Description

Technical Field

[0001] This invention belongs to the field of digital design of mining engineering; in particular, it relates to a method for designing roadway cross sections based on parametric models and rule constraints. Background Technology

[0002] In mine tunnel engineering design, cross-section design is a fundamental and crucial step. Traditional design methods heavily rely on the experience of designers, determining cross-sectional shapes, support methods, and facility layouts through consulting manuals, manual calculations, and repeated sketching. This approach is cumbersome, inefficient, and struggles to ensure the uniformity of design standards and the compliance of layout schemes. Especially when dealing with tunnels containing complex transportation systems, multiple pipelines, and cables, problems such as pipeline conflicts and insufficient safety clearances are prone to arise. While some existing auxiliary tools can improve drawing efficiency, they fail to integrate design specifications, data-driven approaches, and intelligent review throughout the entire design process. Summary of the Invention

[0003] The purpose of this invention is to provide a roadway cross-section design method based on parametric models and rule constraints.

[0004] This invention is achieved through the following technical solution:

[0005] This invention relates to a method for designing roadway cross-sections based on parametric models and rule constraints, comprising the following steps:

[0006] Step 1: Construct a multi-level parametric design model: This model deconstructs the tunnel cross-section into three interrelated design levels: geometric profile layer, ancillary facilities layer, and support system layer.

[0007] Step 2: Establish a design rule knowledge base: Transform the tunnel cross-section design specifications and safety regulations into calculable constraints;

[0008] Step 3: Implement the linkage mechanism of parameters, rules, and graphics: Users define design elements at each level through parameterization in a unified interface. The system performs compliance verification based on the rule knowledge base and converts the verified design parameters into standardized engineering drawings and statistical reports.

[0009] Preferably, in step 1, the geometric contour layer is the basic spatial framework of the design, used to define the basic shape and dimensional constraints of the tunnel cross-section.

[0010] Preferably, the geometric contour layer encapsulates the cross-sectional shape and key geometric parameters such as net width, wall height, arch height, concrete spraying thickness, masonry thickness, foundation depth, and bottom paving thickness.

[0011] Preferably, in step 1, the ancillary facilities layer is a collection of entities that carry specific functions of the roadway, used to define the physical components required for drainage ditches, steps, pipe trenches, door facilities, and transportation, ventilation, water supply and drainage, and power supply systems.

[0012] Preferably, the ancillary facilities layer abstracts various facilities into independent, parameter-configurable object models, each object containing its orientation, location, specifications, and size attributes.

[0013] Preferably, in step 1, the support system layer is a structural system that ensures the stability of the surrounding rock of the roadway, and is used to define the support form and support materials.

[0014] Preferably, the support system layer abstracts anchor bolts, anchor cables, nets, composite components, and reinforcement into parameterized objects, and supports the combined definition of support component parameters and strengths.

[0015] Preferably, in step 2, the rule knowledge base includes:

[0016] (1) Spatial layout rules: the safe distance between the outermost edge of the equipment and the side or top of the alley, the minimum clear distance between facilities, and the width requirements of the sidewalk;

[0017] (2) Parameter matching rules: the correspondence between support parameters and surrounding rock type, the matching relationship between cross-sectional dimensions and ventilation requirements, and the correspondence between step dimensions and tunnel inclination angle;

[0018] (3) Construction and process rules: track type and gauge, thickness of steel reinforcement protective layer, anchor bolt (cable) type, exposed length and anchoring form.

[0019] Preferably, in step 3, the specific process of the parameter-rule-graphic linkage driving mechanism is as follows:

[0020] (1) Parametric-driven design: Users can assign parameter values ​​and instantiate the three-level design model through a unified design interface by filling in the selections;

[0021] (2) Real-time verification under rule constraints: When a user modifies any design parameters, the design engine calls the relevant constraints in the rule knowledge base to verify the compliance of the current design scheme;

[0022] (3) Output: After the design scheme passes the verification, the design engine can perform the following operations based on the complete parametric model:

[0023] (3.1) Graphic conversion: Without manual intervention, the parametric model is mapped into a two-dimensional graphic that conforms to engineering drawing standards, and the tunnel cross-section diagram is output with one click;

[0024] (3.2) Data statistics: Based on the model parameters and geometric relationships, the engineering quantities are automatically calculated, and a tunnel cross-section feature table and a material consumption table are generated;

[0025] (3.3) Data fusion: All verified design parameters, geometric information and statistical results are dynamically stored as structured metadata and can be linked with the output tunnel centerline graphic elements to form a digital design asset that integrates graphics and data.

[0026] Preferably, the verification scope includes multiple dimensions such as spatial conflict, parameter rationality, and specification compliance.

[0027] The present invention has the following advantages:

[0028] (1) Innovative method and principle: A new paradigm for roadway cross-section design, namely “model deconstruction-rule encoding-linkage driving”, was proposed, which elevates the design from empirical drawing to knowledge-based parametric modeling.

[0029] (2) Controllable design quality: Intelligent verification during the process is achieved through the built-in computable rule base, which fundamentally ensures the compliance and engineering rationality of the design scheme and significantly reduces the risk of design errors.

[0030] (3) Increased work efficiency: Parametric drive enables rapid iteration and modification of design, and automates repetitive tasks such as drawing and quantity calculation, greatly improving design efficiency.

[0031] (4) Data value extension: The "data-map integration" output is a structured digital asset that enables the lossless transfer and reuse of design data to construction and management processes, laying the core data foundation for digital management of the entire life cycle of mines. Attached Figure Description

[0032] Figure 1 This is a flowchart of the tunnel cross-section design method based on parametric models and rule constraints involved in this invention. Detailed Implementation

[0033] The present invention will now be described in detail with reference to specific embodiments. It should be noted that the following embodiments are merely further illustrations of the present invention, but the scope of protection of the present invention is not limited to the following embodiments.

[0034] Example

[0035] This embodiment relates to a roadway cross-section design method based on parameterized driving and rule constraints, see... Figure 1 As shown, this can be implemented using a dedicated design system integrated into a CAD platform (such as MicroStation, AutoCAD, etc.). The following example of a typical tunnel cross-section design process illustrates the implementation steps of this method.

[0036] S1: Start the parametric design process and initialize the model.

[0037] When a user launches the design system, the system loads a pre-built parametric design model framework and a design rule knowledge base. The user then enters the tunnel cross-section design module through the system's main interface, which presents a unified parametric design interface. This interface logically integrates functions such as geometric definition, facility configuration, and support design, providing a unified entry point for subsequent steps.

[0038] S2: Define the tunnel geometry and basic properties

[0039] In the "Basic Parameters" area of ​​the interactive interface, users can assign values ​​to the geometric contour layer model by selecting or entering parameters.

[0040] Selecting engineering attributes such as tunnel type (e.g., horizontal tunnel, inclined tunnel), ventilation type (e.g., intake air, return air), and surrounding rock type will have a ripple effect on the attribute settings of other objects in subsequent steps. For example, the selection of tunnel type will affect the setting of drainage ditches, and the selection of ventilation type will affect the placement of equipment.

[0041] Select a cross-sectional shape (such as rectangle or semi-circular arch) from the predefined shape library.

[0042] Enter or adjust key dimensional parameters, such as net width and wall height.

[0043] Based on the input, the system provides real-time visual updates of the cross-sectional profile preview, offering instant feedback to the user.

[0044] S3: Configuration of ancillary facilities for the tunnel

[0045] When a user enables the "Facility Configuration" function, the system expands the parameter configuration panel for the ancillary facility layer. In this panel, the user can:

[0046] By using the "Add Object" option, select the type of facility to be deployed from the facility library, such as ditches, pipe trenches, transportation equipment, pipelines, cables, etc.

[0047] For each added facility object, set its specific model specifications (such as track gauge and pipe diameter) and installation parameters (such as height from the bottom plate and distance from the tunnel side).

[0048] Based on the spatial constraint rules in the design rule knowledge base, the system provides prompts during the user configuration process to assist in making reasonable spatial layouts.

[0049] S4: Define the tunnel support system

[0050] When a user enables the "Support Design" function, the system expands the parameter configuration panel for the support system layer. In this panel, the user can:

[0051] The support method is determined by combining different support materials. For example, anchor bolts + metal mesh + shotcrete is called anchor-mesh-shotcrete support.

[0052] Define in detail the material specifications (diameter, length) and layout parameters (arrangement, spacing, angle) of the selected support components (such as (grouting) anchor bolts and anchor cables).

[0053] S5: Perform rule-based design reviews

[0054] At any stage of the design process, users can trigger the "Design Review" feature. The system then invokes the rules engine to perform a full validation of the currently constructed complete parametric model (containing all data defined in S2-S4). The validation process is executed automatically based on rules in the knowledge base, for example:

[0055] Check whether the spatial relationships between all facilities and between them and the roadway outline meet the safety clearance requirements.

[0056] Verify whether the support parameters are compatible with the currently set surrounding rock type.

[0057] The review results are fed back via command line, indicating whether the item is "compliant," "warning," or "conflict" and the basis for such warnings, guiding users to make targeted modifications.

[0058] S6: Binding Design Data to Generate Digital Assets

[0059] Once the design scheme has passed review or been confirmed by the user, the user performs a "data binding" operation. The system prompts the user to specify a graphic element (such as a line segment) representing the central axis of the tunnel. Subsequently, the system uses all validated structured design data (geometric parameters, facility list and parameters, support system parameters) from the current parametric model as an attribute set and fully associates them with this graphic element. At this point, the graphic element is upgraded into an "intelligent tunnel object" carrying complete engineering information, achieving deep integration of graphics and data.

[0060] S7: Automated output of standardized design results

[0061] Based on the "intelligent tunnel object" created by S6, users can drive the system to automatically generate a number of standardized results:

[0062] Automatic drawing generation: The system parses all the attributes of the object, calls the corresponding graphical template, and automatically draws a tunnel cross-section drawing (book) that conforms to industry drawing standards at the specified location.

[0063] Automatic quantity calculation and table generation: The system automatically calculates the engineering quantity based on information such as geometric dimensions, component parameters and material layout density in the attributes, and generates engineering reports such as "tunnel cross-section characteristic table" and "material consumption per meter table".

[0064] Data storage: All design data and calculation results can be stored in a structured manner to generate bills of materials, cost estimates, or be directly imported into downstream construction and management information systems.

[0065] This invention proposes a new paradigm for roadway cross-section design based on "model deconstruction - rule encoding - linkage driving," elevating design from experience-based drawing to knowledge-based parametric modeling. Through a built-in computable rule base, it achieves intelligent verification during the design process, fundamentally ensuring the compliance and engineering rationality of the design scheme and significantly reducing the risk of design errors. Parametric driving enables rapid iteration and modification of the design, and automates repetitive tasks such as drawing and quantity calculation, greatly improving design efficiency. The "integrated drawing and data" output of this invention is a structured digital asset, enabling lossless transfer and reuse of design data to construction and management stages, laying a core data foundation for digital management throughout the entire lifecycle of mines.

[0066] The specific embodiments of the present invention have been described above. It should be understood that the present invention is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the essence of the present invention.
