Abstract

Abstract: Cement Fly ash Gravel (CFG) column composite foundation is one of the composite ground formed by the soil improvement methods. It receives wider applications since it has the advantages of simple construction equipment; easy installation; low overall cost and effectively improving natural weak ground. The researches on the mechanism on the CFG composite ground are fruitful in recently and many positive results are obtained. This paper presents the numerical analysis results of the performance of the CFG composite ground using ANSYS commercial software. Factors that might impact the performance of the CFG composite ground have been considered in the analysis.

Key words: CFG Columns, Composite Ground, Finite Element Software ANASYS, Stress Ratio between Column and Soil
