摘要

摘要: 研究平稳随机波在粘弹性分层横观各向同性介质中的传播问题．将岩层考虑为分层介质，各层性质不同，岩层位于基岩上面，并且认为基岩比岩层刚很多，在基岩处给出随机激励．在频率和波数域中将控制方程化为常微分方程求解．对常微分方程，应用两点边值问题的精细积分法进行求解．因此，近年来发展的应用于结构随机振动的虚拟激励法可推广于当前分层岩层响应的计算．

Abstract: Propagation of stationary random waves in viscoelastic stratified transverse isotropic materials is investigated.The solid was considered multi-layered and located above the bedrock,which was assumed to be much stiffer than the soil,and the power spectrum density of the stationary random excitation was given at the bedrock.The governing differential equations are derived in frequency and wave-number domains and only a set of ordinary differential equations (ODEs) must be solved.The precise integration algorithm of two-point boundary value problem was applied to solve the ODEs.Thereafter,the recently developed pseudo-excitation method for structural random vibration is extended to the solution of the stratified solid responses.
