| 摘 要： | 用积分变换方法分析饱和土三维非轴对称波动方程，用刚度矩阵方法分析层状饱和土三维非轴对称稳态响应。以数值算例对比分析了单相土介质与两相饱和土介质三维非轴对称稳态动力响应。分析中未引入势函数及传统的Helmholtz分解，推导过程及解答均非常简捷，为边界元方法在三维非轴对称饱和土与基础结构动力相互作用研究中的应用奠定基础。

| Abstract: | By means of integral transform, dynamic equations of the 3 D non axisymmetric layered saturated soils are solved. Based on these fundamental solutions, a stiffness matrix of layered saturated is derived exactly. A comparative analysis for stable response of dry soils and saturated soils is performed. Without the aid of traditional theory and Helmoholtz's decomposition, the analyzing procedure and solutions become very simple and direct, which will be used as foundation of applying boundary element method in dynamic interaction between saturated soils and structure. |
