主要运用数值模拟方法研究了置换率与桩的长径比对CFG桩复合地基性能的影响,得出了CFG桩复合地基中CFG桩应有一个经济合理的长度,并且给出了合理的置换率范围。
The effect of displacement ratio and the aspect ratio of the CFG pile composite foundation is mainly studied by means of numerical simulation. It is concluded that the CFG pile in the CFG pile composite foundation should have an economically reasonable length, and a reasonable replacement rate range.
