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

Abstract

The invention discloses a tunnel dangerous stone displacement real-time monitoring system and method considering the rotation effect, and the system comprises a rigid support, a tilt angle measuring mechanism, a laser target mechanism, a laser launching mechanism and a displacement segment identification system, a rigid support and a dangerous stone. Connecting, the rigid bracket is fixed with a tilt angle measuring mechanism for measuring the tilt angle thereof and a laser emitting mechanism for emitting the laser light source, and the laser light source is irradiated to the laser target mechanism disposed outside the rigid bracket, and the displacement segment is discriminated The system collects the tilt angle, the laser source illumination distance, and the offset of the laser target to determine the rotational displacement and rigid displacement of the dangerous stone. The invention can accurately obtain the rotation angle and the displacement change data of the dangerous stone while considering the rotation effect of the dangerous stone, and can not only reduce the interference to the tunnel construction, but also realize the segmentation identification of the dangerous stone rotation angle and the rigid translation to ensure the segmentation of the critical stone rotation angle and the rigid translation. Tunnel construction is safe.

Description

technical field [0001] The invention relates to a real-time monitoring system and method for the displacement of dangerous rock in a tunnel considering the rotation effect. Background technique [0002] In the process of tunnel construction, a large number of discontinuities are encountered, such as faults, bedding, joints, etc., so the basic characteristics of the tunnel rock mass are discontinuous, non-uniform and non-isotropic, and the intersection and combination of discontinuities will lead to dangerous. Stone falls. The displacement monitoring of dangerous rock is an important basis for judging its 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 shortcomings: [0004] (1) Real-time monitoring is not possible, that is, the displacement changes of dangerous rocks cannot be reflected in real time; [...
