结合某高速铁路CFG桩复合结构加固软土地基的方案,采用数值分析手段,对CFG桩复合地基的基础结构类型、有无桩帽、桩距等参数对地基变形的影响进行分析,结论认为:随着基础结构刚度的增加,路基中心的沉降明显减小;地基的不均匀沉降明显得到均化;设置桩帽可以与减小桩距或增加垫层刚度达到相同效果。
Combined with the scheme of a high-speed railway CFG pile composite structure strengthening soft soil foundation, numerical analysis method is used to analyze the influence of foundation structure type, pile cap, pile pitch and other parameters on the foundation deformation of CFG pile composite foundation. The conclusion is: As the stiffness of the foundation increases, the subsidence at the center of the subgrade is obviously reduced. The uneven subsidence of the foundation is obviously homogenized. The pile cap can be installed with the same effect of reducing the pile spacing or increasing the cushion stiffness.
