推力桩计算方法的研究

STUDY ON CALCULATION METHOD OF LATERALLY LOADED PILE

本文是作者多年对推力桩桩-土共同作用研究的综合成果,提出了计算推力桩的综合刚度原理和双参数法以及参数的确定,能使推力桩在地面处的挠度、转角、桩身最大弯矩及其所在位置等主要工程指标的计算值同时与实测值很好地符合.它比p-y曲线法具有更多的优点.

This paper introduces the principle of the composite stiffness and the method of biparameter proposed by the author for calculating laterally loaded pile, and a series of models for determining the nonlinear subgrade, reaction coefficients. By use of the method, the calculated main engineering indexes of pile, i. e. the deflec tion and slope at the ground surface of the pile, the maximum bending moment and its position, can agree well with the measured ones simultaneously. Hence the method proposed in this paper is better than that of the p-y curves fitting.
