Abstract

The invention provides a leveling device for a rock direct shear friction experiment. The leveling device comprises a ball head, a ball seat and an abutting part, wherein the ball seat can be fixed on an experiment table board, the top of the ball seat is provided with a recessed cavity matched with the shape of the ball head, the ball head is located in the recessed cavity, and a platform for fixing a to-be-tested rock sample is connected to the top of the ball head; the ball head can rotate in the recessed cavity and drive the platform to move to allow the friction face of the to-be-tested rock sample on the platform to be located at a preset position; the abutting part can be abutted against the ball head, and the ball head and the ball seat keep relatively still under the friction force of the abutting part when the abutting part is abutted against the ball head. The leveling device has the advantages that the position of the platform is adjusted through the rotation of the ball head until the to-be-tested rock sample on the platform is in face-face contact with a rock sample above the to-be-tested rock sample, and friction experiment precision is guaranteed.

Description

technical field [0001] The invention relates to the technical field of equipment for rock friction experiments, in particular to a leveling device for rock direct shear friction experiments. Background technique [0002] The rock direct shear friction experiment is the most direct experimental method for simulating the frictional sliding of faults. It is an important means to evaluate and study the sliding behavior and mechanical properties of faults, and it is of great significance in the study of the mechanism of earthquake formation. [0003] When performing the rock direct shear friction test, two rock samples to be tested are clamped separately, and then the two rock samples to be tested are placed opposite each other up and down. The opposite surface of the two rock samples to be tested is the friction surface, so that the friction experiment. The prior art usually uses a shear box to clamp the rock sample to be tested, that is, two rock samples to be tested are respe...
