%X Shock compression SHPB (split Hopkinson pressure bar) tests were carried out for dry, saturated with water and saturated with pumping oil marble and saturated sandstone, respectively, and stress wave attenuation rules of dry and saturated rock were obtained. During the stress wave propagation process, its amplitude attenuation is obvious; the attenuation of dry rock is the largest. The rocks with greater porosity have more obvious attenuation. Saturated rocks have rather intensive wave dispersion effect. When impact loading is smaller than rock yield strength, the results of multi-impact loading show that loading modulus increases and residual strain reduces along with the increase of impact loading number. These results can be used for the design and construction of large-scale earthquake engineering and protection engineering.
