The invention relates to a basic internal friction angle measuring apparatus of a rock interface. The measuring apparatus comprises a case. One side of an operating console with a groove is hinged to the case; and the other side of the operating console cooperates with a lifting-up mechanism inside the case. One side of a sample clamping plate cooperating with a to-be-measured rock sample is connected with a groove inner wall by a spring in the groove. A baffle plate is arranged at the operating console and cooperates with the to-be-measured rock sample. A bar-shaped reflection piece is arranged at a base plate of the operating console; and a light source point cooperating with the bar-shaped reflection piece is arranged at the top surface of the operating console. A light sensing piece is arranged at the top end of the baffle plate; and a telescopic light source rod cooperating with the light sensing piece is installed at the operating console. According to the measuring apparatus, a problem of a large error of a dynamometer can be solved; and simple, convenient, and accurate indoor obtaining of a basic friction angle of a rock interface or a structural plane can be realized.
Description
Technical field [0001] The invention relates to the technical field of rock mechanics test equipment, in particular to a device for measuring the basic internal friction angle of a rock interface. Background technique [0002] In the fields of rock mechanics and engineering technology, the mechanical parameters of the friction angle between rock mass structural planes have always been the researcher's focus. [0003] At present, there are two main methods for obtaining the basic friction angle of rock mass surface and structural surface. One is to directly lift two approximately flat rocks by hand for tilt test, and then roughly visually obtain the basic friction angle. , Usually the result is large and not accurate enough. Another method is to place the rock sample on a standard horizontal surface, measure the quality of the rock sample first, use a tension meter to pull the rock sample horizontally, and record the tensile force at that time when the rock sample starts to move.
