摘　　要：对土体采用Mohr-Coulomb弹塑性本构模型,用接触面单元模拟结构物–土相互作用,利用ABAQUS软件建立水池–桩基的三维有限元分析模型,分析了水池从施工到使用各个工况下格形地下连续墙的位移以及邻近桩基的附加变形,最后通过对比,探讨了桩基的存在对地下连续墙变形产生的积极影响,取得了水池施工与邻近桩基相互影响的基本认识,对于改进桩基础设计方法有一定的参考意义。The Mohr-Coulomb's model and the contact surface model are adopted to simulate the characters of soils and the interaction between structures and soils respectively. A 3D finite element model based on the interaction of pool and piles is established by ABAQUS software. The displacement of latticed concrete diaphragm wall and the additional distortion of adjacent piles during the construction state and the service state are analyzed. Finally, comparisons indicate that the piles have a positive effect on the concrete diaphragm wall. Through this study, the basic knowledge of the interaction between the pool construction and the adjacent piles are initially obtained, and it will be significant to the improvement of theories for piled foundation design.
