半透水边界饱和土层在循环荷载作用下的一维固结分析

1-D consolidation analysis of saturated soil with semi-pervious boundaries under cyclie loads

本文基于Terzaghi一维固结假设 ,研究分析了半透水边界饱和土层在循环荷载作用下有效应力比的变化。利用Laplace变换 ,得到了随时间任意变化荷载作用下的解答 ,并结合数值Laplace逆变换方法 ,对几种常见的荷载进行了讨论 ,研究了土性参数对固结的影响 ,得到了一些有益的结论 。

Based on Terzaghi's 1 D consolidation theory, the consolidation problem of saturated soils with semi perivous boundary under cyclic load is solved by means of Laplace transform. Influences of different kinds of cyclic loads, boundary conditions and parameters of soil on consolidation are discussed. with numerical inversion of Laplace Transform. some results are illustrated, which are meaningful to engineering practice.
