| This paper presents the results of a research performed to investigate the finite element modeling approach for GESC (Geogrid-Encased Stone Column) method in soft ground within the framework of stress-pore pressure coupled analysis. GESC reinforcement mechanism and construction method was first examined and model verification of stone column on the results of FE analysis was identified. The results indicate that the 3D FE analysis and membrane elements play the most important role in the soft groung using GESC. Based on the results, a modeling method was suggested for stress-pore pressure coupled finite element modelling of GESC in soft ground. |
