摘要

基于一个非线性粘弹性本构模型描述土体的蠕变特性，建立了有限元模型，对某工程中使用EPS作换填材料所产生的效果进行了计算模拟，讨论了主次固结沉降以及超固结状态的影响，探讨了工程中产生较大工后沉降的原因，预测了工程的远期沉降量，探讨了在该类工程中设计EPS的原则和方法。

Abstract

A nonlinear viscoelastic constitutive model is adopted to describe the creep properties of soft soil. Finite element model is established to simulate a project where EPS was used as substitutive material. The effect of EPS was computed. Primary consolidation

secondary consolidation and over consolidation are discussed. The causes of large settlement after construction are discussed. The long-term settlement of the project is predicted. The method and principle of designing EPS are discussed.
