摘要
在单桩静载荷试验的研究过程中,通常借助函数关系对Q-s曲线进行数学分析。本文为得到较高拟合度的函数关系参数,采用函数曲线拟合单桩静载试验Q-s曲线,通过拟合参数求取Q-s曲线函数关系,然后进行比选,最终确定一种拟合度最高的函数关系。利用函数关系,可预估桩基沉降值,也可利用沉降值反算上部荷载。
In the process of single pile static load test, mathematical analysis of Q-s curve is usually done by means of function relation. In order to obtain the function relation parameter of higher fitting degree, the function curve is used to fit the Q-s curve of the static load test of single pile, and the relation of Q-s curve function is obtained by fitting parameters, then the comparison is carried out,and a function relation with the highest fitting degree is finally determined. The settlement of pile foundation can be predicted by using function relation, and the upper load can be calculated.
