摘要
通过长螺旋钻孔管内泵压CFG桩与长螺旋钻孔管内泵送无压力成桩及钻孔灌注成桩等三种不同工法的试验桩的低应变桩身完整性检测和静载荷试验对比分析 ,得出三种工法成桩的桩身结构均完整 ,但是长螺旋钻孔管内泵压CFG桩无论桩周摩阻力还是桩端承载力均比钻孔灌注桩高 。
Based on the low strain dynamics test and loading test, the Bearing Behavior of three types of CFG pile using continuous flight augers drilling(pressure pumped CFG pile, non pressure pumped pile and casting pile)is described in This paper. Moreover, the skin friction and the end resistance of these piles are discussed.
