摘要

有限元数值计算方法在岩土工程中已有较多的应用，但在水平受荷桩分析计算中的应用尚不普遍。有关水平受荷桩土体系水平承载力及变形的数值模拟方法少有文献报道。采用有限元数值模拟方法来研究水平受荷桩土体系的水平位移。首先简要分析了水平受荷桩的主要计算方法及原理。然后，基于ABAQUS软件建立了桩土系统二维及三维的有限单元模型，分别通过按现行规范推荐的m法和按Poulos的弹性理论法计算的两个算例，将数值计算方法与解析方法进行了对比计算分析。有限元数值计算结果与解析解基本吻合，说明了所采用有限元数值模拟方法的可靠性及有效性。

Abstract

Finite element method (FEM) has been widely used in geotechnical engineering

but relatively less in the analysis of laterally loaded piles. Few literatures about the numerical method simulating the loading capacity and deformation of laterally loaded piles-soils structure have been reported. The main purpose of this paper is to study the lateral deformation of laterally loaded piles by using FEM. First

The basic theories and methods of the laterally loaded piles are briefly analyzed; and then the 2-D and 3-D FEM models of pile-soil system are proposed by using the finite element analysis software ABAQUS. Differences between the FEM and the analytical solutions are compared through two illustrative examples calculated respectively by M-method which is used in the current code and by Poulos elastic theory method. Good agreement is found between the results from FEM calculation and the analytical solutions

which proves the reliability and efficiency of the FEM model given in this paper.
