Abstract
A rock mechanics triaxial testing machine includes an outer pressure chamber and an inner pressure chamber located inside the outer pressure chamber, and a side wall of the inner pressure chamber is provided with a communication hole communicating with the outer pressure chamber; an upper pressure head and a lower pressure head which may be placed inside the inner pressure chamber; an axial pressure driving member, the axial pressure driving member may drive the upper pressure head and lower pressure head to approach each other to squeeze the rock sample; an axial deformation sensor, a radial deformation sensor, a lifting mechanism, the lifting mechanism may drive the inner pressure chamber to rise and fall. In the rock mechanics triaxial testing machine, the inner pressure chamber and the outer pressure chamber are nested indoors and outdoors, and the inner pressure chamber is used to quickly mount rock test samples.
