Description

Technical Field

[0001] This invention belongs to the field of tunnel engineering technology, and in particular relates to a dynamic feedback system for tunnels in earthquake-prone areas based on real-time monitoring. Background Technology

[0002] In earthquake-prone areas, tunnel construction faces complex geological conditions and extremely high engineering risks. Due to seismic forces and the instability of the surrounding rock, problems such as surrounding rock deformation, arch settlement, water and mud inrush, and rock bursts frequently occur during tunnel construction, threatening construction safety and the stability of the support structure.

[0003] Traditional tunnel support design relies on static geological analysis and construction experience, making it difficult to respond promptly to changes in the surrounding rock and dynamic impacts of earthquakes during construction. Especially during earthquakes, the mechanical properties of the surrounding rock change rapidly, and traditional support design and adjustment methods lag behind, easily leading to tunnel collapse and support failure.

[0004] In recent years, the application of real-time monitoring technology has made dynamic feedback and optimization during the construction process possible. However, existing monitoring systems often only target a single data source (such as displacement, stress, or seismic vibration) and lack the dynamic analysis function of multi-parameter fusion, making it difficult to achieve automatic feedback and optimization during construction. In addition, optimization strategies for tunnel support design in earthquake-prone areas have not yet formed a standardized process, affecting the safety and efficiency of construction.

[0005] Therefore, there is an urgent need for a dynamic feedback system based on real-time monitoring that can integrate seismic motion parameters, surrounding rock mechanics monitoring data, and construction process data to form a closed-loop monitoring, analysis, feedback, and optimization mechanism, dynamically adjust construction support schemes, and improve the safety and efficiency of tunnel construction in earthquake-prone areas. Summary of the Invention

[0006] To address the problems mentioned in the background art, this invention provides a dynamic feedback system for tunnels in earthquake-prone areas based on real-time monitoring. This system can collect various monitoring data during construction in real time and generate support optimization schemes through data fusion and feedback algorithms, thereby realizing dynamic adjustment of support design and improving construction safety and adaptability.

[0007] Based on the first main aspect of the present invention, a dynamic feedback system for tunnels in earthquake-prone areas based on real-time monitoring is provided, including but not limited to the following modules:

[0008] The monitoring module is used to collect data on surrounding rock deformation, arch settlement, perimeter convergence, seismic vibration acceleration, and groundwater inflow during tunnel construction.

[0009] The data processing module is used to perform multi-source fusion and analysis on the data collected by the monitoring module to generate surrounding rock stability predictions and support optimization suggestions;

[0010] The feedback module generates a real-time construction support optimization plan based on the analysis results of the data processing module. The plan includes adjusting the anchor bolt density, shotcrete thickness, and steel arch spacing.

[0011] The execution module is used to transmit the optimized solutions generated by the feedback module to the construction site and execute them, including the dynamic adjustment of support parameters and the optimization of construction technology.

[0022] The algorithm integrates, analyzes, and predicts multi-source data collected by the monitoring module to generate surrounding rock stability assessments and construction support optimization suggestions.

[0023] In some embodiments, as a further preferred embodiment, the feedback module generates a construction support scheme based on preset optimization rules, including:

[0024] In rockburst areas, optimize the arrangement of energy-absorbing anchor bolts;

[0025] For sections with water inrush and mud leakage, adjust the structure of the waterproof layer and the layout of the drainage system;

[0026] In earthquake-affected areas, optimize the spacing of steel arch frames and the thickness of shotcrete.

[0027] The feedback module needs to combine preset support optimization rules, anchor density, steel arch spacing and shotcrete thickness to generate a dynamic support optimization scheme, dynamically adjust the anchor arrangement in weak surrounding rock and rockburst sections, optimize the distribution density of energy-absorbing anchors, optimize the shotcrete thickness and steel arch spacing in high-impact earthquake zones to ensure the seismic performance of the support structure, optimize the waterproofing and drainage design in water-rich sections through dynamic drainage measures, and send this to the execution module.

[0028] In some embodiments, as a further preferred option, the execution module includes automated construction equipment for performing anchor bolt placement, shotcreting, and steel arch installation based on the support optimization scheme provided by the feedback module. Short-cut, low-explosion techniques are used in the through section and karst zone, combined with real-time monitoring to adjust the construction pace and support strength. Subsequently, the construction execution status needs to be transmitted back to the data processing module in real time for further analysis and optimization.

[0029] Based on the second main objective of this invention, a dynamic feedback method for tunnels in earthquake-prone areas based on real-time monitoring is provided, comprising the following steps:

[0030] The monitoring module collects data on crown settlement, perimeter convergence, surrounding rock stress, seismic vibration acceleration, and groundwater inflow during tunnel construction.

[0031] In the data processing module, the monitoring data is fused from multiple sources and trend analyzed to predict the stability and deformation trend of the surrounding rock.

[0032] In the feedback module, a dynamic support optimization scheme is generated based on the analysis results, including adjustment of support materials and optimization of construction parameters;

[0033] In the execution module, the support measures are dynamically adjusted according to the optimization plan, including anchor bolt density, steel arch spacing and concrete spraying thickness. The support optimization is implemented through automated construction equipment, and the execution data is sent back to the data processing module for verification in real time.

[0034] In some embodiments, as a further preferred option, the monitoring frequency of the monitoring module can be dynamically adjusted to achieve high-frequency monitoring for high-risk areas, ensuring timely response to abnormal changes.

[0035] In some embodiments, as a further preferred embodiment, the data processing module generates a surrounding rock stability level and issues an early warning signal for high-risk areas based on historical data and real-time monitoring data. The intelligent processing of tunnel construction data reduces manual intervention and improves decision-making efficiency and accuracy.

[0036] In some embodiments, as a further preferred embodiment, the support optimization scheme generated by the feedback module is updated based on real-time data, including:

[0037] Adjustment of anchor bolt density;

[0038] Optimization of steel arch frame spacing;

[0039] The thickness of the sprayed concrete is dynamically adjusted, and the optimization scheme is continuously updated through real-time data.

[0040] Advantages and beneficial effects of the present invention:

[0041] This invention, through a real-time monitoring module and a wireless communication module, can collect data such as surrounding rock deformation, arch settlement, perimeter convergence, and seismic vibration parameters in real time during tunnel construction and rapidly transmit them to a data processing module. It can analyze the data and generate support optimization suggestions in a short time, achieving rapid processing and feedback of dynamic construction data, significantly improving construction response speed. Employing multi-source data fusion algorithms and trend prediction models, it analyzes and predicts monitoring data to generate surrounding rock stability assessment results and construction optimization schemes. Automated data analysis and feedback greatly reduce manual intervention, improving decision-making efficiency and accuracy.

[0042] Furthermore, through the surrounding rock stability prediction model and the early warning mechanism for high-risk areas, the system can promptly identify potential risks such as rock bursts, water inrushes, or seismic impacts. Support measures at the construction site can be dynamically adjusted based on real-time feedback from the module, effectively reducing potential safety hazards during tunnel construction.
