| 摘 要： | 应用非线性有限单元法和ANSYS软件,采用四面体等参单元和面-面接触单元对多年冻土区大直径钻孔灌注抗拔桩承载性能进行了数值仿真分析,得到了单桩极限抗拔力与现场荷载试验结果比较吻合.说明本文采用的分析方法能够客观反映多年冻土区桩-土相互作用的力学行为.

| Abstract: | Applied with non-linear finite element method and ANSYS software,the tetrahedral structural element and surface-to-surface contact elements are adopted to large diameter cast-in-site uplift pile's bearing capacity numerical analysis in permafrost,the calculated limit pulling resistance and its test result are basically inosculated.It shows that the method used in this paper can be truly reflecting the behavior of pile-soil interaction in permafrost. |
