摘要

针对单层黏弹性地基模型，对循环荷载作傅立叶级数展开，由固结方程求得循环荷载作用下不透水（透水）边界饱和软黏土一维固结解析解。通过不同渗透系数、黏滞系数和弹性模量以及黏弹性与弹性不同地基模型比较等对有效应力的影响，进行了固结性状分析。结果表明、在循环荷载作用下地基中各点的有效应力并不随荷载的变化而同步变化，而是按一定规律滞后发展；有效应力最终达到一个稳定状态，每一个加载卸载循环下有效应力幅值在一个振荡周期的平均值变化趋近于0；软黏土的流变特性对固结的影响主要发生在中、后期。

Abstract

The analytical solution is presented to one dimensional viscoelastic consolidation problem of soft clay with impervious boundaries and pervious boundaries under cyclic loading that has been Fourier expanded. The influence of some parameters

such as permeability coefficient

viscosity coefficient and elastic modulus

etc. and different constitutive relation conditions on the consolidation is investigated. It is shown that the effective stress reaches the stabilized state in the end with certain amount of cycles. The rheological feature of saturated clay mainly functions in the intermediate and long-term stage of consolidation.
