Problems solved by technology

The construction and operation stages of the tunnel structure are often monitored manually. It is difficult to detect and predict the surface settlement and structural deformation process caused by the tunnel construction at the fault in time. As a result, the imminent structural damage cannot be reinforced in time. Traditional monitoring and early warning often Single, unable to monitor and warn the whole life cycle of the tunnel structure systematically

Abstract

The invention relates to a method for monitoring and early warning of the whole life of a tunnel structure at a fault, belonging to the field of tunnel monitoring. The system includes a sensor, a monitoring center platform, data storage and an alarm; the sensor is connected to the monitoring center platform; the monitoring center platform is respectively connected to the data storage and the alarm; the limit value of the monitoring index is obtained by numerical limit analysis; Then analyze the numerical simulation results of the tunnel section at the fault; by comparing the numerical values ​​of the obtained results, the position and arrangement of the monitoring points at the variable section section can be obtained; according to the force distribution law of the tunnel structure at the fault, the stability evaluation standard of the tunnel structure is drawn up, Establish the monitoring and control indicators of the tunnel structure at the fault, including: the monitoring index of the formation deformation and the deformation and stress monitoring index of the tunnel structure at the fault.

Description

technical field [0001] The invention belongs to the field of tunnel monitoring and relates to a method for monitoring and early warning of the whole life of a tunnel structure at a fault. Background technique [0002] A fault is a structure in which the crust is fractured by force, and the rock blocks on both sides of the fracture surface undergo significant relative displacement. The construction of tunnels in mountainous areas may cross fault structures. Due to tectonic movements, faults develop structural shapes of different sizes and scales, but they all destroy the continuity and integrity of rock formations. Rocks on fault zones are often broken and easily weathered erosion. When the tunnel passes through the fault, the surrounding rock is broken, the stability is poor, the friction of the surrounding rock at the fault is reduced, the deformation and force of the surrounding rock are large, and accidents such as collapse and block falling are prone to occur, and the s...
