摘要 研究了成层土的动力响应计算方法 ,推导了有关公式 ,并给出了移动荷载作用下的时程曲线。这一方法同样可用于分析冲击荷载所引起的场地土效应。 The soil dynamic response based on finite elastic layer is investigated. The ground is modeled by stratum on rigid base and the ground characteristic is analyzed in the frequency-wave number domain for the wave propagation. The method is also used for the case of impact loads induced soil response.
