Problems solved by technology
[0003] At present, the monitoring methods for specific dangerous rocks are relatively simple, and the traditional displacement monitoring and measurement methods have the following deficiencies:
[0004] (1) It cannot be monitored in real time, that is, it cannot reflect the displacement changes of dangerous rocks in real time;
[0005] (2) The construction disturbance is large, that is, the erection of monitoring instruments seriously interferes with the tunnel transportation operation;
[0006] (3) The rotation effect of the rock is not considered, and the displacement of the dangerous rock includes the vector sum of the displacement generated by the rotation and the rigid translation

The invention discloses a system and method for monitoring tunnel dangerous rock displacement based on rotation effects. The system comprises a rigid support, a dip angle measuring mechanism, a laser targeting mechanism, a laser emitting mechanism and a displacement segmented identification system. The rigid support is connected to a dangerous rock. The dip angle measuring mechanism for measuring a dip angle and the laser emitting mechanism for emitting a laser resource are fixed to the rigid support. The laser resource irradiates the laser targeting mechanism outside the rigid support. The displacement segmented identification system acquires a dip angle, a laser resource irradiation distance and an offset of a laser target and ensures the rotational displacement and rigid displacement of the dangerous rock. The system and method can accurately acquire the dangerous rock rotation angle and displacement change data based on the dangerous rock rotation effects, reduce interference to the tunnel construction, realize segmented identification of the rotation angle and rigid translation of the dangerous rock and guarantee tunnel construction safety.
Description
technical field [0001] The invention relates to a real-time monitoring system and method for the displacement of dangerous rocks in tunnels considering the rotation effect. Background technique [0002] In the process of tunnel construction, a large number of discontinuities, such as faults, beddings, joints, etc., are encountered, which form the basic characteristics of discontinuous, non-uniform, and non-isotropic rock mass in the tunnel. The intersection and combination of discontinuities will lead to dangerous The stone fell. Displacement monitoring of dangerous rocks is an important basis for judging their stability and guiding construction. [0003] At present, the monitoring methods for specific dangerous rocks are relatively simple, and the traditional displacement monitoring and measurement methods have the following deficiencies: [0004] (1) It cannot be monitored in real time, that is, it cannot reflect the displacement changes of dangerous rocks in real time; ...
