成层地基半透水边界一维固结分析

On One Dimensional Consolidation Behavior of Layered Soil with Partial Drainage Boundaries

本文在Terzaghi模型基础上,考虑了半透水边界条件和逐渐加荷条件,求解出一维固结解,并根据该解详细研究了成层土有别于单层土的一些固结特性以及半透水边界、土层性质、加荷速率等对超静孔压及地基固结度的影响,并通过算例说明了解的应用。

In this paper, based on Terzaghi's model an analytical solution is given for one dimensional consolidation of layered soil with partial drainage boundaries under time-dependent loading. By using the solution, the distinction of the consolidation behavior between layered soil and homogeneous soil is investigated and the influences of partial drainage boundary, the characteristic of soil, as well as loading rate on the consolidation behavior are discussed. Finally, numerical example is presented to illustrate the applications of this solution.
