordinates, station number, direction); and the various line shapes that make up the horizontal curve, including straight lines (length), circular arcs (length, direction, radius), and transition curves (length, direction, radius, parameter A).

[0088] Identifying vertical curves includes: the number of points that make up the vertical curve, the station number, elevation, and radius of each point.

[0089] The identification of the ground line includes: the number of points that make up the ground line, the station number and elevation of each point.

[0090] Superelevation identification includes: superelevation of the left lane and superelevation of the right lane; the number of points constituting superelevation of the left lane, the station number and slope of each point; the number of points constituting superelevation of the right lane, the station number and slope of each point.

[0091] In this embodiment, the route recognition module is developed using the C++ standard library. It uses the `std::ifstream` class template to read data files, the `std::string` class template to store data, and the `std::vector` class template to store arrays. The route recognition module can read route files output by the Weidi software, automatically parse the design parameters in the route files, and read horizontal curve data, vertical curve data, ground line data, and superelevation data into the parameter database. The pure virtual function class `IDaolu` unifies the reading interface for all route files. The simple factory design pattern is used to create various route file reading interfaces, facilitating direct calls in subsequent design stages and avoiding repetitive input.

[0092] The geological parameter identification module is a program module developed based on the C++ language. It directly parses the design parameters in the geological file (the geological file output by the Lizheng software) and reads the survey data such as soil layers, station numbers, and boreholes into the program, which can be directly called in the subsequent design stage, greatly improving the speed and efficiency of the program.

[0093] The geological parameter identification module includes CAD file identification, exploration well table database, data table identification, parameter identification, and data merging. The specific processing steps are as follows:

[0094] CAD file (dwg format geological drawings) recognition refers to: reading various types of CAD elements from CAD files, including lines (starting point coordinates, ending point coordinates), arcs (center coordinates, radius, starting point angle, ending point angle), circles (center coordinates, radius), polylines (number of points, coordinates of points, convexity of points), text (position, content, character height), multiline text (position, content, character height), blocks (elements within blocks), etc.

[0095] The borehole table database stores various types of borehole tables. The main parameters include the type of borehole (drill hole), the size of the table, the area where each parameter is located, the data format of each parameter, and the type of each parameter. Each parameter refers to information such as the soil layer and thickness distribution of the borehole.

[0096] Data table recognition refers to: reading individual table parameters (table width, height) from the borehole table database, matching the dimensions (table width, height) from CAD elements, saving the coordinates and dimensions of the CAD elements after a successful match, and saving the type of the matched borehole table (different for each type of borehole table).

[0097] Parameter identification refers to: accurately calculating the coordinates of each parameter (the cell containing each data in the table) based on the type and size of the borehole table; matching the coordinates with the CAD file; and parsing the parameter values ​​corresponding to the CAD elements after matching them.

[0098] Data merging refers to the process where an exploration well consists of one or more tables. If there are multiple tables, the parameters of the multiple tables need to be merged before input. Tables with the same name are filtered out and then sorted according to page number.

[0099] In this embodiment, the geological parameter recognition module is developed using the C++ standard library. It uses the `std::ifstream` class template to read data from DXF files, the `std::string` class template to store DXF data, the `std::vector` class template to store arrays, and the `std::map` class template to store mapping data. The geological parameter recognition module can read exploration data from geological survey result files (geological files output by the Lizheng software) and automatically recognize CAD file elements, including lines, arcs, circles, polylines, text, multiline text, blocks, etc. It then parses the parameters corresponding to these elements to form a complete geological survey data table, which is displayed in real-time on the platform interface. This data can be automatically converted into later modeling parameters and stored in the parameter database for easy direct access in subsequent design stages, avoiding repetitive input. JSON format is used as the configuration file. The development utilizes the open-source JSON library provided by nlohmann.

[0100] The integrated intelligent analysis module automatically matches suitable upper and lower models from the upper and lower model databases based on bridge and route information, generates corresponding upper and lower templates, stores them in the parameter database, and combines them into a full bridge geometric model.

[0101] The integrated intelligent analysis module is a program module developed based on the C++ language. Based on the information input by the user and the information read from the route and geological files, it uses intelligent algorithms to complete the work of searching the superstructure, arranging the main beam, arranging the substructure, searching for boreholes, combining them into a full bridge geometric model, and generating a finite element analysis model with one click.

[0102] In this embodiment, the integrated intelligent analysis module uses the fine-grained model generation function of the upper and lower structure provided by WISEPLUS software to generate XML finite element analysis model data format supported by WISEPLUS software, export it to WISEPLUS software, generate finite element analysis model, and perform calculations using the finite element analysis model calculation function provided by WISEPLUS software. The calculation report is automatically generated using the standard design function provided by WISEPLUS software.

[0103] This invention provides an integrated digital design system for bridge superstructure and superstructure, which can achieve:

[0104] Bridge route data is automatically read into latitude and longitude data, including horizontal curves, vertical curves, superelevation, etc., and after parsing, it is directly used in the finite element analysis model, reducing user access and input work;

[0105] Geological survey data is automatically read from Lizheng data, including borehole information, soil layer distribution information, etc. After parsing, it is directly used for finite element analysis models and component verification. At the same time, it can intuitively display the information of each pile position on the route, which is convenient for users to view and check, reduces the workload of copying data for modeling and verification, and improves accuracy.

[0106] Based on existing standard diagrams, an upper model database and a lower model database are formed. By calling the model database, a model matching the upper and lower structures can be directly generated for analysis and calculation.

[0107] When modifying component parameters in the model, the system can automatically associate the data of mutually affecting components, enabling parameter association of the entire structure above and below based on design rules. This reduces the workload of designers and avoids errors such as omissions in modification.

[0108] It can perform batch calculations and analyses on all substructures along the entire route at once, improving efficiency while avoiding the one-sidedness of selecting representative structures for verification based on experience in previous designs.

[0109] Example 2

[0110] like Figure 1 As shown in Embodiment 1 above, this invention provides a design method for an integrated digital design system for bridge superstructures. Taking a "25-meter span prefabricated small box girder / double-column pier" as an example, the specific process of the integrated digital design method for bridge structures is as follows:

[0111] Step 1: Input bridge design parameters.

[0112] Users input project information (project name = highway bridge, seismic acceleration = 0.05g, material = C50, etc., design specification = "General Specifications for Highway Bridge and Culvert Design", etc.) in the system operation interface, import route files (k.pm, k.zdm, k.dmx, k.sup), import geological files (zdm.dwg), and input bridge information (bridge name = mainline bridge, route = k, starting chainage = 58134.391, span arrangement = ((3×25), (4×25), (4×25), (3×30)), cross section = roadbed width = 26.5m, bridge width = 2×12.75m, lane type = left lane).

[0113] After parsing the route file and geological file, the system obtains route information and geological information and stores it in the parameter database;

[0114] In this embodiment, a schematic diagram of inputting bridge information in the system operation interface is shown, as follows: Figure 4 As shown.

[0115] Step 2: Search for the upper model to generate the upper structure.

[0116] The system calls the span arrangement in the bridge information in the parameter database to obtain the bridge width and span arrangement, thereby obtaining the number of spans and span of each bridge section. Based on these parameters, a suitable superstructure model can be matched for each bridge section from the superstructure model database.

[0117] In this embodiment, a schematic diagram of a certain section (span arrangement 4×25m) in the superstructure is shown below. Figure 5 As shown.

[0118] Step 3: Arrange the main beams.

[0119] Based on the span arrangement of each bridge section, the system calls the horizontal curve information in the route information and the station information in the geological information in the parameter database to calculate the actual position of the bridge on the route, as well as the coordinates, normal direction and other parameters at each actual position.

[0120] Step 4: Search for the lower model to generate the lower structure, and arrange the lower structure.

[0121] After the main beams are arranged, the station numbers at the spans can be calculated. Based on the station numbers, route information (vertical curve elevation, ground line elevation) is retrieved from the parameter database, and the height of the superstructure is retrieved from the upper template in the parameter database to obtain the total height of the piers and cap beams. Based on the total height and the width of the superstructure, a suitable lower structure is matched from the lower model database to generate the lower structure. Based on the correspondence between the normal direction at the station number and the positions of the superstructure and lower structure, the lower structure is arranged.

[0122] In this embodiment, a schematic diagram of the pier parameter list in the substructure is shown below. Figure 6 As shown, the pier parameter list details the pier height, foundation depth, and pile length for each bridge section.

[0123] Step 5: Search for boreholes.

[0124] Once the substructure is laid out, the pile coordinates can be obtained. Geological information (corresponding to the borehole information of the route) can be retrieved from the parameter database, and the borehole (exploration borehole) information closest to the laid-out pile location can be found based on the pile coordinates.

[0125] In this embodiment, a schematic diagram of the borehole list in the system operation interface is shown below. Figure 7 As shown.

[0126] Step 6: Assemble the full bridge geometric model.

[0127] After completing the layout of the superstructure and the substructure, the connection relationship between the substructure and the superstructure can be determined, thus forming a full bridge geometric model.

[0128] In this embodiment, the connection diagram between the lower structure and the upper structure, i.e., the schematic diagram of the full bridge geometric model, is shown below. Figure 8 As shown.

[0129] Step 7: Form a finite element analysis model.

[0130] First, a refined finite element analysis model of the superstructure is generated, then a refined finite element analysis model of the substructure is generated, and finally, based on the connection relationship between the superstructure and the substructure, the superstructure model and the substructure model are merged into a complete finite element analysis model.

[0131] In this embodiment, a schematic diagram of the finite element analysis model is shown below. Figure 9 As shown.

[0132] Step 8: Standardize the design.

[0133] According to the specifications, calculate whether the reinforcement of the piles meets the requirements, and calculate whether the configuration of the piers meets the requirements.

[0134] Step 9: Generate a calculation report.

[0135] The bridge's design data and detailed specifications are output into a Word document in the form of pictures, text, and tables to form the final calculation report.

[0136] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
