摘要
本文用有限元法对香港地区桩的摩擦力进行了研究。采用邓肯－张模型和修正剑桥模型，并设置了古德曼的接触面单元，计算结果与实测数据较吻合。同时，论述了在桩的负摩擦分析中考虑土的弹塑性特性及接触面单元的必要性。
Finite element analysis of negative skin friction on a steel pile in Hong Kong is presented in this paper.Goodman's interface elements together with Duncan-Chang's model and Modified Cambridge model are used.The calculated results agree well with field measurements. The neceasity for considering elastoplastic behaviors of soilcoupled with interface elements in the analysis of negative skin friction on piles is demonstrated.
