| Abstract: | This paper introduces the structural characters and functions of the rock high pressure true triaxial machine newly developed and some research results with this machine. By the rock high pressure true triaxial machine, three principal stresses can be controlled and changed independently, so that any stress state and stress path in engineering rock mass and earth’s crust can be simulated. It is an important development of Karman type general triaxial machine.
By RT3 type rock high pressure true triaxial machine, the maximum principal stress can be applied up to 800 MPa, the intermediate and minimum principal stress up to 200 MPa. The strains and parameters of sonic wave in the directions of three principal stresses can also be determined. The machine is used well for studying the basic theory on rock mechanics, the stability of engineering rock mass and the behaviors of earthquake precursors. |
