Crushed stone high filled foundation pile side friction testing method and device
The invention relates to a crushed stone high filled foundation pile side friction testing method and device. By adopting an active pressure application method, a large amount of testing time is saved. By adopting a jack pressurizing system, loads are controlled, control is convenient, and pile body axial force and pile surrounding friction distribution regularities under different load conditionsof test piles, changing rules of pile body axial force and pile surrounding friction along with the pile depth and change rules of the neutral point of negative friction along with the filling thickness and the pile surrounding stratum performance can be accurately simulated and tested.
本发明涉及一种碎石土高填方地基桩侧摩阻力测试方法及装置，采用主动施加压力的方法，节约了大量的试验时间；本方法采用千斤顶加压系统来控制荷载，便于控制，可准确模拟测得试桩在不同荷载条件下桩体轴力、桩周摩阻力的分布规律；桩体轴力、桩周摩阻力随桩深的变化规律；负摩阻力的中性点随填土厚度、桩周地层性能的变化规律。
