摘要(Abstract)：
分别对不同类型裂隙与应力波的相互作用进行讨论．由于裂隙的存在，使应力波在裂隙岩体中和均匀岩体中的衰减机理不同，应力波的破碎范围减小，但局部过度破碎、块度不均．
In this paper, the redaction of different kinds of craCks and stress wave are discussed. And the following condition is drawn f due to the existenCe of crack, the attenuationmeChanism of streSS wave in crack rock mass is different from that in the even material rockmass, the flaglnentation range of stress wave decreases, but the local rock is excessively damagedand the fragment distribution is not even.
