Rock triaxial test is an important means to study rock mechanics, and rock triaxial test data is an important parameter of rock mechanics. It can completely simulate the mechanical properties of rock and soil under the original geostress state, and is an important basis for engineering design. Because the deep rock is in a complex stress state, the rock mass or ore body encountered in mining engineering is mostly in a three-dimensional stress state, and is itself a very complex natural material. In many cases, the rock stress test under simple stress state cannot * reflect the rock mass stress state in engineering practice, and the mechanical properties of rock under complex stress state must be fully understood.
Therefore, it is very important to carry out rock test research under triaxial condition. Rock triaxial testing machine is the basic testing equipment for studying rock mechanical properties. According to the rock testing regulations and the characteristics of the current engineering construction, a high-performance rock triaxial testing machine has been developed by refitting the existing pressure testing machine. It can be applied to the triaxial shear test of rock under high confining pressure and the triaxial creep test of rock under constant confining pressure. The test parameters can be set according to the requirements. The whole test process is controlled by a computer and the test data is automatically recorded. It is a relatively economic and practical rock triaxial test equipment with a high degree of automation.
