| 摘 要： | 为了进一步了解大直径管桩在水平力作用下的工作性状,文中基于有限元方法对水平承载桩的受力变形进行了模拟分析,考虑到土体的非线性因素以及桩-土界面的接触特性,引入了界面接触单元,利用惩罚函数的算法对其工作性状进行了综合分析,并分析了在分级加载作用下的桩身内力的分布模式和变化规律。

| Abstract: | To reveal the performance of the large-diameter pipe piles under lateral loads,the nonlinear beha-vior of soil as well as the contact behavior of the pile-soil system are considered.A calculation model is established by means of the finite element method with the contact elements introduced.By using the penalty function,there is a comprehensive analysis on the working behavior of pile-system.The distribution of internal forces and the alteration pattern of the pile under gradual loads are also analyzed. |

| Keywords: | pipe piles lateral force finite element contact element penalty function |
