摘　　要：以某人工岛机场项目为依托,分别采用经典土力学理论和有限单元法分析了成层土地基施工期沉降及工后沉降,为确定地基处理方案提供依据。通过计算结果对比分析,表明采用化引当量层法计算成层土地基一维固结沉降能够满足工程精度要求。Based on an artificial island project,this paper calculates the settlement of layered clay foundation during construction and after work by classical soil mechanics theory and finite element method separately.The results provide a basis for the determination of the technical scheme.The analysis results show that equivalent layer method gives pretty realistic results of the degree of consolidation for layered clay.
