基于P-Y曲线法考虑桩土相互作用的高桩结构物分析

ANALYSIS OF HIGHPILE STRUCTURES BASED ON PY CURVE METHOD WITH CONSIDERATION OF INTERACTION BETWEEN PILE AND SOIL

ＰＹ曲线法是一种非线性地基反力法，可用于分析横向荷载作用下桩结构物，尤其在分析有较大变位的桩结构物时，有许多突出的优点。本文就ＰＹ曲线法分析横向力作用下的高桩结构物的实施方法、特点进行了研究，编制了相应的程序，结合算例给出一些供工程设计人员参考的结论。

PY curve method is a nonlinear soil reaction force method.It possesses many advantages when adopted for the analysis of pile structures under lateral loads,especially for the analysis of the pile structures with large reflection.In this paper,the implementation process of PY curve method employed for the analysis of pile structures is studied and the corresponding program is coded. Based on the examples,some conclusions are provided for the designers.
