【摘要】 根据结构力学中的位移法及有限元的基本理论,考虑了接触面的剪切力和剪切变形之间的非线性关系,导出了分析大直径桩土相互作用的有限元法,编制了计算程序,并与试验结果进行了对比分析。结果表明,计算分析结果与实测桩基承载力吻合良好。更多还原

【Abstract】 According to displacement method in structure mechanics and finite element theory, and in terms of the nonlinear relation between shearing force and shearing deformation, this paper introduces a finite element method designed for analyzing the interaction between large diameter pile and soil, meanwhile the paper presents a calculation program and highlights the comparative analysis of the experiments. As indicated in the paper, analysis result proves a better engineering performance.更多还原
