FINITE DIFFERENCE ANALYSIS OF RELATIONS BETWEEN DESIGN PARAMETERS AND SETTLEMENT OF CFG PILE COMPOSITE FOUNDATION

Wan Lin-hai, Pingye Guo

Open publisher page 2 citations

Abstract

There are many factors affecting settlement and deformation of CFG pile composite foundation.In this paper,with the use of the finite difference analysis package FLAC-3D,these factors are analyzed systematically,including the cushioning layer,load,length of pile,modulus ratio of pile and soil,replacement ratio,modulus ratio of the soil around the pile and the soil under the pile tip,pile group and so on.The relationship between settlement and those factors are discussed,and the methods or measurements of reducing settlement are suggested.It is a useful reference for the practical engineering optimization design.
