Abstract

The invention relates to the field of testing equipment of rock mechanics and provides a rock shear test system. According to the rock shear test system, the problems that the internal deformation mechanism and structural evolution of rocks in the shear breakage process cannot be known in the prior art are solved. The rock shear test system comprises a loading device and a driving device, whereinthe loading device comprises a loading bin which is configured to apply a shear force to a rock test piece; and the driving device is connected with the loading bin and is used for driving the loadingdevice to drive the rock test piece to rotate. According to the rock shear test system, the functions of a rock shear test machine are realized, the internal deformation mechanism and structural evolution of the rocks in the shear breakage process can be acquired through lossless CT scanning, the rock shear breakage process can be dynamically observed, and the reference basis is provided for solving the rock engineering problems in construction projects of hydraulic engineering and buildings.

Description

technical field [0001] The invention relates to the field of rock mechanics test equipment, in particular to a rock shear test system. Background technique [0002] The research purpose of rock mechanics is to solve rock engineering problems in water conservancy, civil engineering and other construction projects. In order to obtain the stress-strain data of rocks under shear failure and to further understand the internal structure of rocks, some scholars began to study rocks with the help of industrial CT (Computed Tomography, electronic computer tomography) technology. [0003] In the prior art, to detect the internal structure of the rock, the rock needs to be placed on the turntable of the CT system, and the rock is scanned by high-energy rays. This method can only obtain the complete internal structure of the rock specimen. If you want to understand the The rock structure needs to be subjected to a compression-shear test with a rock shear testing machine in advance to o...
