| 摘 要： | 通过现场原位试验,绘出了单桩P-S曲线和复合地基P-S曲线,分析了CFG桩复合地基受力过程,桩土应力变化规律以及桩土应力比的变化趋势,通过在不同荷载作用下,反算桩间土承载力发挥系数,提出一个比较保守的系数,同时得到一些较有意义的结论,以供工程参考。

| Abstract: | According to an in-situ soil test,the P-S curve of the single pile and the P-S curve of the composite foundation were drawn.The loading process,pile-soil stress ratio and its changed rule of CFG pile composite foundation were analyzed.Based on the reaction of different loads,the coefficient of the bearing capacity of the soil between piles was computed and a conservative coefficient was proposed.The results and conclusions were drawn in this paper and can be referred by the engineering design. |
