基于幂函数模型预估等截面抗拔桩单桩极限承载力的试验研究

Research on ultimate uplift capacity of tension piles of uniform section based on prediction of power function model

本文运用幂函数数学模型对抗拔桩Q-S曲线进行模拟,得出可以用来预估抗拔桩的极限承载力的Q-S曲线的幂函数模型,且通过工程实例验证该方法是可行的。

In this paper,the Q-S curves of tension piles are simulated by power-function math models,and the power-function math model which can be used to estimate the ultimate bearing capacity of the tension piles is put forward. And the math model which tested by the projects is feasible.
