CFG桩复合地基垫层调节作用研究

Study on the adjusting function of the cushion of the CFG pile composite foundation

通过理论分析,根据CFG桩复合地基的形成条件及桩土共同作用机理,探讨了CFG复合地基垫层设置的必要性及其调节作用,并论述了垫层的各种影响因素以及厚度选取的重要性,以使复合地基的受力更加合理。

Through the theoretical analysis,the necessary and adjusting function of setting the cushion are studied according to the forming condition of the CFG pile composite foundation and the operational mechanism of the soil and pile in this paper.And discusses the various affecting factors of the cushion and the importance of the mat layer thickness,so as to rationalize the bearing strength of composite foundation.
