Abstract:
In this study, an evaluation has been performed on a numerical model by the code of PLAXIS based on finite element method to see the effect of stone columns (SCs) placed vertically in a soft soil slope in terms of slope stability and settlements. Effect of s/D ratios (distance between the vertical axes of SCs/diameter of SCs) was investigated on slope stability and settlement of embankment. This study, analyzed numerically in two dimensions under plain strain conditions by Mohr–Coulomb model. The analysis were performed by the PLAXIS code for various slope angles β, ratios of c/(γH), and ratios of s/D. It was observed that settlements were decreased after the improvement with SCs. From the analysis performed, it was found that the SCs increased the stability of slope 1.14- to 1.72-fold as a relative effect of different parameters.
