粉土场地CFG桩沉降计算经验系数取值分析

Value Analysis of Computing Experience Coefficient with CFG Pile Settlement in Silt Site

根据粉土场地工程案例的现场试验结果,确定了CFG桩复合地基中有效应力分布规律及影响深度;研究了CFG桩复合地基沉降计算模型的适用性;对比分析了规范方法计算模式和实测沉降量计算结果,提出了在粉土场地CFG桩复合地基沉降计算经验系数的取值。

The distribution regularities and influence depth of effective stress were determined according to the results of test in silt site.The author studied the model applicability of the CFG pile composite foundation,analyzed the difference between the calculated date from code and actual measured data,and concluded the empirical coefficient of CFG pile composite foundation settlement in silt site.
