摘要：采用 ANSYS/LS-DYNA软件对冲击波在水、土、混凝土中的衰减规律进行了模拟研究，由计算得到的压力和能量的曲线，通过分析表明波阻抗对冲击波的初始峰值大小有很大的影响；土中冲击波的持续时间最长，混凝土中冲击波衰减较快；验证了冲击波速和波强度有关，波的强度越大，波速越高；能量的大小和介质的可压缩性有关，土中能量最大，水中能量最小。

Abstract: The attenuation law of shock wave in water, soil and concrete were numerically simulated by applying ANSYS/LS-DYNA. The results showed that: The magnitude of wave impedance has greater effects of the shock wave initial peak; the shock wave in soil lasted the longest and decay slower. The relationship between the shock wave speed and intensity is approved, the greater intensity, the higher velocity. The media compressibility has greater effects of the energy. The energy in soil is maximal, which in water is minimum.
