Dynamic triaxial compressive test for a granite were conducted with strain rates 10-4-ls-1 and confining pressure 20-170 MPa. The results show that the compressive strength of the granite increases with the increasing of the strain rate, and the increment of the rates decreases with the increasing of the confining pressure. The results also show that the Young's modulus and Poisson's ratio have no clear connection with the strain rate. The compressive strength increases with the increment of the confining pressure significantly, and the tendency are almost independent of the strain rates. In addition, the Young's modulus increases and Poisson's ratio decreases slightly with the increasing of the confining pressure for all applied strain rates.
