摘要： 采用砂井地基平面应变等效方法，结合ABAQUS软件对堆载预压下地基的侧向位移、沉降及孔压分布进行有限元模拟，并分析计算值与实测值之间的差异；计算结果能很好地预测砂井地基位移与孔压的变化, 可为地基处理的设计提供参考。

Abstract: This paper presents finite element analysis results using ABAQUS. The equivalent planestrain method is used to numerically simulate the vertical settlement, lateral deflection and pore water pressure distribution in soft soils improved by preloading using sand drains. The difference between the measured values and the simulated values are discussed. In general, numerical simulation can satisfactorily predict vertical settlement and the pore water pressure distribution.
