Description

Technical Field

[0001] This invention relates to the field of bridge engineering technology, and in particular to a method for estimating the quantity of bridge engineering projects based on a GIS system. Background Technology

[0002] With the development of digital and intelligent technologies, BIM (Building Information Modeling) and GIS (Geographic Information System) technologies are widely used in engineering construction. BIM models of bridge structures can display the structural dimensions in detail and calculate specific quantities. However, due to the large amount of information contained in BIM models and their high space consumption, loading and calculating large amounts of BIM models often results in screen display lag and a poor user experience.

[0003] GIS technology can be applied to large-scale engineering construction scenarios, especially in railway and highway engineering, where it can display detailed topography and existing buildings along the route. However, GIS technology has limited support for BIM models, and mainstream GIS systems lack full support for BIM. Currently, most new construction projects adopt a BIM+GIS approach, using GIS technology to create the engineering scene and BIM technology to create the engineering model. By simplifying and lightweighting the BIM model to generate a skin model, it is integrated with the GIS scene to achieve digital engineering, striking a balance between model accuracy and user experience.

[0004] Currently, during the operation of the BIM+GIS technology route, when BIM information is lost, if it is necessary to calculate the quantity of work but the corresponding attributes are missing, it is impossible to calculate the accurate quantity of work based on the precise attribute parameters, resulting in low accuracy of project cost calculation.

[0070] 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.

[0071] Reference Figure 1 , Figure 1 This is a schematic diagram of the structure of a bridge engineering quantity estimation device based on a GIS system, which is part of the hardware operating environment of the embodiment of the present invention.

[0072] like Figure 1 As shown, the bridge engineering quantity estimation device based on the GIS system 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 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.

[0073] Those skilled in the art will understand that Figure 1 The structure shown does not constitute a limitation on the bridge engineering quantity estimation equipment based on the GIS system, and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0074] like Figure 1 As 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 bridge engineering quantity estimation program based on a GIS system.

[0075] exist Figure 1 In the bridge engineering quantity estimation device based on the GIS system 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 bridge engineering quantity estimation device based on the GIS system of the present invention can be set in the bridge engineering quantity estimation device based on the GIS system. The bridge engineering quantity estimation device based on the GIS system calls the bridge engineering quantity estimation program based on the GIS system stored in the memory 1005 through the processor 1001 and executes the bridge engineering quantity estimation method based on the GIS system provided in the embodiment of the present invention.

[0076] This invention provides a method for estimating the quantity of bridge engineering projects based on a GIS system, referring to... Figure 2 , Figure 2This is a flowchart illustrating the first embodiment of the bridge engineering quantity estimation method based on a GIS system according to the present invention.

[0077] In this embodiment, the method for estimating the quantity of bridge engineering projects based on a GIS system includes the following steps:

[0078] Step S10: When calculating the cost of a bridge project, obtain the bridge structure information table from the GIS system.

[0079] It should be noted that this embodiment calculates the cost of bridge engineering using GIS, and the number of bridge projects can be calculated using a small number of model parameters within the GIS.

[0080] In practical implementation, when it is necessary to conduct bridge engineering cost estimation, a bridge engineering project route plan can be established in the GIS system, thereby generating a bridge structure information table for the work sites in this bridge engineering cost estimation. The bridge structure information table refers to the bridge structure information of the number of bridge works in this bridge engineering cost estimation project. The bridge structure information may include beam structure, pier structure, foundation structure, construction auxiliary measures structure, etc., which are not limited in this embodiment.

[0081] In practice, the bridge structure information table at the construction site includes the bridge name, bridge center mileage, bridge starting mileage, bridge ending mileage, a list of bridge pier heights, and a list of bridge beam types.

[0082] Step S20: Determine the structural type of the bridge at the work site based on the bridge structure information table.

[0083] It should be understood that once the bridge structure information table at the work site is obtained, the bridge structure information in the bridge project can be obtained, thereby determining the structural type of the bridge project at the work site. The structural types of the bridge project at the work site include: beam structure type, pier structure type, foundation structure type, and construction auxiliary measures structure type, etc.

[0084] Step S30: Determine the corresponding structural dimension parameters based on the structural type of the bridge project at the construction site.

[0085] In practice, different bridge engineering structures at different work sites have corresponding structural dimensional parameters, which allows for the calculation of the quantity of bridge engineering structures based on these parameters. For example, the structural dimensional parameters of the beam engineering structures can be obtained based on the beam engineering structure type, and the quantity of beam engineering structures can be calculated accordingly.

[0086] Step S40: Calculate the number of structures corresponding to the structural type of the bridge project at the work site based on the structural type and the structural dimension parameters, and generate a structural quantity data table.

[0087] It is understandable that the structural dimensions of bridge projects at the construction site vary depending on their structural type. For structural types with complete structural dimensions, the corresponding number of structures can be calculated based on these dimensions. For structures in the model where the number of corresponding points cannot be calculated due to missing structural dimensions, empirical parameters can be configured based on similar engineering experience to calculate the number of structures lacking structural dimensions. For structural types with simplified models and missing structural components, configuration information needs to be provided based on other relevant parameters and experience, and further calculations are required to calculate the corresponding number of structures. The calculated number of structures is then summarized to obtain a structural quantity data table.

[0088] Step S50: Generate a summary table of the number of bridges at the construction site based on the structure quantity data table.

[0089] In practice, once the structural quantity data tables corresponding to the structural types of bridge projects at different work sites are obtained, all structural quantity data tables can be summarized to generate a summary table of bridge quantities at different work sites.

[0090] like Figure 3 As shown, Figure 3 This is a schematic diagram of the overall process for GIS-based bridge quantity estimation in this embodiment. When bridge quantity estimation is required, a specific project can be identified in the GIS system, and a new route plan can be created. A rule file is configured based on the route plan, and the designed bridge model is determined according to the rule file. An experience database and a basic type database are established for bridge structures whose quantities cannot be directly calculated from the bridge model. Based on the experience of professional technicians, the quantities of various bridge structure types are configured according to experience and summarized to establish the experience database. The basic type database refers to the database established for various types of bridge structure data. For example, if the bridge structure type at the work site is a pier, an experience database for the quantity of piers of various pier types can be established, and a basic type database can be generated for each pier type. A bridge plan is established by configuring the rule file, and a summary information table of the project's bridges is obtained. Based on the route plan of the bridge engineering project, the specific bridge structure information of each work site is determined, thus obtaining the bridge structure information table for each work site. After obtaining the bridge structure type of each work site, the corresponding quantity of each structure can be obtained according to the structural parameters and experience database, and the corresponding structural quantity table is generated, namely the beam quantity information table, the pier quantity information table, the foundation quantity information table, and the construction auxiliary measures quantity table. Thus, the quantity of each engineering structure can be queried, and the quantity of bridge engineering can be queried.

[0091] Step S60: Based on the summary table of bridge quantities at the work sites, query the bridge engineering structure quantity information coding table to determine the engineering structure quantity code.

[0092] In practice, the bridge engineering structure quantity information coding table includes the quantity of bridge engineering structures and their codes. There is a mapping relationship between the engineering structure quantity codes and the cost quota codes. Therefore, the corresponding engineering structure quantity codes can be queried in the bridge engineering structure quantity information coding table based on the quantity of each bridge engineering structure in the summary table of bridge quantities at the work site.

[0093] Step S70: Obtain the cost quota according to the quantity code of the engineering structure, and calculate the cost of the bridge project according to the cost quota.

[0094] In this embodiment, a mapping relationship table can be queried based on the quantity code of the engineering structure. The mapping relationship table contains the mapping relationship between the bridge engineering structure code and the cost quota code. The corresponding cost quota code is obtained based on the quantity code of the bridge engineering structure, and then the cost quota corresponding to the cost quota code is obtained. The cost of the bridge project is calculated based on the cost quota.

[0095] Further, the step of calculating the bridge project cost in step S70 specifically includes: obtaining the original bridge project structure quantity information and the original project cost quota information; encoding the original bridge project structure quantity information and the original project cost quota information respectively to obtain the original project structure quantity code and the original cost quota code; establishing a mapping relationship between the project structure quantity and the cost quota based on the original project structure quantity code and the original cost quota code to obtain a mapping relationship table; querying the mapping relationship table based on the project structure quantity code to obtain the corresponding cost quota, and calculating the bridge project cost based on the cost quota.

[0096] It should be noted that before calculating the cost of a bridge project, all structural quantity information of the bridge project can be coded, as can the cost quota information. The original structural quantity information of the bridge project refers to the quantity information of all bridge project structures, and the original cost quota information refers to the cost quota information. By coding the original structural information of the bridge project and the original cost quota information respectively, the original structural quantity code and the original cost quota code are obtained.

[0097] It should be understood that by setting up a mapping table between project quantities and cost quotas in GIS, a mapping relationship between project structure quantities and cost quotas can be established based on the original project structure quantity codes and cost quota codes, resulting in a mapping table. This mapping table can be established using a dictionary (key, value) format data structure. From the project structure quantity codes, cost quota codes can be obtained, and then cost quotas can be derived. The cost of bridge projects can then be calculated based on these cost quotas.

[0098] The cost quota can be selected based on the design depth of the bridge project, including relevant quota standards such as preliminary quotas and estimated quotas. This embodiment does not limit this. The cost quota is coded and matched with the code corresponding to the structural quantity. Thus, the quota code can be obtained by querying the structural quantity code, and then the corresponding cost quota can be queried based on the quota code. The structural quantity code can be coded according to the coding rules of the bridge project, encoding each structure that generates the quantity of work. The characteristics and location of the structure can be parsed from the code. The structural quantity code of the bridge project can be encoded using a multi-way tree data structure, and the code can be extended to adapt to different levels of coding depth.

[0099] like Figure 4 As shown, Figure 4 This is an example diagram illustrating the bridge structure information coding in this embodiment. By confirming the bridge project, for example, if the bridge project is a double-track railway project, the overall project is coded as Double-track Railway Project 1. Based on the division of double-track railway projects, they are further divided into box girder bridge projects, T-beam bridge projects, frame bridge projects, and culvert bridge projects, respectively coded as Box Girder Bridge Project 1, T-beam Bridge Project 2, Frame Bridge Project 3, and Culvert Bridge Project 4. If other bridge projects exist, they can be coded sequentially. Each bridge project is further divided; for example, a box girder bridge project includes extra-large bridges, large bridges, medium bridges, and small bridges, which are coded sequentially as Extra-large Bridge 1, Large Bridge 2, Medium Bridge 3, and Small Bridge 4. Extra-large bridges include main works, ancillary works, demolition works, foundation construction auxiliary facilities, testing works, etc., and can be coded according to the importance of the project, with the main works coded as Main Works 1, ancillary works coded as Ancillary Works 2, etc. By coding each project, a bridge structure information coding table is generated.

[0100] This embodiment obtains the bridge structure information table from the GIS system when calculating bridge project costs; determines the bridge structure type based on the information table; determines the corresponding structural dimension parameters based on the structure type; calculates the corresponding structural quantity data table based on the structure type and dimension parameters; generates a summary table of bridge quantities based on the summary table; and queries the bridge structure quantity information coding table to determine the structural quantity code. This yields the cost quota for calculating bridge project costs. The GIS system can be directly used to classify bridge structures, enabling rapid and accurate calculation of quantities and improving the accuracy of cost calculations.

[0101] refer to Figure 5 , Figure 5 This is a flowchart illustrating the second embodiment of the bridge engineering quantity estimation method based on a GIS system according to the present invention.

[0102] Based on the first embodiment described above, step S40 of the bridge engineering quantity estimation method based on the GIS system in this embodiment specifically includes:

[0103] Step S401: Determine the route plan for the bridge engineering project.

[0104] It should be noted that when a bridge engineering cost engineer is required, a bridge engineering project route plan can be created in the GIS system, thereby determining the specific route plan for the bridge engineering project.

[0105] Step S402: Configure the rules for abutment, pier type, beam type, foundation type, and bridge-road boundary according to the route plan of the bridge project.

[0106] In practice, once the route plan for a bridge project is determined, GIS can be used to configure the rules for the route plan, thereby generating corresponding rule files. By using GIS to configure the rules for the abutments, piers, beams, foundations, and bridge-road boundaries of the route plan, rule files for abutment rules, pier rules, beam rules, foundation rules, and bridge-road boundaries can be generated.

[0107] Step S403: Determine the preset bridge engineering structure type according to the rule file, and establish an experience quantity database and a basic type database corresponding to the preset bridge engineering structure type.

[0108] Once the rule file is generated, the number of bridge engineering structures that cannot be directly calculated can be determined based on the rule file. The preset bridge engineering structure type refers to the structure whose quantity cannot be directly calculated based on the structural dimension parameters. Based on the experience of professional technicians, the quantity of various bridge structure types is configured according to experience, and an experience database is established by summarizing the data. A foundation type database is also generated for various pier types.

[0109] Step S404: When the structural dimension parameter is missing, query the corresponding experience quantity database according to the structural type of the bridge project at the work site to obtain the structural quantity data table corresponding to the structural type of the bridge project at the work site.

[0110] In practice, when the structural dimension parameters corresponding to the structural type of the bridge project at the work site are incomplete or nonexistent, the corresponding empirical quantity database can be queried according to the specific type of the bridge project structure at the work site to obtain the empirical dimension parameters. Based on the empirical dimension parameters, the structural quantity data corresponding to the structural type of the bridge project at the work site can be calculated and a structural quantity data table can be generated.

[0111] Furthermore, the step of querying the corresponding empirical quantity database based on the structural type of the bridge project at the work site to obtain the structural quantity data table for the structural type of the bridge project at the work site when the structural dimension parameter is missing includes: when the structural type of the bridge project at the work site is a pier structure, determining that the structural dimension parameter of the pier structure is missing; obtaining the pier type parameter and pier height parameter corresponding to the pier structure; querying the corresponding empirical quantity database of piers based on the pier type parameter and pier height parameter to generate the pier quantity data table for the bridge project at the work site.

[0112] It should be understood that when the bridge structure at the work site is a pier structure, because not all the parameters needed to calculate the number of piers can be obtained through GIS, the structural dimensions of the pier structure are incomplete. Therefore, the number of piers needs to be obtained from a pier experience database. This allows us to obtain the pier type and height parameters for each pier structure, and then determine the number of experienced pier structures based on these parameters. This results in a table showing the number of piers for the bridge at the work site. As shown in Table 1, this table contains the pier experience database. Different pier heights correspond to different concrete volumes and steel reinforcement weights; therefore, the number of pier structures can be queried based on the pier height parameter.

[0113] Table 1

[0114]

[0115]

[0116] like Figure 6 As shown, Figure 6 This is a flowchart for calculating the number of bridge piers. When calculating the structure of a bridge project, the corresponding construction site bridge can be selected, and the corresponding structural type can be determined. When the structural type is a pier structure, the pier height information can be obtained. Based on this pier height information, a reference drawing database can be queried. This database contains pier drawings of various types. When a corresponding pier height is found in the reference drawing database, the quantity of piers can be queried from the reference drawing quantity database. This database contains experienced pier quantity data established in advance based on experience. If a pier drawing with the corresponding pier height is not found in the reference drawing database, the pier reference drawing information can be entered into the reference drawing quantity database to query the specific number of piers and generate a pier quantity table, which is then written into the project database.

[0117] This embodiment determines the route plan for a bridge engineering project; configures rules for abutments, pier types, beam types, foundation types, and bridge-road boundary boundaries based on the route plan; determines the preset bridge engineering structure type based on the rule file, and establishes an experience quantity database and a foundation type database corresponding to the preset bridge engineering structure type; when structural dimension parameters are missing, the corresponding experience quantity database is queried based on the bridge engineering structure type at the work site to obtain a structural quantity data table corresponding to the bridge engineering structure type at the work site. Before calculating the bridge engineering cost, an experience database can be established for structures whose structural quantities cannot be directly calculated. When there are relevant structural types to calculate structural quantities, the corresponding experience database can be directly queried to obtain the corresponding structural quantities, resulting in accurate engineering quantities. Engineering quantities can be calculated in GIS with fewer model parameters, improving the efficiency of structural quantity calculation and thus improving the efficiency and accuracy of bridge engineering cost calculation.

[0118] refer to Figure 7 , Figure 7 This is a flowchart illustrating the third embodiment of the bridge engineering quantity estimation method based on a GIS system according to the present invention.

[0119] Based on the first and second embodiments described above, step S40 of the bridge engineering quantity estimation method based on the GIS system in this embodiment specifically includes:

[0120] Step S401': When the bridge engineering structure type at the construction site is a basic engineering structure, the structural dimension parameters of the basic engineering structure are determined to be no dimension parameters.

[0121] In practice, since the bridge structure model in GIS does not contain a foundation structure or the foundation structure is only schematic, the bridge structure model in the GIS system does not have the structural dimension parameters corresponding to the foundation engineering structure.

[0122] When the structural type of the bridge project at the construction site is a foundation project, the structural dimensions of the foundation project are not specified. When the foundation project has no dimensional parameters, the foundation configuration information needs to be configured based on engineering experience.

[0123] Step S402': Query the corresponding pier experience database to obtain the basic experience configuration parameters.

[0124] It should be understood that the structural quantity of the foundation project needs to be determined by the experience quantity of bridge piers to obtain the foundation experience configuration parameters. Therefore, the relevant beam parameters can be obtained by querying the pier experience quantity database based on the pier height corresponding to each bridge pier, and then further combined with the foundation type rule file to obtain the foundation experience configuration parameters.

[0125] Step S403': Determine the basic type parameters based on the engineering experience parameters and the basic experience configuration parameters.

[0126] It should be noted that engineering experience parameters refer to parameters set by bridge engineering technicians based on engineering experience. These parameters are used to query and supplement the basic experience configuration parameters, resulting in the foundation type parameters. The foundation type parameters can be obtained by querying the bridge foundation experience configuration table using the pier height parameters.

[0127] As shown in Table 2, Table 2 is an empirical configuration table for the foundation of a double-track high-speed railway bridge, taking a simply supported beam as an example.

[0128] In Table 2, the foundation type parameters are obtained by using the pier height parameter and the simply supported beam span. For example, if the pier height is 10m and the simply supported beam span is 24m, then the foundation type parameter is 8-1.0m.

[0129] Table 2

[0130]

[0131] Step S404': Query the basic type database based on the basic type parameters to obtain the empirical structure parameters.

[0132] In practice, the basic type database contains various basic type tables, allowing users to query the corresponding basic type tables based on different types of basic projects, thereby obtaining the calculable number of adopted experience structures.

[0133] Step S405': Calculate the number of structures corresponding to the structural type of the bridge project at the work site using the empirical structural parameters, and generate a data table of foundation engineering quantities.

[0134] This allows for the calculation of the number of structures corresponding to the structural types of bridge projects at the work site based on the empirical structural adoption number, and the generation of a data table of foundation engineering quantities.

[0135] Foundation engineering can include different types of foundations. For example, the foundations of high-speed railway double-track bridges generally consist of open-cut foundations, pile foundations, and well foundations.

[0136] like Figure 8 As shown, Figure 8This is a schematic diagram illustrating the calculation process for bridge foundation engineering quantities. When calculating the quantity of bridge structures, the corresponding work site bridge can be selected, and beam information, environmental geological information, and pier height information can be obtained. Based on the pier height and beam information, the foundation configuration experience database is queried. If a foundation configuration experience exists in the database, the pier foundation type can be obtained from the database, and the pier foundation depth can be obtained through the environmental geological information. Thus, the quantity of foundation engineering is calculated based on the pier foundation type and pier foundation depth, and a foundation engineering quantity data table is generated and written into the project database.

[0137] Furthermore, when the type of foundation engineering is a pile group foundation engineering, the steps for calculating the corresponding structural quantity include: when the structural type of the bridge engineering at the work site is a pile group foundation engineering structure, querying the pier experience quantity database to obtain the foundation experience configuration parameters of pier height, concrete volume, and steel reinforcement weight; determining the pile group foundation type parameters based on the engineering experience parameters and the pier height parameters; querying the corresponding pile group foundation type database based on the pile group foundation type parameters to obtain the experience structural dimension parameters of pile cap parameters, pile foundation parameters, and reinforcement ratio; calculating the pile group foundation engineering quantity using the pile cap parameters, the pile foundation parameters, and the reinforcement ratio, and generating a pile group foundation engineering quantity data table.

[0138] It should be understood that the pier experience quantity database includes a pier experience quantity data table. This table can be queried based on the pier height parameter. For example, if the pier height parameter is 6m, the resulting foundation experience configuration parameters would be: pier height 6m, concrete volume 120m³. 3 The weight of the reinforcing steel is 523kg. Based on engineering experience parameters, the span of the simply supported beam is obtained. For example, if the span of the simply supported beam is 32m and the pier height parameter is 6m, then the parameter for the pile foundation type obtained by querying is 8-1.0m.

[0139] In practice, once the pile foundation type parameters are obtained, the pile foundation type table in the pile foundation type database can be queried based on the pile foundation type parameters to obtain empirical structural dimension parameters such as pile cap parameters, pile foundation parameters, and corresponding reinforcement ratios. Based on these empirical structural dimension parameters, the quantity of pile foundation works can be calculated, and a pile foundation work quantity data table can be generated.

[0140] Depending on the diameter of the piles, pile groups are generally classified into types such as 8-D, 9-D, 10-D, 11-D, and 12-D, where D represents the diameter, typically 1.0m, 1.25m, 1.5m, 2.0m, 2.5m, and 3.0m. The length of the piles can be determined based on geological conditions or specified directly by the user in the system. Figure 9 As shown, Figure 9This is a schematic diagram of the bridge structure pile foundation in this embodiment, using 10-1.25m as an example for explanation.

[0141] As shown in Table 3, Table 3 is a table of bridge pile foundation types.

[0142] Table 3

[0143]

[0144] In Table 3, when the pile group foundation type parameter is 8-1.0m, the pile cap parameters are: pile cap length 5.4m, pile cap width 10.2m, pile cap height 2.0m. The pile foundation parameters are: number of piles 8m, pile diameter 1.0m, pile cap reinforcement ratio 5%, pile foundation reinforcement ratio 1%, type is friction pile, and the arrangement is row-column.

[0145] In this embodiment, the calculation process for the number of pile foundations is as follows: Equations 1-4:

[0146] The volume of concrete for the foundation cap = the length of the foundation cap × the width of the foundation cap × the height of the foundation cap (Equation 1)

[0147] Number of steel bars in the foundation cap = Volume of concrete in the foundation cap × Reinforcement ratio of the foundation cap (Equation 2)

[0148] Volume of pile foundation concrete = (Pile foundation volume) × 0.25 × πD 2 × Pile length (Formula 3)

[0149] Quantity of steel reinforcement in pile foundation = Volume of concrete in pile foundation × Reinforcement ratio of pile foundation (Equation 4)

[0150] The quantity of pile foundation projects can be calculated using equations 1-4 above, thereby generating a data table representing the quantity of pile foundation projects of different types.

[0151] This embodiment determines that the structural dimensions of the foundation structure are zero when the bridge structure at the construction site is a basic structure. It then queries the corresponding pier experience database to obtain the foundation experience configuration parameters. Based on the engineering experience parameters and the foundation experience configuration parameters, it determines the foundation type parameters. Next, it queries the foundation type database to obtain the experience structure parameters. Finally, it calculates the quantity of structures corresponding to the bridge structure type at the construction site using the experience structure parameters and generates a foundation quantity data table. This allows for quick querying of the corresponding foundation experience configuration parameters from the pier experience database and provides accurate foundation type parameters based on the engineering experience parameters and foundation experience configuration parameters obtained by technical personnel. This enables accurate calculation of the foundation quantity data, facilitating the calculation of bridge project costs.

[0152] refer to Figure 10 , Figure 10This is a flowchart illustrating the fourth embodiment of the bridge engineering quantity estimation method based on a GIS system according to the present invention.

[0153] Based on the first and second embodiments described above, step S40 of the bridge engineering quantity estimation method based on the GIS system in this embodiment specifically includes:

[0154] Step S401”: When the bridge structure type at the construction site is a beam structure, obtain the beam structure dimension parameters based on the beam structure.

[0155] It should be noted that all structural dimensional parameters required for calculating the quantity of beam structures can be directly obtained through the GIS system, thus allowing direct calculation of the quantity of beam works corresponding to the beam structures using these structural dimensional parameters.

[0156] In practice, when the bridge structure at the construction site is a beam structure, all structural dimension parameters required to calculate the number of beam structures can be directly obtained from the GIS system based on the beam structure, thus obtaining the beam structure dimension parameters.

[0157] Step S402”: Calculate the quantity of beam works based on the beam structure dimension parameters and generate a beam work quantity data table.

[0158] In practice, once the structural dimensions of the beams are obtained, the quantity of beam work can be directly calculated using the corresponding calculation function based on these dimensions, and a beam work quantity data table can be generated and written into the project database.

[0159] Step S403”: When the bridge structure type at the work site is a construction auxiliary measure structure, query the foundation type database to obtain empirical structural dimension parameters.

[0160] In this embodiment, when the bridge engineering structure type at the work site is a construction auxiliary measure structure, the construction auxiliary measure structure mainly includes cofferdams, foundation pit protection, underwater trestle bridges, underwater drilling platforms, and other construction auxiliary measure structures. The specific parameters of the relevant construction auxiliary measure structures can be calculated according to certain rules based on the basic configuration information, thereby calculating the specific quantity of construction auxiliary measures engineering based on the parameters.

[0161] Therefore, one can query the basic type database to obtain empirical structural dimension parameters, including specified pile length data, pile cap parameter data, etc.

[0162] Step S404: Obtain environmental information and auxiliary engineering configuration rule files for the bridge at the work site.

[0163] It should be understood that the environmental information table of the bridge at the work site can be queried to determine whether the bridge pier foundation is located in water, soft soil, or in an earthquake zone, etc., and auxiliary engineering configuration rule files can be obtained.

[0164] Step S405: Determine the construction auxiliary engineering experience parameters based on the environmental information and the auxiliary engineering configuration rule file.

[0165] In practice, based on environmental information and auxiliary engineering configuration rules, it is possible to calculate whether a trestle bridge or cofferdam is to be set up at the construction site, as well as the information on underwater drilling permits, and obtain the corresponding construction auxiliary engineering experience parameters.

[0166] Step S406”: Calculate the quantity of construction auxiliary measures based on the empirical parameters of the construction auxiliary engineering and the empirical structural dimension parameters, and generate a data table of the quantity of construction auxiliary measures.

[0167] It should be noted that once the empirical parameters of construction auxiliary engineering and empirical structural dimensions are obtained, the quantity of construction auxiliary measures can be calculated and a data table of construction auxiliary measures can be generated.

[0168] In practical implementation, taking the calculation of cofferdam quantities as an example, the calculation principle is as follows: Cofferdam length (width) = Abutment length (width) + Construction space, where the construction space is generally 0.5~1m; Cofferdam height = Underwater portion + Anchoring + Reserved portion, where the underwater portion is the water depth, and the reserved portion is generally 0.5m~1.0m; Cofferdam perimeter area - (Cofferdam length + Cofferdam width) × 2 × Cofferdam height. The unit weight per square meter of cofferdam steel is determined based on experience: 300kg per square meter for double-walled steel cofferdams and steel caisson cofferdams; 200kg per square meter for single-walled steel cofferdams; 200kg per square meter for interlocking steel pipe pile cofferdams; and 180kg per square meter for steel sheet pile cofferdams. Total cofferdam weight = Cofferdam perimeter area * Steel unit weight per square meter + Additional weight of cofferdam. The additional weight of the cofferdam is a custom weight, with a default value of zero. The cofferdam type selection is as follows: within water depth H1, select steel sheet pile cofferdam; within water depth H1 to H2, select single-wall steel cofferdam; within water depth H2 to H3, select double-wall steel cofferdam; above water depth H3, select caisson cofferdam; where H1 = 5.0m, H2 = 10m, and H3 = 15m.

[0169] like Figure 11 As shown, Figure 11This is a flowchart for calculating the quantity of construction auxiliary measures. Before calculating the quantity of construction auxiliary measures, auxiliary measures rules can be configured and corresponding piers can be selected. By querying the pier environmental information and pier height information, it can be determined whether the pier is in water. If the pier is in water, the water depth information can be obtained. If the water depth exceeds the set height h, a trestle bridge is set, and the number of trestle bridges is obtained. If the water depth does not exceed the set height h, a steel sheet pile cofferdam and a double-walled steel cofferdam are set, and the number of cofferdams is obtained. The foundation configuration is obtained by querying the pier height information. The foundation cap parameter information is obtained from the foundation configuration, and the cofferdam parameters are obtained from the foundation cap parameters and water depth information. It can also be determined whether it is a foundation pit protection based on the pier environmental information. If it is a foundation pit protection, the foundation pit depth and foundation pit protection parameters can be obtained from the foundation cap parameters, thus obtaining the number of foundation pit protection measures. If no foundation pit protection is set, the number of cofferdams and foundation protection measures are obtained from the rule database, thus obtaining the quantity of construction auxiliary measures, generating a construction auxiliary measures quantity data table, and writing it into the project database.

[0170] In this embodiment, when the bridge structure at the work site is a beam structure, the dimensional parameters of the beam structure are obtained based on the beam structure; the quantity of beam works is calculated based on the dimensional parameters of the beam structure, and a beam work quantity data table is generated; when the bridge structure at the work site is a construction auxiliary measure structure, the foundation type database is queried to obtain empirical structural dimensional parameters; the environmental information and auxiliary engineering configuration rule file of the bridge at the work site are obtained; empirical parameters for construction auxiliary engineering are determined based on the environmental information and the auxiliary engineering configuration rule file; the quantity of construction auxiliary measures works is calculated based on the empirical parameters of construction auxiliary engineering and the empirical structural dimensional parameters, and a construction auxiliary measure work quantity data table is generated. Different structural dimensional parameters can be calculated according to the different types of bridge structures at the work site. When the bridge structure at the work site is a construction auxiliary measure structure, the quantity of construction auxiliary measures works can be quickly calculated based on the pier environmental information and pier parameter information, improving the efficiency and accuracy of bridge project cost calculation.
