[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.

[0029] The following combines the attached Figure 1 - attached Figure 5 The specific implementation manners of the embodiments of the present invention are described in detail. It should be understood that the specific implementation manners described herein are only used to illustrate and explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention.

[0030] It should be noted that the acquisition, transmission, storage, use, processing, etc. of data in the technical solution of this application all comply with the relevant regulations of national laws and regulations. In the embodiments of this application, some industry-existing solutions such as certain software, components, models, etc. may be mentioned. They should be regarded as exemplary. The purpose is only to illustrate the feasibility in the implementation of the technical solution of this application, but it does not mean that the applicant has already or necessarily used this solution.

[0031] Embodiment 1 Refer to Figure 1 - Figure 5 , which is the first embodiment of the present invention. This embodiment provides a parametric design method and system for an underground power tunnel, including: S100: Receive the parameters related to the design of the underground power tunnel input through a parametric algorithm, and perform multi-constraint verification and parameter correlation check.

[0032] It should be noted that the parametric algorithm calls the H3D graphics engine instead of directly operating on the underlying graphics data.

[0033] The H3D graphics engine is a three-dimensional graphics platform for entity features. It can calculate the parameters and set parameters through the mathematical relationship between the parameters of the conventional entity model and the set parameters, drive the model to update, realize the parameterization of the conventional entity model, draw sketches for unconventional entities, determine the feature entities based on the modeling method of defining sketches, and the corresponding parameters, determine the mathematical relationship between the parameters and the set parameters, calculate the parameters and the set parameters, drive the model to update, and realize the parameterization of the unconventional entity model. This graphics engine realizes the diversified generation and real-time display of the parametric model by constructing a basic graphics library and a visualization model interface.

[0034] Specifically, determine the application scenario and functional requirements according to the design objectives; implement the parametric algorithm through engine functions such as dimension constraints, feature bodies, Boolean operations, and geometric constraint solving. The geometric constraints here refer to the mathematical function relationships between the relevant design parameters of the underground power tunnel.

[0035] Furthermore, identify the input design-related parameters of the underground power tunnel and divide the input design-related parameters of the underground power tunnel into fixed parameters and variable parameters; define the mathematical function relationships between the variable parameters and the fixed parameters to generate dynamically updated geometric constraint rules.

[0036] Furthermore, the user inputs the design-related parameters of the underground power tunnel through the interface, such as geometric dimensions (such as well wall thickness, well length / width / height, pipe diameter), material properties (such as concrete type, steel bar grade, cover thickness), structural parameters (such as number of bins, number of layers), embedded part types (such as well holes, pipe holes, sump pits), and load parameters (soil pressure, groundwater pressure), etc.

[0037] Furthermore, define the dependency relationship, such as the well hole wall thickness automatically adjusts with the inner and outer diameters.

[0038] Furthermore, perform legality detection on the input design-related parameters of the underground power tunnel, including negative value interception, such as popping up a window to prompt "The well wall thickness cannot be negative"; geometric conflict detection, such as popping up a window to prompt "Parameter conflict" when the well hole diameter exceeds the well wall range.

[0039] Furthermore, conduct mechanical verification. Using the finite element method, calculate the crack width (≤0.2mm, representing that the calculated result of checking the concrete crack width should not exceed 0.2mm (GB50010-2010 Code for Design of Concrete Structures)) and anti-floating stability (anti-floating stability coefficient ≥1.15, representing the check carried out with the highest possible water level during the sinking construction and use of the open caisson. Without considering the action of the soil friction resistance on the outer side of the well wall, the lower limit of the anti-floating stability coefficient is taken as 1.0 to ensure the anti-floating stability requirements of the open caisson; if the open caisson is deeper, the friction resistance should be considered and the anti-floating stability coefficient should be taken as 1.15; when grouting measures are adopted between the outer wall of the well and the soil, it can be taken as 1.05), and recommend reinforcement parameters according to the load. Here, the load specifically includes the self-weight of the structure, external soil pressure, external water pressure, ground live load, net reaction force of the bottom plate, etc.

[0040] Preferably, the parametric algorithm allows users to quickly input parameters through the interface, avoiding the cumbersome process of manual modeling and greatly improving the design efficiency. The parameters are divided into fixed parameters and variable parameters, supporting dynamic adjustment and updating of the model to meet the requirements of different scenarios. This method ensures the reasonable mathematical relationship between parameters through geometric constraint rules (such as the wellbore wall thickness automatically adjusting with the inner and outer diameters), reducing human errors, and can perform legality detection on the input parameters (such as negative value interception and geometric conflict detection) to avoid generating models that do not meet the actual requirements or engineering specifications. The finite element method is used for mechanical property verification (such as crack width ≤ 0.2mm, anti-floating stability coefficient ≥ 1.15) to ensure that the model meets the structural safety requirements.

[0041] S200: Generate a three-dimensional model of the underground power tunnel using the qualified relevant parameters for the design of the underground power tunnel.

[0042] Specifically, call the corresponding parametric template according to the input tunnel type. The parametric template includes at least one of in-situ multi-layer and multi-chamber open-cut working wells, multi-layer and multi-chamber caissons, pipe jacking, pipe laying, box culverts, cable trenches, shield tunneling, mined tunnels, mined wells, and vertical shafts.

[0043] Preferably, based on geometric constraint rules, generate a contour line and a path line according to the input geometric dimension parameters. Here, the geometric constraint refers to the geometric shape definition rules of the basic three-dimensional model.

[0044] Furthermore, stretch the contour line into a basic three-dimensional solid model through the stretching function of the graphics engine, and bind the basic three-dimensional solid model to the relevant parameters for the design of the power tunnel. For example, the well wall thickness is controlled by the variable layerWallThickness. When modifying the relevant parameters for the design of the power tunnel, the basic three-dimensional solid model automatically synchronously updates according to the bound parameters and dependencies.

[0045] Furthermore, add wall and slab reinforcement structures to the basic three-dimensional solid model.

[0046] Preferably, the reinforcement structure contains general reinforcement parameters and modeling logic, and can automatically calculate the anchoring direction and anchoring length to generate a reinforcement model.

[0047] Furthermore, select the corresponding reinforcement template according to the input reinforcement parameters; check the geometric compatibility between the selected reinforcement template and the input reinforcement parameters and the basic three-dimensional solid model. Here, the geometric compatibility refers to the dynamic adjustment rules between the reinforcement position and the dimensions of the basic three-dimensional solid model; based on the selected reinforcement template and the input reinforcement parameters, generate a three-dimensional reinforcement structure; dynamically associate the three-dimensional reinforcement structure with the basic three-dimensional solid model to generate a three-dimensional model of the underground power tunnel.

[0048] Furthermore, insert auxiliary facilities into the basic 3D solid model to generate a 3D model of the underground power tunnel with reinforcement.

[0049] Furthermore, identify the geometric features of embedded parts through a feature extraction algorithm, and match the types of embedded parts according to the geometric features of the embedded parts; customize the parameter template of the accessory, and dynamically associate the customized accessory with the 3D model of the underground power tunnel through the graphics engine. Dynamically associating the 3D reinforcement structure with the basic 3D solid model includes: the reinforcement position is dynamically adjusted according to the size change of the basic 3D solid model; detect the spatial interference between the reinforcement and the auxiliary facilities, and if there is a conflict, trigger automatic avoidance or prompt for modification.

[0050] Furthermore, support the addition of flexible and diverse auxiliary facilities, including embedded part models such as well holes, pipe holes, pull ring pits, sump pits, Hafen grooves, U-shaped pull rings, steel ladders, etc., also support users to create customized accessories, and perform parametric reinforcement on different side plates, beams, columns, well holes, blade feet, etc.

[0051] Furthermore, through the finite element method, calculate the maximum load borne by the concrete component, and recommend reinforcement parameters according to the maximum load; verify the maximum crack width, shear bearing capacity, anti-floating stability coefficient, foundation bearing capacity, etc. of the concrete through the recommended reinforcement parameters.

[0052] Furthermore, use the genetic algorithm to automatically optimize the information of different depths and soil layers, and recommend information such as wall thickness and reinforcement parameters.

[0053] Preferably, this solution can call the corresponding parametric template according to the input tunnel type (such as cast-in-place multi-layer multi-chamber open cut working well, multi-layer multi-chamber caisson, pipe jacking, pipe jacking, box culvert, cable trench, shield, mined tunnel, mined shaft, vertical shaft), support multiple application scenarios, and can generate contour lines and path lines based on geometric constraint rules, and quickly create a basic 3D solid model through the stretching function of the graphics engine, which is easier to get started and reduces the professional requirements for users; binding the model with parameters enables the model to be automatically synchronized and updated when the parameters are modified, improving the design iteration efficiency; especially the reinforcement structure includes general reinforcement parameters and modeling logic, which can automatically calculate the anchoring direction and length, generate the reinforcement model, and improve the accuracy and efficiency of the reinforcement design; it can also perform compatibility checks on the reinforcement to ensure that the reinforcement position is dynamically adjusted according to the size of the basic 3D solid model, avoiding spatial interference.

[0054] Preferably, this solution also supports users to create customized auxiliary facilities, which can meet the personalized needs of complex engineering scenarios; and users only need to input the key parameters of the customized auxiliary facilities (such as size, position, material), and the system automatically generates the corresponding model, avoiding the time-consuming operation of traditional manual modeling. The customized facilities can also be saved as templates (such as special sump pit design) and directly called in subsequent projects, which can effectively reduce repetitive labor.

[0055] S300: Generate two-dimensional drawings of the underground power tunnel through the cutting plane algorithm, and automatically add corresponding dimension markings and material lists to the two-dimensional drawings of the underground power tunnel.

[0056] Specifically, generating two-dimensional drawings of the underground power tunnel through the 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 the intersection points to form an intersection line; performing a closing process on the intersection line to generate a sectional polygon; automatically adding at least one of dimension markings, leader markings, and text annotations based on the sectional polygon.

[0057] Furthermore, the material list includes but is not limited to the amount of concrete used and the weight of steel bars. The amount of concrete used is calculated based on the volume of the three-dimensional model of the underground power tunnel, and the weight of steel bars is statistically calculated according to the single length, number of roots, nominal diameter, and theoretical weight.

[0058] Furthermore, it supports exporting the two-dimensional drawings of the underground power tunnel into common formats such as DXF and DWG, which is convenient for compatibility with other software and meets the actual needs of engineering design.

[0059] Preferably, by defining a cutting plane and calculating the intersection points, a sectional polygon is automatically generated, which simplifies the conversion process from a three-dimensional model to two-dimensional drawings; it can automatically add dimension markings, leader markings, and text annotations, reducing the workload of manual markings while ensuring the accuracy of the markings; it can automatically generate a material list (such as the amount of reinforced concrete used and the embedded part list) on the two-dimensional drawings, providing a complete design basis for construction.

[0060] S400: Output the three-dimensional model file and two-dimensional drawing file of the underground power tunnel.

[0061] Specifically, obtain the point and face coordinate data of the model through the H3D graphics engine, and respectively construct text files in various common model formats. For the IGES format, an open-source OCC library is called for format conversion.

[0062] Furthermore, it supports exporting the three-dimensional model of the underground power tunnel into various common formats such as OBJ, STL, STP, and IGES for loading and displaying in other software. The two-dimensional drawings are generated by means of model sections, including two-dimensional design drawings, reinforcement drawings, embedded part material lists, reinforced concrete material tables, etc., support automatic dimension markings and marking texts, and support exporting DXF and DWG files.
