The phenomenon of the rock damage and fracture by shock wave of exploding in fractures was simulated via the experiment of exploding on the surface of the cement sample in deep water.The peak pressure decline of shock wave,which was suitable for this experiment,was obtained pm≈8.2W~1/3/R1.46.Results indicate that the crushed zone and tensile damage zone dimensions are about 2~5,20~30 times of the powder characteristic dimension respectively.Approximate energy consumed by shock wave to generate crushed and fracture zone in cement sample is 2%~7% of the total energy.
