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 propagation of seismic waves in rock mass media, the anti-reflection coefficient and transmission coefficient on the structural plane are deduced theoretically. The influences of incident angle and wave impedance on the anti-reflection coefficient are discussed. According to the Mohr-Coulomb criterion , The stable incident angle range of the slope under certain conditions is obtained. At the same time, it is theoretically reasonable to judge the blasting seismic effect based on the particle velocity in blasting engineering theoretically.
