摘　　要：以弹性力学理论和地震波在岩体介质中的传播规律为基础,从理论上推算了结构面上的反、透射系数,讨论了入射角、波阻抗等对反透射系数的影响;依据摩尔库仑准则,得出一定条件下的边坡稳定的入射角范围;同时,从理论上说明爆破工程中采用质点振速为依据判断爆破地震效应是在理论上是合理的。based on the theory of elastic mechanics and the principles of earthquake wave propagating in the rock medium, this paper calculates theoretically the reflective transmission coefficient in the structural planes, and discusses the influences of the angle of incidence and wave impedance on the reflective transmission coefficient. The scope of the angle of incidence about slope stability is reckoned under some certain conditions based on the maxim of Coulomb-Mohr; Also, this paper proves theoretically that applying particle＇s vibration velocity to estimate the effect of blasting vibration in the blasting project is reasonable in the theory.
