[0002] Underground power tunnels are enclosed underground passages designed specifically for the safe laying of urban high-voltage cables. As core infrastructure for modern urban power grid upgrades, their intensive layout addresses the dual challenges of land resource constraints and power transmission safety. These tunnels typically consist of reinforced concrete or prefabricated segments, with cable supports installed inside to support multiple high-voltage cables. They are also equipped with working shafts, ventilation systems, drainage pumping stations, and fire isolation facilities to ensure a stable operating environment for the cables. The large-scale application of underground power tunnels not only improves power supply reliability but also provides support for new energy access and smart city development. In the future, they will continue to evolve towards in-depth, standardized, and lifecycle digitalization.

[0033] The following is combined with Figure 1 - Attachment Figure 5 The specific implementation of the embodiment of the present invention is described in detail. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the present invention, and is not used to limit the embodiment of the present invention.

[0034] It should be noted that the acquisition, transmission, storage, use, and processing of data in the technical solution of this application are in compliance with the relevant provisions of national laws and regulations. In the embodiments of this application, certain software, components, models, and other existing solutions in the industry may be mentioned. These should be considered as exemplary. Their purpose is only to illustrate the feasibility of implementing the technical solution of this application, but it does not mean that the applicant has or will necessarily use such solutions.

[0035] Example 1

[0036] Reference Figure 1 - Figure 5 , which is the first embodiment of the present invention, provides a parametric design method and system for an underground power tunnel, including:

[0037] S100: receiving input underground power tunnel design related parameters through a parameterized algorithm, and performing multi-constraint verification and parameter correlation check.

[0038] It should be noted that the parameterized algorithm calls the H3D graphics engine rather than directly operating the underlying graphics data.

[0039] The H3D graphics engine is a three-dimensional graphics platform for solid features. It can calculate the parameters and set parameters through the mathematical relationship between the parameters of conventional solid models and the set parameters, drive model updates, and realize the parameterization of conventional solid models. It can sketch unconventional entities, determine the feature entities and corresponding parameters based on the modeling method of defining sketches, determine the mathematical relationship between the parameters and set parameters, calculate the parameters and set parameters, drive model updates, and realize the parameterization of unconventional solid models. This graphics engine realizes the diversified generation and real-time display of parametric models by building a basic graphics library and a visual model interface.

[0040] Specifically, the application scenarios and functional requirements are determined based on the design objectives; parametric algorithms are implemented through engine functions such as dimensional constraints, feature bodies, Boolean operations, and geometric constraint solving. Geometric constraints here refer to the mathematical functional relationships between relevant design parameters of underground power tunnels.

[0041] Furthermore, the input underground power tunnel design-related parameters are identified and divided into fixed parameters and variable parameters; a mathematical function relationship between the variable parameters and the fixed parameters is defined, and dynamically updated geometric constraint rules are generated.

[0042] Furthermore, users input parameters related to the underground power tunnel design through the interface, such as geometric dimensions (such as shaft wall thickness, shaft length / width / height, and pipe diameter), material properties (such as concrete type, steel grade, and protective layer thickness), structural parameters (such as the number of bins and layers), embedded part types (such as well holes, pipe holes, and sump pits), and load parameters (soil pressure, groundwater pressure).

[0043] Furthermore, dependencies are defined, such as the wellbore wall thickness automatically adjusting with the inner and outer diameters.

[0044] Furthermore, the legality of the input underground power tunnel design-related parameters is checked, including negative value interception, such as a pop-up window prompting "well wall thickness cannot be negative"; geometric conflict detection, such as a pop-up window prompting "parameter conflict" when the wellbore diameter exceeds the well wall range.

[0045] Furthermore, mechanical verification was carried out using the finite element method to calculate the crack width (≤0.2mm, representing that the calculated result of the verification concrete crack width should not exceed 0.2mm (GB50010-2010 Concrete Structure Design Standard) and anti-floating stability (anti-floating stability coefficient ≥1.15, representing that the caisson is verified at the highest possible water level during sinking construction and use. Without considering the frictional resistance of the soil outside the caisson wall, the lower limit of the anti-floating stability coefficient is 1.0 to ensure the anti-floating stability requirements of the caisson; if the caisson is deeper, frictional resistance should be considered and the anti-floating stability coefficient should be 1.15; when grouting measures are used between the outer wall of the caisson and the soil, 1.05 can be used), and recommended reinforcement parameters based on the loads, where the loads specifically include the deadweight of the structure, external soil pressure, external water pressure, ground live load, net reaction of the bottom plate, etc.

[0046] Optimally, parametric algorithms allow users to quickly input parameters through an interface, avoiding the tedious process of manual modeling and significantly improving design efficiency. Parameters are divided into fixed and variable parameters, supporting dynamic adjustment and updating of models to meet the needs of different scenarios. This method uses geometric constraint rules (such as automatic adjustment of wellbore wall thickness with inner and outer diameters) to ensure the mathematical relationship between parameters is reasonable, reducing human error. It also performs validation checks on input parameters (such as negative value interception and geometric conflict detection) to avoid generating models that do not meet actual requirements or engineering specifications. Finite element methods are used to verify mechanical properties (e.g., crack width ≤ 0.2 mm, anti-floating stability coefficient ≥ 1.15) to ensure that the model meets structural safety requirements.

[0047] S200: Generate a three-dimensional model of the underground power tunnel using the design-related parameters of the underground power tunnel that have passed the inspection.

[0048] Specifically, the corresponding parametric template is called according to the input tunnel type, and the parametric template includes at least one of cast-in-place multi-layer multi-compartment open-cut working shaft, multi-layer multi-compartment caisson, jacking pipe, drainage pipe, box culvert, cable trench, shield, dark-cut tunnel, dark-cut well, and vertical shaft.

[0049] Preferably, the contour lines and path lines are generated based on the input geometric size parameters based on geometric constraint rules. The geometric constraints here refer to the geometric shape definition rules of the basic three-dimensional model.

[0050] Furthermore, the graphics engine's stretching function stretches the outline into a basic 3D solid model. This basic 3D solid model is then bound to parameters related to the power tunnel design, such as the wall thickness, which is controlled by the variable layerWallThickness. Whenever the power tunnel design parameters are modified, the basic 3D solid model automatically updates based on the bound parameters and dependencies.

[0051] Furthermore, wall and slab reinforcement structures are added to the basic three-dimensional solid model.

[0052] Preferably, the reinforcement structure includes general reinforcement parameters and modeling logic, which can automatically calculate the anchoring direction and anchoring length and generate a reinforcement model.

[0053] Furthermore, according to the input reinforcement parameters, a corresponding reinforcement template is selected; the geometric compatibility of the selected reinforcement template and the input reinforcement parameters with the basic three-dimensional solid model is checked, where the geometric compatibility refers to the dynamic adjustment rules between the reinforcement position and the size of the basic three-dimensional solid model; based on the selected reinforcement template and the input reinforcement parameters, a three-dimensional reinforcement structure is generated; the three-dimensional reinforcement structure is dynamically associated with the basic three-dimensional solid model to generate a three-dimensional model of the underground power tunnel.

[0054] Furthermore, auxiliary facilities are inserted into the basic three-dimensional solid model, and reinforcement is arranged to generate a three-dimensional model of the underground power tunnel.

[0055] Furthermore, feature extraction algorithms are used to identify the geometric features of embedded parts and match their types accordingly. Customized accessory parameter templates are then dynamically associated with the 3D model of the underground power tunnel via a graphics engine. Dynamically associating the 3D reinforcement structure with the underlying 3D solid model involves dynamically adjusting the reinforcement position as the underlying 3D solid model changes in size. Spatial interference between the reinforcement and accessory facilities is detected, triggering automatic avoidance or prompting for modification if a conflict occurs.

[0056] Furthermore, it supports flexible and diverse addition of ancillary facilities, including embedded models such as well holes, pipe holes, pull ring pits, sump pits, Halfen troughs, U-shaped pull rings, steel ladders, etc. It also supports the creation of user-defined accessories, as well as parametric reinforcement of different side panels, beams, columns, well holes, blade feet and other parts.

[0057] Furthermore, the finite element method is used to calculate the maximum load borne by concrete components, and reinforcement parameters are recommended based on the maximum load; the maximum width of concrete cracks, shear bearing capacity, anti-floating stability coefficient, foundation bearing capacity, etc. are verified through the recommended reinforcement parameters.

[0058] Furthermore, genetic algorithms are used to automatically optimize information at different depths and soil layers, and recommend information such as wall thickness and reinforcement parameters.

[0059] Preferably, this solution can call the corresponding parametric template according to the input tunnel type (such as cast-in-place multi-layer multi-compartment open-cut working shaft, multi-layer multi-compartment caisson, jacking pipe, drainage pipe, box culvert, cable trench, shield, dark-excavated tunnel, dark-excavated shaft, vertical shaft), support a variety of application scenarios, and can generate contour lines and path lines based on geometric constraint rules, and quickly create basic three-dimensional solid models through the graphics engine stretching function, which is easier to use and reduces the professional requirements for users; binding the model with parameters so that the model is automatically updated synchronously when the parameters are modified, thereby improving the efficiency of design iteration; in particular, the reinforcement structure contains general reinforcement parameters and modeling logic, which can automatically calculate the anchoring direction and length, generate a steel bar model, and improve the accuracy and efficiency of reinforcement design; it can also perform compatibility checks on the reinforcement to ensure that the reinforcement position and the basic three-dimensional solid model size are dynamically adjusted to avoid spatial interference.

[0060] This solution also supports the creation of custom ancillary facilities, meeting the individual needs of complex engineering scenarios. Users simply enter key parameters for these custom ancillary facilities (such as size, location, and material), and the system automatically generates a corresponding model, eliminating the time-consuming process of traditional manual modeling. Custom facilities can also be saved as templates (such as special sump designs) and directly applied to subsequent projects, effectively reducing duplication of work.

[0061] S300: Based on the 3D model of the underground power tunnel, a 2D drawing of the underground power tunnel is generated through a cutting plane algorithm, and corresponding dimension annotations and a bill of materials are automatically added to the 2D drawing of the underground power tunnel.

[0062] Specifically, generating a two-dimensional drawing of an underground power tunnel through a cutting plane algorithm includes: defining a cutting plane and determining the position and direction of the cutting plane; preprocessing the three-dimensional model of the underground power tunnel, calculating the intersection points of the edges of the three-dimensional model of the underground power tunnel and the cutting plane, and connecting all intersection points to form intersection lines; closing the intersection lines to generate a section polygon; and automatically adding at least one of dimension annotations, leader annotations, and text annotations based on the section polygon.

[0063] Furthermore, the material list includes but is not limited to the amount of concrete and the weight of steel bars. The amount of concrete is calculated based on the volume of the three-dimensional model of the underground power tunnel, and the weight of steel bars is calculated based on the length, number, nominal diameter and theoretical weight of each bar.

[0064] Furthermore, it supports exporting underground power tunnel two-dimensional drawings into common formats such as DXF and DWG, which facilitates compatibility with other software and meets the actual needs of engineering design.

[0065] Preferably, by defining the cutting plane and calculating the intersection, the section polygon is automatically generated, which simplifies the conversion process from the three-dimensional model to the two-dimensional drawing; the dimension annotation, leader annotation and text annotation can be automatically added, which reduces the workload of manual annotation while ensuring the accuracy of the annotation; the material list (such as the amount of reinforced concrete and the embedded parts list) can be automatically generated on the two-dimensional drawing, providing a complete design basis for construction.

[0066] S400: Output the underground power tunnel 3D model file and the underground power tunnel 2D drawing file.

[0067] Specifically, the point and surface coordinate data of the model are obtained through the H3D graphics engine and constructed into text files in multiple common model formats. The IGES format calls the open source OCC library for format conversion.

[0068] Furthermore, the software supports exporting 3D underground power tunnel models to various common formats, including OBJ, STL, STP, and IGES, for loading and display in other software. It also generates 2D drawings using model sections, including 2D design drawings, reinforcement diagrams, embedded parts material lists, reinforced concrete material tables, etc. It supports automatic dimensioning and text annotation, and supports exporting to DXF and DWG files.

[0069] The present invention also provides a parametric design method system for an underground power tunnel, which is used to implement the parametric design method for an underground power tunnel. The system includes a control module, which includes a memory, a processor, and a computer program stored in the memory and runnable on the processor. The processor executes the computer program to implement the parametric design method for an underground power tunnel.
