摘要：
This paper performs a numerical method to analyse the influence of replacement area ratio to behaviours of soft soil foundation reinforced with soil cement columns. The analysis bases on the finite element method (FEM) and Plaxis 2D software to simulate a cylindrical unit cell of soft soil. The cylindrical unit cell includes a soil-cement column and the surrounding soil. In order to estimate the influence of replacement area ratio, the following factors are analysed: the consolidation settlement (the settlement of foundation after consolidation process finished), degree of consolidation, and the improvement factor. Results show that, the replacement area ratio increases, the consolidation settlement increases, accelerate the consolidation process of foundation, also increases the improvement factor. Besides, based on data of this study, an equation fit by regression shows the relationship between the improvement factor and the replacement area ratio. © 2015 ejge.
