However, tunnel design and construction face numerous challenges, especially under complex geological conditions, where ensuring tunnel safety, economy, and construction efficiency becomes crucial.

[0028] Figure 2 This is a block diagram of a tunnel intelligent design system according to the present invention. Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The specific embodiments described herein are merely used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] This invention provides an intelligent tunnel design method. First, a preliminary geological environment description is formed based on input geographic location data and geological parameters. Then, at least two tunnel design schemes with different orientations and cross-sectional shapes are created based on these descriptions and a knowledge base, and structural stability and construction feasibility analyses are performed on each scheme. Next, the design schemes are scored and ranked using a preset scoring standard, and the highest-scoring design scheme is selected as the preferred scheme, generating a detailed structural diagram based on it. Subsequently, a three-dimensional digital model of the preferred scheme is constructed using the detailed structural diagram, and virtual construction simulation is performed to identify potential construction difficulties. Design details are adjusted based on the identified problems to form an improved design scheme. This invention can select the most suitable tunnel design scheme through geological data analysis and automatic evaluation of multiple schemes, and avoid risks in advance through virtual construction simulation, effectively reducing changes and rework during construction, thereby shortening the construction period and reducing costs. Specifically:

[0031] like Figure 1 As shown, the intelligent tunnel design method in this embodiment includes the following steps:

[0032] S1: Input tunnel location data and geological parameters A preliminary description of the geological environment was formed through analysis. f represents the process of geological environment formation;

[0033] Furthermore, the preliminary geological environment description includes: collecting topographic and geomorphological information of the proposed tunnel location; combining the topographic and geomorphological information with data on geological structure, rock characteristics, topography, hydrogeological conditions, and climate factors to determine geological stability factors; analyzing the geological stability factors and conducting a geological hazard risk assessment to identify potential geological risk areas; and based on the identified geological risk areas, formulating corresponding risk mitigation measures and incorporating them into the geological environment description.

[0034] The specific steps for this stage are as follows:

[0035] Topographic and geomorphological information collection: Using remote sensing satellite imagery, aerial photogrammetry and other technical means, topographic and geomorphological information of the proposed tunnel area is obtained, including but not limited to changes in ground elevation, slope, aspect, and natural vegetation cover.

[0036] Stratigraphic and Groundwater Data Collection: Combining topographic and geomorphological information, geological drilling is conducted to obtain key geological parameters such as stratigraphic and soil properties, underground structural characteristics, and groundwater levels. The collected stratigraphic and groundwater data are analyzed to determine the main geological factors affecting the stability of the tunnel project, such as weak interlayers, fault fracture zones, and groundwater pressure.

[0037] Geological stability factor analysis: Based on the above information, professional geological software and engineering analysis methods are used to comprehensively analyze geological stability factors and assess their impact on the tunnel project. Potential geological risk areas are identified, such as sections prone to collapse and areas at risk of water inrush.

[0038] Risk mitigation measures development: For identified geological risk areas, corresponding risk mitigation measures are developed. For example, reinforcement and support measures are implemented in landslide-prone areas, and waterproof curtains or drainage systems are installed in areas prone to water inrush. These risk mitigation measures are incorporated into the geological environment description to provide a basis for subsequent design scheme development.

[0039] This series of steps ensures that the preliminary geological environment description is comprehensive and accurate, laying a solid foundation for subsequent tunnel design work.

[0040] S2: Based on the preliminary geological environment description E geo Based on the knowledge base formed by existing projects, create at least two different paths for P. i and cross-sectional shape C i Tunnel design scheme S i For each tunnel design scheme, structural stability, construction feasibility, and economic analysis are conducted to evaluate its applicability: S i =g(E geo ,P i C i ), A i=h(S i ), g represents the process of creating a design solution, and h represents the process of evaluating its applicability;

[0041] Specifically, the knowledge base contains experience data and relevant information from past projects to support designers in creating at least two tunnel design schemes with different orientations and cross-sectional shapes based on preliminary geological descriptions. The knowledge base may include, but is not limited to, the following aspects:

[0042] Historical project data: Data on geology, design, construction, maintenance, and other aspects of similar projects completed in the past can provide reference and guidance for the design of new projects.

[0043] Design specifications and standards: Domestic and international tunnel design-related specifications, standards and technical guidelines to ensure that the design schemes comply with industry standards.

[0044] Materials Performance Database: Data on the physical and chemical properties of various building materials to help designers select the most suitable materials for specific geological conditions.

[0045] Construction technology and processes: Characteristics, applicable scope, construction process, common problems and solutions of various tunnel construction technologies, etc., to provide technical support for design.

[0046] Risk management information includes, but is not limited to, geological hazard risk assessment, construction risk assessment, and emergency response plans, which help designers identify potential risks and take preventive measures.

[0047] Cost estimation model: Based on historical project data, the cost estimation model helps designers make a rough estimate of costs during the design phase, which facilitates cost-benefit analysis.

[0048] Environmental Impact Assessment: The potential impacts of tunnel construction on the surrounding environment and mitigation measures, ensuring that the design scheme meets environmental protection requirements.

[0049] The knowledge base not only provides rich information resources, but also, through intelligent methods, enables the rapid application of this information to new design solutions, thereby improving design efficiency and accuracy. In specific implementations, the composition and application of the knowledge base play a crucial role in creating multiple design solutions, evaluating the applicability of solutions, selecting the optimal solution, and subsequent design optimization.

[0050] Furthermore, at least two tunnel design schemes with different orientations and cross-sectional shapes are created, including: determining possible tunnel orientation options based on the preliminary geological environment description, and then designing multiple cross-sectional shapes to adapt to different geological conditions by combining the tunnel orientation options; simulating the stability of the tunnel structure under specific geological conditions based on the cross-sectional shapes, analyzing the simulation results, and selecting the design scheme with higher structural stability; conducting a cost-benefit analysis on the selected design schemes to determine their economic feasibility, and selecting at least two feasible tunnel design schemes based on the comprehensive cost-benefit analysis results.

[0051] Determining possible tunnel routes: Based on the topographic information and geological stability factor analysis results in the preliminary geological environment description, and considering factors such as topographic conditions, geological structure, and groundwater level, several possible tunnel routes are determined.

[0052] Designing multiple cross-sectional shapes to adapt to different geological conditions: Taking into account factors such as tunnel alignment options, geological conditions, and groundwater hydrological data, multiple cross-sectional shapes are designed to ensure the tunnel structure can adapt to different geological conditions. The design of the cross-sectional shape should fully consider the feasibility of construction technology, such as circular, rectangular, or other customized shapes.

[0053] Simulating the stability of tunnel structures under specific geological conditions: Using specialized software tools, simulations are performed on each cross-sectional shape to analyze its structural stability under specific geological conditions. The simulation results are evaluated to select design schemes with higher structural stability.

[0054] Furthermore, structural stability, construction feasibility, and economic analysis are conducted for each tunnel design scheme, including: analyzing the ground stress distribution of each selected tunnel design scheme to assess its structural stability; checking whether the support structure in the design scheme meets safety requirements based on the analysis results; assessing potential risk points during tunnel excavation based on the inspection results; analyzing the identified risk points, determining the special treatment measures required for the construction stage, and comprehensively evaluating the actual construction feasibility of each design scheme based on the determined special treatment measures.

[0055] In-situ stress distribution analysis: In-situ stress distribution analysis is performed for each selected tunnel design scheme to assess its structural stability. Numerical simulation methods, such as finite element analysis, are used to predict the distribution of in-situ stress under different geological conditions.

[0056] Inspect the support structure in the design scheme: Based on the results of the ground stress distribution analysis, check whether the support structure in the design scheme meets the safety requirements. Assess potential risks during tunnel excavation, such as collapse risk and groundwater pressure.

[0057] Determine the special treatment measures required during the construction phase: Analyze the identified risk points and determine the special treatment measures required during the construction phase. Special treatment measures may include, but are not limited to, reinforcement and support, waterproof curtains, and drainage systems.

[0058] Comprehensive Feasibility Assessment: Based on the determined special treatment measures, a comprehensive assessment of the actual construction feasibility of each design scheme is conducted. Factors such as construction technical difficulty, construction cost, and construction period are considered to ensure that the design scheme is both safe and economical.

[0059] Through this series of steps, it can be ensured that the tunnel design scheme not only takes into account the characteristics of the geological environment, but also fully considers the actual needs and constraints in the construction process, providing strong support for the subsequent selection of the best scheme.

[0060] Furthermore, in intelligent tunnel design methods, economic analysis is a crucial component in evaluating tunnel design schemes. The specific details are as follows:

[0109] Through the above steps, economic analysis can comprehensively evaluate the economic feasibility of different tunnel design schemes, providing a scientific basis for the final selection of the optimal scheme.

[0110] S3: Combining the evaluation results A i Based on a multi-dimensional intelligent scoring system and scoring principles, a scoring standard W suitable for the current tunnel design is formulated. Each design scheme is scored and ranked R. According to the ranking results, the design scheme with the highest score is selected as the preferred scheme S. opt And based on the preferred scheme, generate a detailed structure diagram Dstr; , , 'generate' refers to the sorting process:

[0111] Furthermore, a preset scoring standard is used to score and rank each design scheme, including: assigning a structural stability score to each design scheme based on the evaluation results; assigning a construction feasibility score to each design scheme based on the structural stability score; calculating an overall score for each design scheme based on the feasibility score and taking into account cost-benefit factors; ranking all design schemes according to the overall score; and then selecting the design scheme with the highest ranking as the preferred scheme.

[0112] A structural stability score is assigned to each design scheme: Based on the analysis of ground stress distribution and the safety assessment of the support structure, a structural stability score is assigned to each design scheme. The structural stability score reflects the stability level of the design scheme under specific geological conditions; generally, a higher score indicates a more stable structure.

[0113] Assign a construction feasibility score to each design scheme: Based on the assessment results of the degree of need for special treatment measures and construction risk points, assign a construction feasibility score to each design scheme. The construction feasibility score reflects the feasibility and ease of construction of the design scheme in the actual construction process; a higher score means that construction is simpler and more feasible.

[0114] The feasibility score is based on a comprehensive consideration of cost-benefit factors: The structural stability score is combined with the construction feasibility score, and the results of the cost-benefit analysis are taken into account to calculate an overall score for each design scheme. The overall score should comprehensively consider factors such as safety, ease of construction, and economic benefits.

[0115] Rank all design schemes according to the overall score: Based on the overall score calculated above, rank all design schemes. The ranking result will help us quickly identify the best design scheme.

[0116] The highest-ranked design scheme is selected as the preferred scheme: From the ranking results, the design scheme with the highest score is chosen as the preferred scheme. The preferred scheme should demonstrate the best performance in terms of structural stability, construction feasibility, and economic benefits.

[0117] Furthermore, generating a detailed structural diagram based on the preferred scheme includes: determining the design scheme with the highest score according to the ranking results; formulating a detailed structural layout scheme based on the determined design scheme; drawing the specific dimensions and shapes of each component according to the layout scheme; and generating a complete and detailed structural drawing by combining the specific dimensions and shapes.

[0118] Identify the highest-scoring design: Based on the ranking results, identify the design with the highest score.

[0119] Based on the determined design scheme, a detailed structural layout plan is developed: This plan includes key elements such as the tunnel's orientation, cross-sectional shape, support structure, and drainage system. The structural layout plan needs to fully consider factors such as geological conditions, construction technology, and cost control.

[0120] Draw the specific dimensions and shapes of each component: Based on the layout plan, draw the specific dimensions and shapes of each component. This includes, but is not limited to, important components such as tunnel lining, support system, and drainage facilities.

[0121] Generate complete and detailed structural drawings: Using professional CAD software, create complete structural drawings that take into account the specific dimensions and shapes. The drawings should clearly indicate the location, dimensions, material specifications, and construction details of each part.

[0122] Through this series of steps, we can ensure that the final selected optimal solution not only performs well in terms of structural stability, construction feasibility, and economic benefits, but also has detailed and accurate technical drawings, providing a solid foundation for subsequent construction implementation.

[0123] S4: Utilizing detailed structural diagram D st A three-dimensional digital model M3D of the preferred scheme is constructed, and virtual construction simulations (VS) are performed on it under various tunnel construction techniques to identify the corresponding potential construction difficulties (N). i By comparing and analyzing the construction difficulties and risks associated with different processes, the corresponding design details in the optimal solution are adjusted to form the improved design solution Sopt′. , , Adjust is the process of building a 3D model;

[0124] Furthermore, constructing the three-dimensional digital model of the preferred solution includes: using the detailed structural diagram, starting the three-dimensional modeling software and creating a new project; importing the detailed structural diagram as a reference in the newly created project, and drawing the basic framework of the three-dimensional model according to the reference diagram; gradually adding details according to the basic framework until the entire three-dimensional model is completed, and checking the consistency between the three-dimensional model and the detailed structural diagram.

[0125] Launch 3D modeling software and create a new project: Use professional 3D modeling software (such as AutoCAD, Revit, Navisworks, etc.) to create a new project file according to project requirements.

[0126] Import detailed structural drawings as reference: Import detailed structural drawings into the 3D modeling software as reference drawings. These drawings contain specific dimensions and shape information of the tunnel and its ancillary structures.

[0127] Draw the basic framework of the 3D model: Based on the detailed structural diagram, first draw the basic framework of the 3D model, including the main structure and main supporting structures of the tunnel. You can start by building simple geometric shapes and gradually refine them to more complex structures.

[0128] Gradually add details until the entire 3D model is complete: Building upon the basic framework, gradually add more details, such as drainage, ventilation, and lighting systems. Ensure that every part of the 3D model conforms to the requirements of the detailed structural drawings.

[0129] Check the consistency between the 3D model and the detailed structural drawings: Verify that the 3D model fully conforms to the design requirements in the detailed structural drawings. Verify that the position, size, and shape of each structural component are accurate.

[0130] Furthermore, identifying potential construction difficulties includes: based on the established 3D digital model, launching a virtual construction simulation environment, setting the construction sequence and schedule in the virtual construction simulation environment, and simulating the construction process; observing each construction stage in the simulation process according to the set schedule, and recording any potential construction difficulties that arise based on the observation results.

[0131] Launch the virtual construction simulation environment: Activate the virtual construction simulation function in 3D modeling software or dedicated construction simulation software. Set the parameters for the construction simulation, such as construction sequence, construction machinery, and labor allocation.

[0132] Establish a construction sequence and schedule: Based on the project plan, establish a reasonable construction sequence and schedule, taking into account the interdependencies between different construction phases.

[0133] Simulate the construction process: Follow the set schedule to simulate the entire construction process. Observe each stage of the construction simulation and pay attention to potential problems.

[0134] Record potential construction challenges: Record any potential construction challenges during the simulation. These challenges may include space constraints, conflicting construction sequences, logistical issues, etc.

[0135] Specifically, based on the established 3D digital model, a virtual construction simulation environment is launched. Within this environment, the construction sequence and schedule are set to simulate the entire construction process. During the simulation, each construction stage will proceed according to the set schedule. At this time, the observer needs to closely monitor any problems that may arise during the simulation.

[0136] For example, during the initial excavation phase of the simulation, the risk of rock collapse due to unstable geological conditions may be discovered. Or, during the simulation of installing support structures, it may be found that space constraints prevent certain heavy equipment from reaching designated locations, thus affecting the construction progress. Furthermore, during the simulation of drainage system installation, it may be discovered that the originally designed drainage path does not match the actual geological structure, leading to problems such as poor drainage.

[0137] The observations above need to be recorded in detail. The record should include the construction stage, specific location, anticipated problems, and possible cause analysis. Such records will help the design team understand the nature of potential difficulties and provide a basis for developing the next step of the solution.

[0138] After the data is recorded, the design team will analyze the root causes behind potential difficulties based on the recorded information and propose targeted solutions. For example, if the risk of rock collapse is due to unstable geological conditions, it may be necessary to strengthen the support structure or change the excavation method; if it is a space constraint problem, it may be necessary to re-plan the equipment transportation route or select smaller but equally efficient equipment; for the problem of poor drainage, it is necessary to re-evaluate the drainage path and may be necessary to adjust the design to ensure smooth water flow.

[0139] By following these steps, potential construction challenges can be effectively identified and resolved, ensuring that the final design is both safe, reliable, and cost-effective. Furthermore, virtual construction simulations can help identify and mitigate potential problems during actual construction, thereby improving both efficiency and quality.

[0140] Furthermore, the corresponding design details in the preferred scheme are adjusted to form an improved design scheme, including: listing the design details that need to be adjusted based on the identified construction difficulties, and re-evaluating their impact on the overall design based on the listed design details; making corresponding adjustments to the preferred scheme based on the evaluation results, and generating detailed structural diagrams again; and constructing a three-dimensional digital model of the improved design scheme based on the updated detailed structural diagrams.

[0141] List the design details that need adjustment: Based on the identified construction difficulties, list all design details that need adjustment. Analyze the impact of these details on the overall design.

[0142] Reassess its impact on the overall design: Re-evaluate the listed design details to ensure that modifications do not affect the structural safety and functionality. Consider potential cost changes and other influencing factors that may result from the modifications.

[0143] Make appropriate adjustments to the preferred solution: Based on the evaluation results, make necessary adjustments to the relevant design details in the preferred solution. Ensure that the adjusted design still meets all design requirements.

[0144] Regenerate detailed structural drawings: Based on the revised design, regenerate detailed structural drawings. These drawings will reflect all design changes.

[0145] Build a 3D digital model of the improved design: Using the revised detailed structural drawings, build a 3D digital model of the improved design and check the consistency between the model and the drawings again.

[0146] Through this series of steps, potential construction challenges can be effectively identified and resolved, ensuring that the final design is both safe, reliable, and cost-effective. Furthermore, virtual construction simulation can help identify and mitigate various problems that may arise during actual construction, thereby improving construction efficiency and quality.

[0148] On the other hand, this embodiment proposes a tunnel intelligent design system, such as Figure 2 As shown, it includes: a preliminary geological environment analysis module, a design scheme creation and evaluation module, a scheme selection and structural diagram generation module, a three-dimensional digital model construction and optimization module, and a model output module.

[0149] The design scheme creation and evaluation module is used to create at least two tunnel design schemes with different orientations and cross-sectional shapes based on the preliminary geological environment description and the knowledge base formed by existing projects. It performs structural stability, construction feasibility and economic analysis on each tunnel design scheme and evaluates its applicability.

[0150] The scheme selection and structure diagram generation module is used to combine the evaluation results, formulate a scoring standard suitable for the current tunnel design based on a multi-dimensional intelligent scoring system and scoring principles, score and rank each design scheme, select the design scheme with the highest score as the preferred scheme based on the ranking results, and generate a detailed structure diagram based on the preferred scheme.

[0151] The 3D digital model construction and optimization module is used to construct a 3D digital model of the preferred scheme using detailed structural diagrams, and to conduct virtual construction simulations of it under various tunnel construction processes to identify corresponding potential construction difficulties and risks. By comparing and analyzing the construction difficulties and risks corresponding to different processes, the corresponding design details in the preferred scheme are adjusted to form an improved design scheme.

[0152] The model output module is used to output the improved design scheme and its 3D digital model for selection and implementation.

[0153] The aforementioned modules for preliminary geological environment analysis, design scheme creation and evaluation, scheme optimization and structural diagram generation, three-dimensional digital model construction and optimization, and model output are also used to perform other steps of the aforementioned intelligent tunnel design method, which will not be elaborated here.

[0154] This invention, through the analysis of geological data and the automatic evaluation of multiple schemes, can more accurately select the most suitable tunnel design. By identifying potential risk points through virtual construction simulation, measures can be taken in advance to avoid safety hazards during actual construction. The optimized design scheme can effectively reduce changes and rework during construction, thereby shortening the construction period and reducing construction costs.
