摘要
根据工程软弱土层进行复合地基处理后的静载荷试验结果,对CFG桩、桩间土荷载分担及桩土应力比随外荷载的变化规律进行了分析,提出了本次试验的极限桩土应力比。这些试验结果和分析结论对指导西南地区软弱土地基处理与加固有一定的参考价值。
According to the static loading test in a soft soil construction site after a composite foundation treatment, we analyze the change laws on the CFG pile, the load sharing between piles and soil, and the pile - soil stress ratio following with load. Then we put forward the limit pile - soil stress ratio of this test. These test results and our analyses are valuable for the treatment of soft soil foundation in the southwest areas of China.
