摘    要：为考察不同形式的应力波通过夹层等岩体结构时的传输效应和能量传递效果,本文给出了一种求解应力波在层状矿岩结构中传播效应的新算法——等效波阻法。使用这种方法即可很容易地求算不同加载波形和不同矿岩结构条件下的透射效应和能量传递效果。

Abstract: In order to investigate the propagating characteristics of stress waves and their energytransmission effects through some rock structures, such as layered and sandwich rockmassesthis paper presents a new computation method: the effective acoustic impedance method. Bymeans of this method, the forms of the transmitted waves generated by incident transientwaves with different waveforms through sandwichs with different acoustic impedances andthe corresponding energy transmission effects can easily be obtained.
