[0002] With the explosion of BIM (Building Information Modeling) technology, GIS (geographic information system) and artificial intelligence technology based on deep neural networks, engineers develop a new generation of intelligent bridge design system based on digital twin, which integrates BIM technology, GIS technology and artificial intelligence technology, hoping to show the bridge BIM model through the GIS system scene, quickly construct the bridge overall scheme and bridge structure scheme by using the artificial intelligence paradigm, show the relationship between the three-dimensional bridge scheme and the surrounding landforms in the geographical and geological scene, provide a complete information decision environment and intuitive scheme effect for the designers and decision makers of the scheme, and then improve the design quality and decision efficiency of the bridge scheme, and meet the new needs of engineering design in the artificial intelligence era. As we all know, the explosion of this artificial intelligence technology is mainly due to the three factors of data, algorithm and computing power. The effect and technical maturity of artificial intelligence technology based on deep neural networks depend on the topological form of deep neural networks, the scale of model parameters, the scale and quality of data samples and other factors.

[0077] 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.

[0078] Reference Figure 1 , Figure 1 This is a schematic diagram of the equipment structure for rapidly constructing bridge solution datasets based on a GIS system, which is part of the hardware operating environment involved in the embodiments of the present invention.

Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0080] Those skilled in the art will understand thatFigure 1 The structure shown in the figure does not constitute a limitation on the GIS system-based bridge scheme data set rapid construction device, and can include more or fewer components than the figure, or combine certain components, or different component arrangements.

[0081] As shown in Figure 1 The memory 1005 as a storage medium can include an operating system, a network communication module, a user interface module, and a GIS system-based bridge scheme data set rapid construction program.

[0082] In the GIS system-based bridge scheme data set rapid construction device shown in Figure 1 The network interface 1004 in the GIS system-based bridge scheme data set rapid construction device is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the GIS system-based bridge scheme data set rapid construction device can be arranged in the GIS system-based bridge scheme data set rapid construction device, and the GIS system-based bridge scheme data set rapid construction device calls the GIS system-based bridge scheme data set rapid construction program stored in the memory 1005 through the processor 1001, and executes the GIS system-based bridge scheme data set rapid construction method provided in the embodiment of the application.

[0083] The embodiment of the application provides a GIS system-based bridge scheme data set rapid construction method, which refers to Figure 2 , Figure 2 The flowchart of the first embodiment of the GIS system-based bridge scheme data set rapid construction method of the application.

[0084] In this embodiment, the GIS system-based bridge scheme data set rapid construction method comprises the following steps:

[0085] Step S10: When designing a bridge, GIS environment data and interface data provided by related upstream and downstream professionals are obtained through a GIS system.

[0086] It should be noted that the execution subject of the embodiment is an intelligent bridge design system for constructing a bridge scheme data set, and can also be other devices or systems that can achieve the same or similar functions, and the embodiment does not limit this. The embodiment takes the intelligent bridge design system for constructing a bridge scheme data set as an example for description, and the intelligent bridge design system is an intelligent design system integrating BIM, GIS and AI. The intelligent bridge design system integrates BIM technology, GIS technology and artificial intelligence technology.

[0087] It can be understood that when the bridge design is performed, the GIS environment data and the interface data can be obtained by using a GIS system, the GIS system can be ArcGIS, Skline, Supermap and other GIS software, and can also be other systems or software with basic interactive functions such as drawing points, lines and surfaces, and the embodiment does not limit this.

[0088] It should be understood that the intelligent bridge design system is composed of a BIM model library module, a GIS environment module, a scheme automatic / intelligent decision module, a database management module and other professional interface modules. The GIS environment module provides a GIS scene for a new generation of intelligent bridge design system, mainly including management and rendering functions of geographic and geological data. The GIS environment module provides environmental data of geographic and geological elements, and is also a host system environment of other professional interface modules. The scheme automatic / intelligent decision module is mainly used to complete the decision of the bridge scheme. The database management module mainly functions in the management and storage of GIS system data. The other professional interface modules are mainly used to manage the interface data provided by upstream and downstream professionals. Therefore, the GIS environment data and the interface data can be obtained by using the GIS system. The upstream and downstream professional interface data mainly includes line schemes provided by line professionals, station schemes provided by station professionals, regional geological information provided by geological professionals and other interface data.

[0089] Step S20: obtaining control element information and ground line information based on the GIS environment data and the interface data.

[0090] In specific implementation, the control element information and the ground line information can be obtained by analyzing the GIS environment data and the interface data, and the bridge scheme design based on the preset bridge automatic decision algorithm is prepared.

[0091] Step S30: performing bridge scheme design based on the control element information and the ground line information by using the preset bridge automatic decision algorithm, and generating bridge scheme information.

[0092] It should be understood that the preset bridge automatic decision algorithm is a traditional business rule bridge automatic decision algorithm, and the bridge scheme can be designed by using the traditional business rule bridge automatic decision algorithm, the control element information and the ground line information, and the bridge scheme is generated.

[0093] Optionally, after the bridge scheme design is performed and the bridge scheme is generated, the method further includes: obtaining bridge scheme business rules, control element models and topographic and geomorphic data; auditing the bridge scheme according to the bridge scheme business rules, the control element models and the topographic and geomorphic data; when the bridge scheme does not conform to one or more of the bridge scheme business rules, the control element models and the topographic and geomorphic data, returning to the step of obtaining the GIS environment data and the interface data by using the GIS system, and redesigning the bridge scheme.

[0094] It should be noted that the bridge scheme business rule is a standard rule to be followed in the bridge design process, and the control element model and the topographic and geomorphic data are data collected in the actual road conditions. By one-to-one comparison of the data in the generated bridge scheme with the bridge scheme business rule, the control element model and the topographic and geomorphic data, the bridge scheme is audited to determine whether the bridge scheme meets the requirements.

[0095] In specific implementation, if some data in the bridge scheme does not comply with one or more of the bridge scheme business rule, the control element model or the topographic and geomorphic data, the audit is not passed, and the bridge scheme needs to be redesigned. Therefore, the step of obtaining GIS environment data and interface data through the GIS system is returned, so as to redesign the bridge scheme, and obtain a bridge scheme that meets the requirements of the bridge scheme business rule, the control element model and the topographic and geomorphic data.

[0096] Step S40: Analyzing the influencing factors affecting the bridge scheme based on the bridge scheme and collecting the influencing factor data.

[0097] It should be noted that when the bridge scheme is generated, the bridge scheme can be analyzed to determine the influencing factors affecting the bridge scheme and collect the influencing factor data.

[0098] In specific implementation, the influencing factors affecting the bridge scheme include line element information, control element information, topographic element information and geological element information, and other influencing factors can also be included. This embodiment is not limited thereto, and this embodiment is described by taking the line element information, the control element information, the topographic element information and the geological element information as examples.

[0099] Step S50: Constructing a bridge scheme data set of the bridge scheme and the influencing factor data, storing the bridge scheme data set in a bridge scheme database, and completing the construction of the bridge scheme data set.

[0100] It should be understood that when the bridge scheme is determined and the influencing factor data affecting the bridge scheme is collected, a bridge scheme data set of the bridge scheme and the influencing factor data can be constructed based on the bridge scheme and the influencing factor data, and the bridge scheme data set is stored in a bridge scheme database. The bridge scheme database stores the standardized bridge scheme data set, so that the bridge scheme and the influencing factor data affecting the bridge scheme can be obtained by querying the bridge scheme database. The bridge scheme data set is stored in the database by calling the database management class module.

[0101] Optionally, the specific step of constructing the bridge scheme dataset of the bridge scheme and the influence factor data comprises: constructing a bridge scheme data table based on the bridge scheme and the influence factor data; constructing a key-value pair by taking the influence factor data and the bridge scheme as key value and value respectively; storing the key-value pair in the bridge scheme data table; taking the bridge scheme data table as the bridge scheme dataset comprising the bridge scheme and the influence factor data.

[0102] It should be noted that the bridge scheme and the influence factor data are constructed into a bridge scheme data table, and the generated different bridge schemes and the corresponding influence factor data are taken as value and key respectively, thereby constructing a key-value pair in the form of <Key, Value>, and the key-value pair is filled into the bridge scheme data table, the key-value pair is stored, and the bridge scheme data table is taken as the bridge scheme dataset comprising the bridge scheme and the influence factor data, forming a standardized bridge scheme dataset. In subsequent new bridge scheme design, the bridge scheme dataset in the bridge scheme database can be directly queried to obtain the corresponding bridge scheme and the influence factor data affecting the bridge scheme.

[0103] Optionally, after constructing the bridge scheme dataset, the bridge scheme dataset can be trained according to the artificial intelligence neural network, thereby generating a corresponding model. In subsequent new bridge scheme design, the corresponding bridge scheme is directly output according to the generated model, thereby improving the efficiency of bridge design.

[0104] After the construction of the bridge scheme dataset is completed, it further comprises: obtaining an initial deep neural network model; determining a target function according to the initial deep neural network model; performing model training on the bridge scheme dataset as a training sample set of the initial deep neural network model based on the target function, to obtain a target deep neural network model; migrating and deploying the target deep neural network model to a server to form a bridge intelligent decision algorithm service, and accessing a bridge design module of a GIS system in an interface manner; designing a bridge scheme of a new project by using the bridge scheme design module based on the target deep neural network model.

[0105] The initial deep neural network model is a self-built deep neural network model, which can be one or more of a convolutional neural network model (CNN), a recurrent neural network model (RNN), a deep belief network model (DBN), a deep auto-encoder model (AutoEncoder), and a generative adversarial network model (GAN).

[0106] It should be noted that the target function can be determined according to the initial deep neural network model, so that the bridge scheme data set is trained as the initial deep neural network model based on the target function, and the target deep neural network model is generated. The training data set includes a training set, a test set and a validation set. When there is a new bridge scheme of a project, the bridge scheme of the new project is directly designed by the target deep neural network model. The generated target deep neural network model can be migrated and deployed to a server to form a bridge intelligent decision algorithm service, and the bridge design module of the GIS system is accessed in an interface manner, so that the bridge scheme design module is used to design the bridge scheme of the new project based on the target neural deep network model.

[0107] In the bridge design, the GIS environment data and the interface data provided by the related upstream and downstream professionals are obtained through the GIS system; the control element information and the ground line information are obtained based on the GIS environment data and the interface data; the bridge scheme design is performed through the preset bridge automatic decision algorithm based on the control element information and the ground line information, and the bridge scheme is generated; the influence factors affecting the bridge scheme are analyzed based on the bridge scheme, and the influence factor data is collected; the bridge scheme data set of the bridge scheme and the influence factor data is constructed, the bridge scheme data set is stored in the bridge scheme database, the construction of the bridge scheme data set is completed, the standardized data sample set for the industry is constructed, the training sample data for the deep learning model of the bridge scheme intelligent design is provided, and then the accuracy and efficiency of the bridge design are improved through the intelligent design.

[0108] Reference Figure 3 , Figure 3 The flowchart of the second embodiment of the bridge scheme data set rapid construction method based on the GIS system of the present application is shown.

[0109] Based on the first embodiment, the step S20 of the bridge scheme data set rapid construction method based on the GIS system includes the following steps.

[0110] Step S201: determining the business rules based on the GIS environment data and the interface data.

[0111] It should be noted that when the GIS environment data and the interface data are obtained, the interface data includes the professional interface data of the line, geology and other upstream and downstream, so that the specific business rules can be determined based on the GIS environment data and the interface data.

[0112] Step S202: developing comprehensive route selection design according to the business rules, determining the line scheme, and performing engineering type section flagging to determine the boundary mileage of the roadbed engineering, bridge engineering and tunnel engineering.

[0113] In a specific implementation, after the business rule is determined, comprehensive route selection design can be carried out according to the business rule, so as to determine a specific route scheme and perform engineering type section flagging to determine the demarcation mileage of roadbed engineering, bridge engineering and tunnel engineering.

[0114] Step S203: determining a bridge section range according to the demarcation mileage.

[0115] Step S204: acquiring control element information and ground line information in the bridge section range.

[0116] It should be understood that after the demarcation mileage is determined, the bridge section range can be determined according to the demarcation mileage, so as to acquire relevant data such as control element information and ground line information in the corresponding bridge section range, thereby preparing to carry out a bridge automatic decision algorithm based on a traditional business rule.

[0117] In this embodiment, the GIS environment data and the interface data are used to determine the business rule, comprehensive route selection design is carried out according to the business rule, a route scheme is determined, engineering type section flagging is performed to determine the demarcation mileage of roadbed engineering, bridge engineering and tunnel engineering, the bridge section range is determined according to the demarcation mileage, and control element information and ground line information are acquired in the bridge section range, so that the specific route scheme can be quickly determined by acquiring the GIS environment data and the interface data, the control element information and the ground line information are obtained according to the specific route scheme, subsequent design of the bridge scheme is facilitated, and the efficiency of the bridge scheme design is improved.

[0118] Reference Figure 4 , Figure 4 FIG. 3 is a flowchart of a GIS system-based bridge scheme data set quick construction method according to a third embodiment of the present application.

[0119] Based on the first embodiment, the step S30 of the GIS system-based bridge scheme data set quick construction method according to the third embodiment specifically includes the following steps.

[0120] Step S301: determining an influence range of a bridge-under control point based on the control element information and the ground line information.

[0121] It should be noted that the bridge automatic decision algorithm based on the traditional business rule mainly calls a corresponding span bridge scheme to make a decision according to the influence range of the bridge-under control point, so the influence range of the bridge-under control point can be determined according to the control element information and the ground line information.

[0122] Step S302: calling multiple bridge schemes satisfying a constraint condition according to the influence range of the bridge-under control point, and performing evaluation by using a bridge scheme scoring rule algorithm to determine a scoring order of each bridge scheme.

[0123] It should be understood that after the influence range of the control point under the bridge is determined, the bridge scheme of the corresponding span can be called according to the influence range of the control point under the bridge to make a decision, for example, there is a scheme database for storing bridge schemes, and the bridge scheme of the corresponding span is queried in the scheme database through the influence range of the control point under the bridge. Since there can be multiple bridge schemes, multiple bridge schemes that meet the constraint conditions can be called to determine the final bridge scheme. The scores of each bridge scheme are determined through a bridge scheme scoring rule algorithm, thereby determining the initial bridge scheme. The bridge scheme scoring rule algorithm can be selected according to user needs, and each bridge scheme is scored through the bridge scheme scoring rule algorithm, thereby obtaining the score of each bridge scheme.

[0124] In a specific implementation, the bridge scheme mainly consists of three parts of a main girder scheme, a pier scheme and a foundation scheme, and then calling the bridge scheme of the corresponding span according to the influence range of the control point under the bridge to make a decision can be realized by the following steps: calling the main girder information, pier information and foundation information of the corresponding span according to the influence range of the control point under the bridge; obtaining the main girder scheme, pier scheme and foundation scheme respectively according to the main girder information, pier information and foundation information; and taking the main girder scheme, pier scheme and foundation scheme as the multiple bridge schemes that meet the constraint conditions.

[0125] In a specific implementation, the main girder information, pier information and foundation information of the corresponding span can be called through the influence range of the control point under the bridge, so that the specific main girder scheme, pier scheme and foundation scheme can be determined according to the main girder information, pier information and foundation information.

[0126] As shown in Figure 5 , the main girder information, pier information and foundation information of the corresponding span are called through the influence range of the control point under the bridge, and the specific main girder scheme, pier scheme and foundation scheme are determined according to the main girder information, pier information and foundation information. Figure 5The main girder scheme effect diagram is shown. The main girder scheme is composed of commonly used girder types, including the main girder name, structural system, span composition, main span span, support point beam height, mid-span beam height, main girder width, speed level and other attributes. According to the above attribute information, the LOD200 and above three-dimensional model profile of the structure can be drawn. The beam height information and beam width information in it are list data, which are composed of the beam height and beam width of each support point according to the span composition of the main girder. Commonly used main girder types include simply supported box girder, simply supported T girder, simply supported steel truss girder, simply supported tied arch, continuous beam, continuous rigid frame, continuous beam arch, continuous rigid frame arch and low tower cable-stayed bridge, etc. The structural system is divided into simply supported beam, continuous beam, composite beam, cable-stayed bridge, arch bridge and suspension bridge, etc. The cross-section characteristics are divided into equal height and width cross-section, equal height and variable width cross-section, variable height and width cross-section, variable height and span cross-section. The construction method of the main girder scheme is divided into prefabricated erection, support cast-in-place, cantilever cast-in-place, cantilever assembly, horizontal rotation, vertical rotation, incremental launching construction, etc. The span composition refers to the "side span span + secondary side span span + … + mid-span span + secondary side span span + side span span" of the main girder. The main girder cross-section is box cross-section, T cross-section, π cross-section and dumbbell cross-section, etc.

[0127] As shown in Table 1, Table 1 is a main girder scheme information table, which specifically includes the main girder name, structural system, span composition, main girder span, cross-section characteristics, beam height information, beam width information and construction method.

[0130] In this embodiment, the pier scheme is composed of the pier name, structural system, cross-section characteristics, pier height, whether hollow, applicable girder type and pier position. The pier height = line elevation - ground elevation - support point beam height. The pier scheme is determined comprehensively according to the main girder scheme and pier height and other factors. Generally, when the pier height is relatively low, a solid equal cross-section pier can be selected. When the pier height is medium, a solid variable cross-section pier can be selected. When the pier height is relatively high, a hollow variable cross-section pier can be selected. The variable cross-section pier mainly increases the cross-sectional size of the section close to the ground to improve the stiffness of the pier. The pier structural system includes single-column pier, double-column portal pier, multi-column portal pier, double-column H-shaped pier, A-shaped pier, etc. The pier cross-section includes circular cross-section, rectangular cross-section and round-end cross-section, etc. As shown in Table 2, Table 2 is a pier scheme information table. The pier scheme information includes the pier name, structural system, cross-section characteristics, pier height, whether hollow, applicable girder type and pier position.

[0131] Table 2

[0132]

[0133] In the basic scheme, the basic types are divided into pile foundation, open excavation foundation and well foundation, etc. The open excavation foundation is mostly multi-layer step rectangular expanded bottom shape, which is suitable for foundation buried depth within 6m; the well foundation is mostly equal cross-section rectangular hollow section, which is suitable for buried depth range of 4m-9m. The pile foundation is mainly group pile foundation, and its naming method conforms to the design habit of railway engineering. For example, 8-1.0m and 10-1.25m represent 8φ1m pile foundation and 10φ1.25m group pile foundation respectively. The commonly used pile diameters of railway are 1.0m, 1.25m, 1.5m, 2.0m, 2.5m, 3.0m, etc., the commonly used group pile numbers are 8, 9, 10, 11, 12, 16, etc., and the commonly used group pile arrangement modes are row-column type, plum blossom type and self-defined type, etc. The group pile foundation is combined and arranged by pile diameter, arrangement type and pile number to form different types of pile foundation configuration types. For example, Figures 6-7 as shown in Figure 6 , which is a schematic diagram of row-column type pile foundation arrangement, Figure 7 , which is a schematic diagram of plum blossom type pile foundation arrangement. For example Figures 8a-8d as shown in Figures 8a-8d , which is a schematic diagram of commonly used pile foundation scheme, Figure 8a , which is a schematic diagram of 9-1.0m pile foundation scheme, Figure 8b , which is a schematic diagram of 10-1.0m pile foundation scheme, Figure 8c , which is a schematic diagram of 11-1.0m pile foundation scheme, Figure 8d , which is a schematic diagram of 12-1.0m pile foundation scheme.

[0134] As shown in Table 3, Table 3 is a bridge group pile foundation parameter table, taking double-line high-speed railway bridge group pile foundation as an example, the group pile types include 8-1.0m and 9-1.25m, and other types can also be included, the pile cap parameters include length, width and height, the pile foundation parameters include number, diameter and default length, the 8-1.0m type is friction pile, and the arrangement form is row-column type, and the 9-1.25m type is column pile, and the arrangement form is plum blossom type.

[0137] Step S303: ranking the scores as the bridge scheme corresponding to the preset ranking as an initial bridge scheme, wherein the bridge scheme with the highest score is the initial bridge scheme.

[0138] It should be understood that the preset ranking is the bridge scheme with the largest ranking, i.e. the highest score, and the bridge scheme with the highest score in the score order is taken as the initial bridge scheme. The initial bridge scheme refers to the bridge scheme without rendering, and after obtaining the initial bridge scheme, the initial bridge scheme still needs to be rendered, so as to obtain the final bridge scheme.

[0139] Step S304: Render the initial bridge design based on the GIS system to generate a bridge design.

[0140] In practical implementation, the initial bridge design can be rendered using the GIS environment module in the GIS system, thereby generating the bridge design, such as... Figure 9 As shown, Figure 9 This is a schematic diagram of the initial bridge design rendering. The bridge design is generated by rendering the initial bridge design.

[0141] This embodiment determines the influence range of control points under the bridge based on the control element information and the ground line information; it calls up multiple bridge schemes that meet the constraints according to the influence range of the control points under the bridge, and evaluates them using a bridge scheme scoring algorithm to determine the score ranking of each bridge scheme; the bridge scheme corresponding to the preset ranking is used as the initial bridge scheme, wherein the bridge scheme with the highest score is the initial bridge scheme; the initial bridge scheme is rendered based on the GIS system to generate a bridge scheme, and the weight of each bridge scheme is determined by the control element information and the ground line information, thereby generating the initial bridge scheme, improving the accuracy of bridge design, and the rendering of the initial bridge scheme improves the effect of bridge design.

[0142] refer to Figure 10 , Figure 10 This is a flowchart illustrating the fourth embodiment of the method for rapidly constructing a bridge scheme dataset based on a GIS system according to the present invention.

[0143] Based on the first embodiment described above, step S40 of the rapid construction method for bridge scheme datasets based on a GIS system in this embodiment specifically includes:

[0144] Step S401: Analyze the bridge design to determine the geological elements that need to be avoided.

[0145] It should be noted that in special circumstances, it may be necessary to adjust the bridge design to avoid unfavorable geological elements. Specific adjustment measures may include increasing or decreasing the span, or changing the type of foundation, etc. Therefore, when it is necessary to determine the data on the influencing factors of the bridge design, the bridge design can be analyzed to determine the geological elements that need to be avoided when designing the bridge.

[0146] Step S402: Analyze the geological elements that need to be avoided to obtain information on the geological elements that affect the bridge design.

[0147] In practice, once the geological elements that need to be avoided are obtained, they can be analyzed to obtain information on the geological elements that affect the bridge design.

[0148] Step S403: determining the control elevation information based on the control element and the pier scheme in the bridge scheme.

[0149] It should be understood that the difference of the control elevation information jointly determines the pier scheme in the bridge scheme, and therefore the control elevation information can be determined based on the control element and the pier scheme in the bridge scheme.

[0150] Step S404: analyzing the control elevation information to obtain the line element information and the terrain element information affecting the pier scheme.

[0151] In the embodiment, the bridge scheme influencing factors include the line element information, the terrain element information, the control element information and the geological element information, the difference of the control elevation information of the line element information and the terrain element information jointly determines the pier scheme in the bridge scheme, and therefore the control elevation information can be analyzed to obtain the line element information and the terrain element information affecting the pier scheme.

[0152] Optionally, when the difference of the control elevation of the line element information and the control elevation in the terrain element information is small, the girder scheme is also affected, and generally a low-height girder scheme with a lower girder height needs to be selected.

[0153] Step S405: determining the girder main span size information based on the girder scheme of the bridge scheme.

[0154] It should be understood that the control element information mainly determines the girder main span size and further determines the girder scheme, and therefore the girder main span size information can be determined based on the girder scheme of the bridge scheme.

[0155] Step S406: analyzing the girder main span size information to obtain the control element information affecting the girder scheme.

[0156] After the girder main span size information is obtained, the girder main span size information can be analyzed to obtain the control element information affecting the girder scheme.

[0157] In specific implementation, the control element information is mainly the obstacles that the bridge needs to cross, and the common ground road, river, railway, pipeline and other structures are uniformly abstracted to form a control point model to obtain the control element name, control element type, control element level, control element mileage, control element intersection angle, influence line width, control element positive width, starting point mileage, end point mileage, limit width, limit height and ground elevation.

[0158] As shown in Table 4, Table 4 is a control element information table, and the control element information is mainly provided by the vector data of the road, river, railway, pipeline and other structure database of the GIS system.

[0159] Table 4

[0160]

[0161] Step S407: The geological element information, the terrain element information, the control element information, and the line element information provided based on the professional interface data are taken as influencing factors of the bridge scheme.

[0162] It should be noted that after obtaining the geological element information, the line element information provided based on the professional interface data, the terrain element information, and the control element information, the geological element information, the line element information provided based on the professional interface data, the terrain element information, and the control element information are taken as influencing factors of the bridge scheme.

[0163] Step S408: The geological element information, the terrain element information, the control element information, and the line element information provided based on the professional interface data are collected based on the GIS system to obtain influencing factor data.

[0164] It should be noted that the geological element information, the line element information provided based on the professional interface data, the terrain element information, and the control element information can be collected based on the GIS system to obtain the influencing factor data.

[0165] In specific implementation, since the vector database is stored in the GIS system, the vector data representing the control elements are stored in the vector database, but due to the influence of the collection precision of geographical geological data or the use of historical data, the vector data in the vector database is missing or incomplete, so it is necessary to construct the control elements. Optionally, the step of collecting the control element information based on the GIS system specifically includes: querying the original vector database in the GIS system through the bridge design scheme; when the corresponding vector data does not exist in the original vector database, taking the missing vector data as target control element data; constructing the target control element data to obtain a control element structure table; collecting the control element information based on the control element structure table.

[0166] The control element data in the bridge scheme region can be obtained through the bridge scheme, and the original vector database is queried through the control element data, so as to determine whether all the control element data can be queried in the original vector database. If the corresponding vector data does not exist in the original vector database, the missing vector data is taken as target control element data, so as to construct the target control element. The target control element data refers to the bridge understructure that needs to be crossed by the bridge structure when the bridge is designed, but the data is missing in the original vector database, including the control element data of river, road, railway, pipeline, house, and other ground structure.

[0167] For the control elements of river type, including non-navigable rivers and navigable rivers, non-navigable rivers are not classified, and navigable rivers are classified into first-class channels, second-class channels, etc. According to different classifications, different limit heights and limit widths are corresponded, and the specific parameters can be queried from the relevant technical standard documents. The technical standard documents can be “Inland Waterway Navigation Standard”, “Sea and River Navigation Standard”, etc.

[0168] For the control elements of road type, the grades are mainly divided into expressways, provincial roads, national roads, and rural roads, etc. According to different classifications and specific conditions, different limit heights and limit widths are corresponded. According to whether the road is planned, only the corresponding column attribute needs to be added.

[0169] For the control elements of railway type, the grades are mainly divided into high-speed railways, intercity railways, passenger and freight railways, heavy-load railways, special lines, and urban railways, etc. According to different classifications, different limit heights and limit widths are corresponded. The specific parameters can be consulted from technical standard documents such as “High-Speed Railway Design Specification”. For the control elements of pipeline type, the pipeline type is the general term of pipeline type and line type. The grade of pipeline is mainly divided according to the pressure grade of liquid or gas in the pipeline, which can be divided according to the self-defined division method. The line type is mainly electric wire, and the specific grade can be divided according to the voltage.

[0170] The function module of control element construction is developed in the GIS system. The target control element data can be abstracted by the function module of control element construction to obtain the abstracted control element, i.e. the target control element abstract data. The steps of obtaining the target control element abstract data specifically include abstracting the target control element data by the GIS system to obtain the control element name, control element type, control element grade, control element mileage, control element intersection angle, influence line width, control element normal width, starting point mileage, end point mileage, limit width, limit height, and ground elevation; the control element name, the control element type, the control element grade, the control element mileage, the control element intersection angle, the influence line width, the control element normal width, the starting point mileage, the end point mileage, the limit width, the limit height, and the ground elevation are taken as the target control element abstract data.

[0171] The target control element data can be abstracted by using the function module constructed by the control element, so that the control element name, control element type, control element level, control element mileage, control element intersection angle, influence line width, control element width, starting point mileage, end point mileage, limit width, limit height, and ground elevation can be abstracted as target control element abstract data. In specific implementation, the control element mileage is the center axis of the control element of the ground structure, the angle between the center axis and the line is the control element angle, the center axis of the control element is the reference line for positioning the control element, the mileage position and the intersection angle of the control element on the line are determined, the center axis of the control element can be set to a certain width, different representative patterns are selected according to different control element types, so that different effects can be rendered by texture mapping to distinguish the types, arrow symbols can be attached in the texture mapping to express direction information, such as the flow direction of a river, the traffic direction of a road, and the supply direction of a pipeline. The influence line width is mainly calculated through the geometric relationship between the control element width and the control element intersection angle, and the starting point mileage and the end point mileage are calculated by the control element mileage ± 0.5 times the influence line width.

[0172] When the target control element abstract data is obtained, the target control element abstract data can be rendered by using a GIS system, and the target control element abstract data can be intuitively rendered to obtain a target control element instance, which refers to the target control element after rendering. After obtaining the target control element instance, the obtained target control element instance information can be stored for subsequent data query. After the control element structure is completed, the target control element instance is stored, a control element structure table is generated, and control element information is collected based on the control element structure table.

[0173] When the target control element instance is obtained, a structured table corresponding to the control element can be generated and stored, and the structured table can be transmitted to a relational database such as Mysql for storage. In order to distinguish the currently generated control element instance data from the data in the original vector database, the currently generated data needs to be saved separately. As shown in Figure 11 , the control element structure table is generated and stored, and the control element information is collected based on the control element structure table. Figure 11 To construct the control element and the rendering schematic diagram, the vector data lacking in the vector database is constructed to improve the integrity of the data in the vector database.

[0174] The embodiment determines geological elements needing to be avoided by analyzing the bridge scheme, analyzes the geological elements needing to be avoided to obtain geological element information affecting the bridge scheme, determines elevation information based on a pier scheme in the bridge scheme, analyzes the elevation information to obtain line element information and topographic element information affecting the pier scheme, determines beam main span size information based on a main beam scheme of the bridge scheme, analyzes the beam main span size information to obtain control element information affecting the main beam scheme, takes the geological element information, the topographic element information, the control element information and line element information provided based on professional interface data as influence factors affecting the bridge scheme, collects the geological element information, the topographic element information, the control element information and the line element information provided based on the professional interface data based on a GIS system to obtain influence factor data, quickly obtains the influence factors affecting the bridge scheme by analyzing the bridge scheme, thereby quickly collecting the influence factor data and improving the efficiency of bridge scheme data set construction.
