侧向荷载桩的非线牲分析

NONLINEAR ANALYSIS OF LATERALLY LOADED PILES

本文给出了由试桩实测弯矩建立P-y曲线的一种新途径。其特点是概念清晰、运算简便、准确,为确立P-y曲线及地基系数的分布规律提供了有力的工具。本文还提出了用P-y曲线进行侧向荷载非线性分析的有限元数值方法。对镇江大港原型试桩采用上述方法进行了分析。

In this paper, a new method to establish p-y (soil reaction-pile deflection) curve by using measured test pile moment has been presented. This method is clreain conception and convenient in use. It give a effective means for determining the distribution pattern of p-y' curve and subgrade modulus. In this paper, a finite element numerical method of nonlinear analysis for lateral lyloadedby p-y curve also has been presented. By means of the method, a full-scale test pile in Zhenjiang Port has been analysed.
