Abstract

The transparent tri-axial compression servo-control test system is introduced. It is composed of axial pressure loading system，confining pressure loading system，transparent tri-axial compression chamber，loading controlled system，data acquisition system，image acquisition system et al. The maximum axial load is 500 kN；and the maximum confining pressure is 10 MPa，and the dimensions of test cylinder samples are Φ25 mm×50 mm. There are several advantages of this system：(1) A wide loading rate can be realized for investigate loading rate dependency of rock. (2) Many kinds of load forms can be completed on this servo-controlled system，cooling system is cancelled after hydraulic source modified. (3) A warning trigger is designed for enhance safety during test. (4) A image acquisition system is designed for measure deformation of specimen and the influence of end-effect can be eliminate with this method. (5) Based on the images, the evolution of crack can be observed and described in three-dimensional stresses.

Key words： rock mechanics transparent triaxial compression digital image processing crack evolution
