Abstract

The invention discloses a non-contact real-time monitoring system and method for surrounding rock and face deformation in model tests, comprising: a laser emitting device is fixed on a balance support through a support, and the laser emitting device and a data transmission module are respectively connected to a power supply module The laser emitting device includes a laser emitting device body and an internal data acquisition module, a front laser cannon and a rear laser cannon are respectively arranged on the front and rear two end faces of the laser emitting device body, and several Circumferential laser cannon. Beneficial effects of the present invention: through the angle-adjustable laser emitting device and the circular laser cannon, the problem of simply using multiple monitoring elements embedded in the model and the survival rate of the elements cannot be guaranteed is overcome, and the simulation effect of a large number of embedded monitoring elements is also reduced It also solves the problem of real-time monitoring of multiple cross-sections at all angles.

Description

technical field [0001] The invention relates to a non-contact real-time monitoring system and method for the deformation of surrounding rock and face in a model test. Background technique [0002] With the rapid development of the domestic economy in recent years, the development of underground projects has sprung up like mushrooms, especially in the central and western regions where the terrain, landform and geological background are complex, water energy and mineral resources are abundant, and the density of land transportation networks is far lower than the national average. With the acceleration of the development process in the central and western regions of my country, the development and utilization of railways, highways, hydropower, inter-basin water transfer and mineral resources involving complex strata and deep underground space are ready to go. The development and utilization of deep underground spaces and complex formations has driven scientific and technological...
