Description

Technical Field

[0001] The present invention belongs to the technical field of engineering design, and in particular relates to a tunnel intelligent design system and method. Background Art

[0002] With the acceleration of urbanization and the increasing demand for infrastructure construction, tunnel engineering plays an increasingly significant role in transportation networks. However, the design and construction of tunnels face many challenges, especially under complex geological conditions. How to ensure the safety, economy and construction efficiency of tunnels has become a key issue. Traditional tunnel design methods often rely on manual experience and limited data analysis, which is not only time-consuming and labor-intensive, but also may have certain risks due to lack of comprehensive consideration.

[0003] At present, in the tunnel design stage, there is a lack of an intelligent design method that can comprehensively consider geological environment characteristics, automatically evaluate multiple design schemes, and quickly iterate and optimize. This leads to the possibility that the selection of design schemes may not be scientific and reasonable enough, and it is difficult to meet the increasingly high requirements of engineering safety and economic benefits.

[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

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

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

[0032] S1: Input the tunnel geographical location data and geological parameters Dgeo, and form a preliminary geological environment description Egeo through analysis: Egeo = f(Dgeo), where f is the process of forming the geological environment description;

[0033] Furthermore, forming a preliminary geological environment description includes: collecting topographic and geomorphic information of the proposed tunnel location; combining the topographic and geomorphic information, collecting data on geological structure, rock characteristics, topography, hydrogeological conditions and climatic 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 of this stage are as follows:

[0035] Collection of topographic information: Use remote sensing satellite images, aerial photogrammetry and other technical means to obtain topographic information of the proposed tunnel area, including but not limited to ground elevation changes, slope, slope direction, natural vegetation coverage, etc.

[0036] Collection of stratigraphic structure and groundwater data: Combined with topographic information, geological drilling work is carried out to obtain key geological parameters such as stratigraphic rock and soil properties, underground structural characteristics, and groundwater levels. The collected stratigraphic structure 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] Analysis of geological stability factors: Based on the above information, use professional geological software and engineering analysis methods to conduct a comprehensive analysis of geological stability factors and assess their impact on tunnel engineering. Identify potential geological risk areas, such as sections prone to collapse and water inrush risk areas.

[0038] Risk mitigation measures: Develop corresponding risk mitigation measures for the identified geological risk areas. For example, take reinforcement support measures in areas prone to landslides, and set up waterproof curtains or drainage systems in water-gushing risk areas. Incorporate these risk mitigation measures into the geological environment description to provide a basis for the subsequent design plan.

[0039] Through this series of steps, it can be ensured that the preliminary description of the geological environment is comprehensive and accurate, laying a solid foundation for subsequent tunnel design work.

[0040] S2: Based on the preliminary geological environment description Egeo and the knowledge base formed by the existing projects, create at least two tunnel design schemes Si with different strikes Pi and cross-sectional shapes Ci, analyze the structural stability, construction feasibility and economy of each tunnel design scheme, and evaluate its applicability: Si = g(Egeo, Pi, Ci), Ai = h(Si), g is the process of creating the design scheme, and h is the process of evaluating the applicability;

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

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

[0043] Design specifications and standards: Domestic and international specifications, standards and technical guidelines related to tunnel design to ensure that the design plan meets industry standards.

[0044] Material properties database: Data on the physical and chemical properties of various building materials to help designers choose the materials most suitable for specific geological conditions.

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

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

[0047] Cost estimation model: The cost estimation model based on historical project data helps designers to have a rough estimate of costs during the design phase, facilitating cost-benefit analysis.

[0048] Environmental impact assessment: The possible impact of tunnel construction on the surrounding environment and its mitigation measures to ensure that the design meets environmental protection requirements.

[0049] The knowledge base not only provides a wealth of information resources, but also can quickly apply this information to new design solutions in an intelligent way, thereby improving design efficiency and accuracy. In a specific implementation, the composition and application of the knowledge base play a key role in creating multiple design solutions, evaluating the applicability of solutions, selecting the best 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 options for tunnel orientation based on the preliminary geological environment description, and then designing a variety of cross-sectional shapes in combination with the tunnel orientation options to adapt to different geological conditions; simulating the stability of the tunnel structure under specific geological conditions based on the cross-sectional shape, and analyzing the simulation results to screen out design schemes with higher structural stability; conducting a cost-benefit analysis on the screened design schemes to determine their economic feasibility, and selecting at least two feasible tunnel design schemes based on the results of the cost-benefit analysis.

[0051] Determine possible options for the tunnel's orientation: Based on the topographic and geomorphic information in the preliminary geological environment description and the results of the geological stability factor analysis, taking into account factors such as terrain conditions, geological structure, and groundwater level, determine multiple possible options for the tunnel's orientation.

[0052] Design a variety of cross-sectional shapes to adapt to different geological conditions: Combine the tunnel orientation options, consider geological conditions, groundwater data and other factors, and design a variety of cross-sectional shapes to ensure that the tunnel structure can adapt to different geological conditions. The design of the cross-sectional shape should fully consider the feasibility of the construction technology, such as round, rectangular or other customized shapes.

[0053] Simulate the stability of tunnel structures under specific geological conditions: Use professional software tools to simulate each cross-sectional shape and analyze its structural stability under specific geological conditions. Evaluate the simulation results and select designs with higher structural stability.

[0054] Furthermore, each tunnel design scheme is analyzed for structural stability, construction feasibility and economy, including: analyzing the ground stress distribution of each selected tunnel design scheme to evaluate its structural stability; combining the analysis results to check whether the support structure in the design scheme meets the safety requirements, and based on the inspection results, evaluating the possible risk points in the tunnel excavation process; analyzing the identified risk points, determining the special treatment measures required in the construction phase, and based on the determined special treatment measures, comprehensively evaluating the actual construction feasibility of each design scheme.

[0055] Geostress distribution analysis: Geostress distribution analysis is performed on each selected tunnel design to evaluate its structural stability. Numerical simulation methods, such as finite element analysis, are used to predict the distribution of geostress under different geological conditions.

[0056] Check the support structure in the design: Combined with the results of the ground stress distribution analysis, check whether the support structure in the design meets the safety requirements. Evaluate the possible risk points during tunnel excavation, such as collapse risk, groundwater pressure, etc.

[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 support, waterproof curtains, drainage systems, etc.

[0058] Comprehensive evaluation of construction feasibility: Based on the determined special treatment measures, comprehensively evaluate the actual construction feasibility of each design solution. Consider factors such as construction technical difficulty, construction cost, and construction period to ensure that the design solution is both safe and economical.

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

[0060] In addition, in the intelligent tunnel design method, economic analysis is an important part of evaluating tunnel design solutions. The specific contents are as follows:

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

[0110] S3: Combined with the evaluation result Ai, a scoring standard W suitable for the current tunnel design is formulated based on a multi-dimensional intelligent scoring system and scoring principles to score and rank each design scheme R. According to the ranking result, the design scheme with the highest score is selected as the preferred scheme Sopt, and a detailed structure diagram Dstr is generated based on the preferred scheme; R = sort(Ai·W)Sopt = argmax(R)Dstr = generate(Dgeo,Sopt), where generate is the sorting process:

[0111] R = sort (Ai·W) Sopt = argmax (R) Dstr = generate (Dgeo, Sopt), generate is the sorting process;

[0112] Furthermore, each design scheme is scored and ranked using a preset scoring standard, including: assigning a structural stability score to each design scheme based on the evaluation results; assigning a construction feasibility score to each design scheme in combination with the structural stability score; calculating an overall score for each design scheme based on the feasibility score and taking into account cost-effectiveness factors; ranking all design schemes according to the overall score, and then selecting the design scheme with the highest ranking as the preferred scheme.

[0113] Assign a structural stability score to each design scheme: Based on the results of the ground stress distribution analysis and the safety assessment of the support structure, a structural stability score is assigned to each design scheme. The structural stability score can reflect the stability level of the design scheme under specific geological conditions. Generally speaking, the higher the score, the more stable the structure.

[0114] Assign a construction feasibility score to each design solution: Combined with the need for special treatment measures and the assessment results of construction risk points, a construction feasibility score is assigned to each design solution. The construction feasibility score reflects the feasibility and difficulty of the design solution in the actual construction process. A high score means that the construction is easier and more feasible.

[0115] Consider cost-effectiveness factors based on feasibility score: Combine the structural stability score with the construction feasibility score and consider the results of cost-effectiveness analysis to calculate an overall score for each design. The overall score should take into account safety, construction convenience, economic benefits and other factors.

[0116] Sort all design solutions by overall score: Sort all design solutions according to the overall score calculated above. The sorting results will help us quickly identify the best design solution.

[0117] Select the design scheme with the highest ranking as the preferred scheme: Select the design scheme with the highest score from the sorting results as the preferred scheme. The preferred scheme should be the one that performs best in terms of structural stability, construction feasibility, and economic benefits.

[0118] Furthermore, a detailed structural drawing is generated based on the preferred scheme, including: determining the design scheme with the highest score according to the sorting results, and formulating a detailed structural layout plan based on the determined design scheme; drawing the specific size and shape of each component according to the layout plan, and generating a complete and detailed structural drawing based on the specific size and shape.

[0119] Determine the design with the highest score: Based on the ranking results, identify the design with the highest score.

[0120] Based on the determined design plan, formulate a detailed structural layout plan: formulate a detailed structural layout plan, including the tunnel's direction, cross-sectional shape, support structure, drainage system and other key elements. The structural layout plan needs to fully consider geological conditions, construction technology and cost control and other factors.

[0121] Draw the specific size and shape of each component: Draw the specific size and shape of each component according to the layout plan, including but not limited to important components such as tunnel lining, support system, drainage facilities, etc.

[0122] Generate complete and detailed structural drawings: Use professional CAD software to draw complete structural drawings based on specific dimensions and shapes. The drawings should clearly indicate the location, dimensions, material specifications and construction details of each part.

[0123] Through this series of steps, it can be ensured that the final selected preferred solution not only excels in structural stability, construction feasibility and economic benefits, but also has detailed and accurate technical drawings, providing a solid foundation for subsequent construction implementation.

[0124] S4: Using the detailed structural diagram Dst, construct a three-dimensional digital model M3D of the preferred solution, and perform virtual construction simulation VS under various tunnel construction processes to identify corresponding potential construction difficulties Ni and risk points. By comparing and analyzing the construction difficulties and risk points corresponding to different processes, adjust the corresponding design details in the preferred solution to form an improved design solution Sopt′, M3D = build (Dstr) VS (M3D) → NiSopt′ = adjust (Sopt, Ni), where adjust is the process of constructing a three-dimensional model;

[0125] Furthermore, constructing the three-dimensional digital model of the preferred scheme includes: using the detailed structure diagram, starting the three-dimensional modeling software and creating a new project; in the created new project, importing the detailed structure diagram as a reference, and drawing the basic framework of the three-dimensional model according to the reference diagram; according to the basic framework, gradually adding details until the entire three-dimensional model is completed, and checking the consistency of the three-dimensional model with the detailed structure diagram.

[0126] Start the 3D modeling software and create a new project: Use professional 3D modeling software (such as AutoCAD, Revit, Navi sworks, etc.) to create a new project file according to project requirements.

[0127] Import detailed structural drawings as reference: Import detailed structural drawings into the 3D modeling software as reference drawings. These drawings contain detailed size and shape information of the tunnel and its ancillary structures.

[0128] 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 structure of the tunnel. You can start with simple geometric shapes and gradually refine them to more complex structures.

[0129] Gradually add details until the entire 3D model is completed: Based on the basic framework, gradually add more details, such as drainage system, ventilation system, lighting system, etc. Make sure that each part of the 3D model meets the requirements of the detailed structural drawing.

[0130] Check the consistency between the 3D model and the detailed structural drawing: Check whether the 3D model fully meets the design requirements in the detailed structural drawing. Verify whether the position, size and shape of each structural component are accurate.

[0131] Furthermore, potential construction difficulties are identified, including: based on the established three-dimensional digital model, starting a virtual construction simulation environment, setting a 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.

[0132] Start the virtual construction simulation environment: Start the virtual construction simulation function in the 3D modeling software or the dedicated construction simulation software. Set the parameters of the construction simulation, such as the construction sequence, construction machinery, and labor allocation.

[0133] Set construction sequence and schedule: According to the project plan, set a reasonable construction sequence and schedule. Consider the interdependencies between different construction stages.

[0134] Simulate the construction process: Simulate the entire construction process according to the set schedule. Observe each link in the construction simulation and pay attention to possible problems.

[0135] Record potential construction difficulties: Record any potential construction difficulties during the simulation. These difficulties may include space constraints, construction sequence conflicts, logistics issues, etc.

[0136] Specifically, based on the established 3D digital model, a virtual construction simulation environment is started. In this environment, the construction sequence and schedule are set to simulate the entire construction process. During the simulation, each construction stage will be advanced according to the set schedule. At this time, the observer needs to pay close attention to any problems that may arise during the simulation.

[0137] For example, when simulating the initial excavation stage, you may find the risk of rock collapse due to unstable geological conditions. Or when simulating the installation of the support structure, you may find that some heavy equipment cannot reach the designated location due to space limitations, thus affecting the construction progress. For another example, when simulating the installation of the drainage system, you may find that the originally designed drainage path does not match the actual geological structure, resulting in poor drainage and other problems.

[0138] The above observations need to be recorded in detail. The contents of the record should include the construction stage, specific location, expected problems, possible cause analysis, etc. Such records can help the design team understand the nature of potential difficulties and provide a basis for the next step of solution formulation.

[0139] After recording, 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 caused by unstable geological conditions, it may be necessary to strengthen the support structure or change the excavation method; if it is a space limitation issue, it may be necessary to re-plan the equipment transportation route or choose smaller but equally efficient equipment; for the problem of poor drainage, it is necessary to re-evaluate the drainage path and may need to adjust the design to ensure smooth water flow.

[0140] Through such steps, potential construction difficulties can be effectively identified and resolved, ensuring that the final design is both safe, reliable and cost-effective.
