Computer Modeling for the CFG Pile in Highway Soft Foundation

Abstract:

In past 10 years, composite foundations, especially multipile composite foundations have been extensively used. Multi-pile composite foundation is a method of ground improvement that involves using different pile types with different lengths and diameters beneath the same raft. The CFG piles are generally much stiffer than lime piles and they are used in a manner similar to that used for conventional piles; that is, to mobilize bearing capacity from the deeper soil strata. This paper presents the results of a series of three dimensional (3D) finite element analyzes on CFG–lime composite pile foundations. The parameters investigated are the spacing of CFG pile and cushion thickness.
