Influence of Geometrical Parameters of Soil-Cement Columns on the Average Settlement of Embankment on Reinforced Soft Soil – Numerical Analysis

Abstract

This article contributes to analyze the behavior of foundation on soft soil improved by soil-cement columns (SCC). Axisymmetric model is used in foundation settlement analysis by finite element method with geotechnical characteristics gathered from some typical projects in Viet Nam. Influence of geometrical parameters such as SCC diameter, SCC spacing and SCC length are considered
in these evaluations. The results clarify the behavior of reinforced ground base and offer recommendations for the choice of relevant geometrical scheme of SCC system to improve soft soil in transportation projects in Viet Nam.
