| 摘 要： | 基于Terzaghi一维固结假设,研究分析了半透水边界的粘弹性土层在循环荷载下的一维固结问题。利用Laplace变换,得到了随时间任意变化的荷载作用下的解答,并结合数值Laplace逆变换,对几种常见的荷载进行了讨论,得到了一些有益的结论,可以用于指导工程实践。

| Abstract: | The 1-D consolidation of a viscoelastic soil layer under cyclic loading is studied in the paper. The soil layer is in the state with semi - permeable boundaries. It is based on the Tezaghi theory. The Laplace transfonn is used in the study. At last, the solution to the time - dependent load is obtained. The influences of the different cyclic loadings and the semi - permeable boundaries are both discussed in details.Some results are illustrated with the numerical inversion of Laplace transform. |
