结合嵌岩桩现场实测数据,采用正弦函数来拟合桩侧摩阻力与桩-土相对位移之间的关系,由此导出了无限长桩的桩-土相对位移函数;同时采用负指数函数拟合桩端阻力与桩端位移之间的函数关系,进而求得桩侧摩阻力和桩端摩阻力,从而得出桩顶沉降量与竖向承载力之间的关系。最后结合嵌岩桩静载荷试验进行分析,该计算方法与实测结果吻合良好。 Combined with the measured data of rock-socketed pile, the sine function is used to fit the relationship between pile-side friction and relative displacement of pile-soil, and the relative displacement function of pile-soil is deduced. The negative exponential function Pile end resistance and pile displacement as a function of pile displacement, and then get the pile side friction and pile friction, so as to draw the relationship between the pile top settlement and vertical bearing capacity. At last, the static load test of rock-socketed pile is analyzed, and the calculation method is in good agreement with the measured data.
