[0045] To make the objectives, technical solutions, and advantages of the present disclosure more apparent, exemplary embodiments according to the present disclosure will be described in detail below with reference to the accompanying drawings. Apparently, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments of the present disclosure. It should be understood that the present disclosure is not limited by the exemplary embodiments described herein.

[0046] Embodiments of the present disclosure:

[0047] Referring to Figures 1 - 6 as shown, the present disclosure proposes a construction method for parametric modeling of a bridge construction trestle and generating a calculation report, which includes the following steps:

[0048] Step S1, automatic scheme generation: Automatic scheme generation mainly includes engineering requirement description, engineering element transformation, and engineering database construction, etc. Obtain the key engineering information, input the key engineering information into a pre-established large language model to obtain engineering elements, and obtain a preliminary design scheme applicable to the engineering elements through machine learning; the key engineering information includes the construction location, scene environment, and usage requirements of the proposed project, etc. The construction location of the project needs to be specific to the county-level administrative region; the scene environment needs to clarify the water area or geographical type where the trestle is erected; the usage requirements need to clarify the trestle construction and passing equipment, component transportation requirements, and flood crossing requirements.

[0049] Step S1 further includes the following steps:

[0050] Step S11, obtain the key engineering information; the key engineering information can be obtained in the form of user input;

[0051] Step S12, transform the key engineering information into engineering elements of the construction industry, bridge span layout, working conditions information, and load information through a large language model; engineering element transformation is to transform the user input information into key information such as bridge span layout, load type and size required for scheme selection.

[0052] Step S13, establish an engineering database, and use machine learning to give a preliminary design scheme applicable to the engineering elements;

[0053] Step S2, parametric construction of the trestle structure: The parametric construction of the trestle structure needs to digitalize and parameterize the engineering elements, and encode various engineering elements, that is, disassemble and divide the engineering elements to construct geometric parameter subclass data and load subclass data, and complete the parametric construction of the trestle structure according to the subclass data; specifically, step S2 includes:

[0054] Step S21: Further break down engineering elements such as the structural form, load case combination, and analysis type calculated for the trestle structure into bridge spans, clearances, longitudinal slopes, curvatures, deck elevations, self-weights, wind loads, wave forces, vehicle loads, and construction loads; this step is also to digitalize the engineering elements. Specifically, classify bridge spans, clearances, longitudinal slopes, curvatures, and deck elevations as geometric parameter subclass data; classify self-weights, wind loads, wave forces, vehicle loads, and construction loads as load subclass data.

[0055] Step S22: Establish the interrelationships of parameters such as the dimensions, spacings, and elevations of each component of the trestle based on the combination methods and spatial position relationships of each component; this step is also to parameterize the engineering elements. Specifically, the components include columns, cross beams, Bailey beams, primary and secondary beams, transverse and longitudinal distribution beams, bridge decks, etc.

[0056] Step S23: Code and number the component types and cross-sections according to the interrelationships of the parameters; engineering data coding is to code and number information such as the trestle structure, loads, and results.

[0057] Step S3: Automatic modeling calculation and analysis: The automatic modeling calculation and analysis mainly include element supplement, verification, and confirmation, automatic model establishment and calculation, result analysis and preliminary judgment, etc., that is, establish a geometric model, divide grid units, conduct structural force analysis and structural material consumption statistics, and extract scheme information and calculation analysis and statistical results;

[0058] Specifically, Step S3 includes:

[0059] Step S31: Automatically check whether the engineering elements in the preliminary design scheme are complete, and let the user decide whether to adjust and supplement the elements according to the actual working conditions.

[0060] The element supplement, verification, and confirmation are to automatically extract the engineering element data of the preliminary scheme design and display it on the user interface. If key information for calculation is missing, a prompt will be given for the user to supplement and verify. Engineering elements are the key information required for preliminary design discriminated and extracted by the large language model from the engineering information input by the user, mainly including industry categories (such as railway bridges, highway bridges, for selecting applicable specification standard documents for calculation), bridge span layout (given based on the layout principle of engineering cases combined with the trestle length input by the user), load case combination information (the load combinations specified by the code, the functions of the trestle input by the user such as beam transportation, concrete transportation, or local load information to give the load case combination of the trestle during normal use or flood discharge), load information (give data such as self-weight, vehicle load, wind load, water flow force, wave force, etc. based on load combinations, trestle bridge location address, cross-water area information, etc.). Among them, because some information may be incomplete due to the imperfect engineering information input by the user, it is necessary for the user to verify and confirm whether to adjust and supplement in Step S31.

[0061] Step S32: After the engineering element check and confirmation, call the CAE software to automatically establish a geometric model and divide grid elements, and automatically select the calculation analysis types and working condition load combinations that meet the specification requirements according to the working condition information, and conduct structural stress analysis and structural material consumption statistics; the structural stress analysis includes overall structural buckling analysis, modal analysis, and internal force, deformation, and stability analysis of components, and the structural material consumption statistics is to calculate the weights of components of various types in the selected scheme of the calculation model.

[0062] Step S33: Extract the scheme information and the calculation analysis and statistics results, compare them with the requirements of industry specifications to judge whether the mandatory requirements of the specifications are met. If not, return to S31 for element adjustment; if so, enter Step S4. The result judgment conditions are mainly the requirements for the overall structural yield ratio, and the limit values of flexural strength, shear strength, deflection, and stability of components in the specifications. The extraction of the scheme information and the calculation analysis and statistics results mainly realizes the screenshot of the model and calculation results, the extraction of calculation result data, the interception of calculation working condition animations, the extraction of component classification statistics data, etc., so as to be embedded in the dynamic statements of the report template in the later stage.

[0063] Step S4: Scheme analysis and evaluation: Obtain evaluation indicators, and the user balances various evaluation indicators based on actual needs; specifically,

[0064] Step S4 includes:

[0065] Step S41: Give evaluation indicators such as structural safety and reliability evaluation, scheme cost evaluation, and construction period progress evaluation according to the calculation results; the structural safety and reliability evaluation indicators can be expressed by, where β is the average value of the evaluation indicators β calculated separately for each type of component, is the evaluation indicator of components of different material types or grades (β﹤1), σ is the stress or deflection value of the component calculated by the model, [σ] is the specification design limit value of the component stress or deflection, and n is the number of single-type components in the structure; the scheme cost evaluation indicator is directly characterized by the economic cost price C (yuan), where m represents the engineering quantity of the i-th material extracted as described above, s represents the measurement unit price of the i-th material; the construction period progress evaluation is characterized by the construction period T (days) of the trestle structure, where m represents the engineering quantity of the i-th material extracted as described above, d represents the engineering quantity per single working day of the i-th material, and n is the number of working faces for simultaneous construction of this type of component; expressed as, where β is the average value of the evaluation indicators β calculated separately for each type of component, 1,2,3... and, is the evaluation indicator of components of different material types or grades (β 1,2,3... ﹤1), σ i is the stress or deflection value of the component calculated by the model, [σ i is the specification design limit value of the component stress or deflection, and n is the number of single-type components in the structure; the scheme cost evaluation indicator is directly characterized by the economic cost price C (yuan), where m i represents the engineering quantity of the i-th material extracted as described above, s i represents the measurement unit price of the i-th material; the construction period progress evaluation is characterized by the construction period T (days) of the trestle structure,

[0066] where m i represents the engineering quantity of the i-th material extracted as described above, d i represents the engineering quantity per single working day of the i-th material, and n is the number of working faces for simultaneous construction of this type of component;

[0067] Step S42: The user balances various evaluation indicators based on actual needs. If adjustment of indicators is required, the program automatically gives the recommended values of the adjustment items and returns to step S31 for parameter correction. If the evaluation indicators are not adjusted, proceed to the next step, step S5.

[0068] The prerequisite for balancing various evaluation indicators is the safety and reliability index, while the economic index and the construction period index are secondary indicators. The recommended values of the adjustment items include span, deck elevation, component material type, component layout spacing, etc.

[0069] Step S5: Definition and output of the standard calculation report: Generate and output a report file. The definition of the standard report mainly includes a predefined default standard report template and a custom standard report template. The output of the calculation report is to output information such as the scheme design, environmental scenario, load condition, structural component force analysis, and evaluation index analysis as a Word file according to the default or custom report template settings. Specifically, in implementation, step S5 includes:

[0070] Step S51: Define the chapter format and standard text statements of the standard analysis report word template, encode and define dynamic data such as design data, structural analysis data, and cost analysis data, and set corresponding embedding interfaces in the dynamic data statements; the dynamic data statements need to reserve interfaces to embed the corresponding encoded information in step S23, where the form of the analysis result information is not limited to text, charts, GIF animations, etc. Both the standard text statements and the dynamic data statements support user rewriting to facilitate the characterization of the calculation report.

[0071] Step S52: The user selects to use the default analysis report template or a custom template, and automatically grabs each dynamic data information and embeds it into the analysis report template;

[0072] Step S53: The user reprocesses the text content such as the engineering geology, hydrological information, and working condition information of the analysis report on the output interface in the interaction interface; that is, the interaction interface allows the user to review and reprocess the automatically output text information.

[0073] Step S54: Output the calculation report file. The calculation report is output as a Word file and can be selected to be saved in the local system of the computer.

[0074] Furthermore, in step S13, the engineering database includes an engineering instance database and an engineering specification database; the engineering instance data is the bridge span layout, component selection, working condition information, load information, etc. of the existing and under-construction engineering trestles; the engineering specification data is the material and load regulation information in the industry specifications of bridges, steel structures, wharves, hydrology, and building loads involved.

[0075] In the preliminary design plan in step S13, the bridge span setting of the proposed trestle project for the user will be given, including information such as the models and layout methods of components such as columns, cross beams, Bailey beams, primary and secondary distribution beams, etc.
