Abstract

The invention discloses a surrounding rock-arch frame contact relationship monitoring device and a use method thereof. The device is composed of a surrounding rock, an arch frame, a force monitoring module and a displacement monitoring module. The force monitoring module is composed of a short anchor rod, a carrier plate, a nut and a pressure box. The displacement monitoring module is composed oftwo wire-type displacement sensors and a positioning hole. According to the invention, the pressure box is arranged to monitor the surrounding rock pressure; by monitoring the data of the displacementsensors before and after deformation, radial relative displacement and circumferential relative displacement are calculated, and thus relative deformation state between the arch frame and the surrounding rock is quantified; and the device can monitor the pressure of the surrounding rock at any position of the arch frame and can monitor the relative displacement of the surrounding rock and the arch frame.

Description

technical field [0001] The invention relates to the technical field of underground engineering (roadway, tunnel) monitoring, in particular to a surrounding rock-arch contact relationship monitoring device and a use method. Background technique [0002] In recent years, arches (steel arches, grid arches, steel pipe concrete arches, etc.) have been widely used as a high-strength support technology in roadways, tunnels and other underground projects, and achieved good results. The contact relationship between the surrounding rock and the arch determines the stress state of the arch, which in turn affects the bearing capacity of the arch. When the contact relationship between the surrounding rock and the arch frame is poor, the arch frame is prone to local instability and damage, and the overall bearing capacity of the arch frame is difficult to fully exert; and the good contact relationship between the surrounding rock and the arch frame can prevent the arch frame from being su...
