Abstract: Artificial joints were used for direct shear tests under four levels of normal stresses, i. e. 0.5,1.0, 2.0 and 3.0 MPa,to simulate the effect of shear deformation history. The results showed that peak strength decreased with the shear times increasing. In addition, the discrepancy between the result of direct shear test for the first time and for the second time was the most obvious. With shear times increasing, there were fewer changes of peak shear strength in following tests. Analyzing dilatancy characteristics and changes of peak shear strength under normal stresses, the peak shear strength criterion considering the effect of shear deformation history was established.

Key words: rock joint, peak shear strength, shear history
