Abstract

The invention discloses a device for testing a basic friction angle of a rock joint under real-time high temperature conditions. The device comprises a heating box, a frame, a reversing gear set and amotor. The heating box is formed from a bottom plate, a top plate and side plates. One side of the bottom plate is arranged above the frame and the other side of the bottom plate is hinged to the frame. An axle is arranged in the middle of the bottom of the bottom plate. An input end of the reversing gear set is connected to the motor. An output end of the reversing gear set is connected to the axle. The device can test the basic friction angle of a rock joint in a real-time high temperature environment. The heating rate and temperature in the high temperature environment can be set accordingto demands. The device is suitable for study in various temperature environments. The tilt rate and the tilt angle can be set according to demands. The device has a wide application range and produces research results with high feasibility.

Description

technical field [0001] The invention relates to the technical field of rock mechanics and engineering, in particular to a device and method for testing the basic friction angle of rock joints under real-time high temperature conditions. Background technique [0002] In recent years, human engineering activities have gradually moved towards deep rock masses, such as geological disposal of high-level radioactive waste, and underground caverns for compressed air energy storage. In such deep rock mass engineering construction, temperature is one of the important factors affecting the properties of rock joints. The basic friction angle, as a basic parameter for estimating the peak shear strength of rock joints, has attracted the attention of many scholars at home and abroad in recent years, but the current results are all obtained by testing at room temperature. There is no report on the research results of the basic friction angle test of rock joints under the action of real-ti...
