The invention provides a rock double-sided shear test device and a test method, and relates to the field of rock tests. The test device comprises a main frame, a base, a shearing tool, a tangential loading mechanism, a first normal loading mechanism, a second normal loading mechanism and a control system, the base is arranged on the inner side of the main frame, and the shearing tool is installed on the base; the tangential loading mechanism and the shearing tool are oppositely arranged, the tangential loading mechanism is provided with a tangential pressure head, and the tangential pressure head is matched with the tangential positioning part of the shearing tool so as to apply opposite tangential loads to the rock sample; the first normal loading mechanism and the second normal loading mechanism are located on the opposite sides of the shearing tool. The two normal loading mechanisms are provided with normal pressure heads, and the two normal pressure heads are used for applying opposite normal loads to the rock sample; the control system is electrically connected with the tangential loading mechanism, the first normal loading mechanism and the second normal loading mechanism so as to control the two normal loading mechanisms to generate mutually independent load forms.
Description
technical field [0001] The invention relates to the technical field of rock tests, in particular to a rock double-sided shear test device and a test method. Background technique [0002] Underground faults may cause earthquakes when they are disturbed. It is of great significance to study the slip law and mechanical properties of rock faults for the study of geological disasters such as earthquakes. Because the stress forms of the fault are various, the conventional single-sided shear test cannot accurately reflect the stress state of the rock. [0003] Subsequently, a Chinese utility model patent with the authorization announcement number CN203758856U and the authorization announcement date of 2014.08.06 disclosed a bidirectional shear test device for rock structure planes, which specifically includes a test piece, a pressing plate device, a roller set device, a loading device, Data acquisition device and base; the specimen is the upper and lower rock blocks bounded by the...
