Description

Technical Field

[0001] The invention belongs to the technical field of tunnel engineering, and in particular relates to a tunnel dynamic feedback system in an earthquake-prone area based on real-time monitoring. Background Art

[0002] In earthquake-prone areas, tunnel construction faces complex geological conditions and extremely high engineering risks. Due to earthquake action and surrounding rock instability, problems such as surrounding rock deformation, vault settlement, water and mud inrush, and rock bursts often occur during tunnel construction, posing a threat to construction safety and the stability of the support structure.

[0003] Traditional tunnel construction support design relies on static geological analysis and construction experience, and it is difficult to respond to the surrounding rock changes and earthquake dynamic impacts that occur during the construction process. Especially when an earthquake occurs, the mechanical properties of the surrounding rock change rapidly, and the traditional support design and adjustment methods lag behind, which can easily cause tunnel collapse and support failure.

[0004] In recent years, the application of real-time monitoring technology has made dynamic feedback and optimization possible during the construction process. 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 the construction process. In addition, the optimization strategy for tunnel support design in earthquake-prone areas has not yet formed a standardized process, which affects 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 parameters, surrounding rock mechanics monitoring data, and construction process data to form a closed-loop monitoring, analysis, feedback, and optimization mechanism, dynamically adjust the construction support plan, and improve the safety and efficiency of tunnel construction in earthquake-prone areas. Summary of the invention

[0006] In order to solve the problems mentioned in the background technology, the present invention provides a dynamic feedback system for tunnels in earthquake-prone areas based on real-time monitoring. The system can collect a variety of monitoring data in real time during the construction process, and generate support optimization plans 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 tunnel dynamic feedback system for earthquake-prone areas based on real-time monitoring is provided, including but not limited to the following modules:

[0008] Monitoring module, used to collect surrounding rock deformation, vault settlement, perimeter convergence, seismic vibration acceleration, and groundwater inflow during tunnel construction;

[0009] The data processing module is used to integrate and analyze the data collected by the monitoring module from multiple sources to generate surrounding rock stability predictions and support optimization suggestions;

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

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

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

[0024] In rock burst areas, optimize the layout of energy-absorbing anchors;

[0025] In the water-gushing and mud-bursting section, adjust the waterproof layer structure and the layout of the drainage system;

[0026] In earthquake impact areas, optimize the spacing between steel arches and the thickness of shotcrete.

[0027] The feedback module needs to combine the preset support optimization rules, anchor density, steel arch spacing and shotcrete thickness to generate a dynamic support optimization plan, dynamically adjust the anchor arrangement method of the soft surrounding rock and rock burst section, optimize the distribution density of the energy-absorbing anchor, optimize the shotcrete thickness and steel arch arrangement spacing for the high-impact earthquake area, ensure the seismic performance of the support structure, optimize the drainage design in the water-rich section through dynamic drainage measures, and send this to the execution module.

[0028] In some embodiments, as a further preferred solution, the execution module includes automated construction equipment for executing anchor arrangement, concrete spraying and steel arch installation according to the support optimization solution provided by the feedback module. Short footage and weak blasting technology are used in the through section and karst zone, and the construction rhythm and support strength are adjusted in combination with real-time monitoring. Afterwards, the construction execution status needs to be fed back to the data processing module in real time for further analysis and optimization.

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

[0030] The monitoring module collects data on the vault settlement, perimeter convergence, surrounding rock stress, earthquake vibration acceleration, and groundwater inflow during tunnel construction;

[0031] In the data processing module, multi-source fusion and trend analysis are performed on the monitoring data to predict the stability and deformation trend of the surrounding rock;

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

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

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

[0036] In some embodiments, as a further preferred solution, the support optimization solution generated by the feedback module is updated according to real-time data, including:

[0037] Adjustment of anchor density;

[0038] Optimization of steel arch spacing;

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

It can analyze data and generate support optimization suggestions in a short time, realize rapid processing and feedback of construction dynamic data, and significantly improve the construction response speed. The multi-source data fusion algorithm and trend prediction model are used to analyze and predict the monitoring data, and generate surrounding rock stability assessment results and construction optimization plans. The automated analysis and feedback of data greatly reduces manual intervention and improves decision-making efficiency and accuracy.

[0042] Moreover, through the surrounding rock stability prediction model and the early warning mechanism of high-risk areas, the system can timely identify potential risks such as rock bursts, water inrush or earthquake shocks.
