AI Technical Summary

Technical Problem

Existing early warning systems for underground tunnel construction lack the ability to dynamically adapt to the characteristics of strata-layered settlement and the evolution of disturbance zones, resulting in a low degree of matching between early warning signals and actual risks. The adjustment of the support system and the optimization of the construction rhythm rely on preset parameters and do not combine real-time sensing data and simulation prediction values ​​for closed-loop feedback. Furthermore, there is a lack of a collaborative optimization strategy for multi-level interlocking support structures and flexible adjustment devices, which leads to insufficient deformation resistance of the support system and is prone to local instability risks.

Method used

A multi-module collaborative system is constructed, including a real-time perception module, a risk identification and early warning module, and a support intervention execution module. By deploying multiple types of sensors at key nodes of the support system, and combining simulation analysis results with multi-objective optimization algorithms, the system can continuously collect structural mechanical parameters and stratum deformation data, dynamically adjust early warning thresholds and support system configurations, optimize construction sequence and pace, and form a closed-loop control.

Benefits of technology

It enables real-time control of surrounding rock deformation and the stress state of the support structure, improves construction safety and stability, significantly reduces false alarm and false alarm rates, optimizes the response strategy of the support system, and enhances risk control capabilities during construction.

Abstract

The invention relates to an underground excavation tunnel construction early warning system, which belongs to the technical field of tunnel construction early warning, and comprises a real-time sensing module capable of deploying multiple types of sensing devices at key nodes of a support system and continuously collecting structural mechanical parameters and stratum deformation data; the risk identification and early warning module can dynamically compare the real-time sensing data with a simulation prediction value, identify an abnormal disturbance area, adjust an early warning threshold according to stratigraphic settlement characteristics and a disturbance partition evolution law, and trigger a graded early warning signal; the support intervention execution module can dynamically adjust the configuration and construction rhythm of a support system according to the early warning signal and the structure stress map, and the real-time sensing module can arrange a sensing device on the support system in the section where pilot tunnel construction is conducted according to the optimal construction sequence. And the optimal construction sequence and the supporting system arrangement mode can be screened and determined by adopting a multi-objective optimization algorithm based on a simulation analysis result.
