| 摘 要： | 采用积分变换与积分方程研究了单层饱和地基上刚性基础的竖向振动问题.首先从饱和土的动力控制方程出发,考虑混合边值条件,获得了一组描述基础振动的对偶积分方程,进而给出了单层饱和地基表面的动力柔度系数.该文的工作可视为对饱和半空间地基上基础振动解答的推广.

| Abstract: | The vertical vibration of a rigid circular footing resting on a single-layered saturated ground is studied by employing the method of Hankel transform and integral equation. The paper starts with the governing differential equations for saturated soils. Under the consideration of the mixed boundary value condition, a pair of dual integral equations governing the vertical vibration of the rigid footing are then obtained. Consequently ,the dynamic compliance coefficient C v for the single-layered ground is evaluated. The present study extends the analysis of dynamic response of foundations on grounds from the saturated half-space to the layered soils. |
