%X Uniaxial compressive experiment of Nanjing sandstone and Dali marble is conducted on MTS with strain rate varied from 510- to 210-/s. It can be found that sandstone and marble are of obvious characteristics of anisotropy,but the anisotropy of marble is weaker than that of sandstone. And they are of obvious strain-rate effect,that is,strength increases with strain rate. Saturation liquid can promote the character of anisotropy and strain rate effect,and under the same strain rate,the viscosity of saturation liquid can only affect rock strength. As strain rate rises,the influence of viscosity on rock strength reduces.
