Behaviour of ground improvement techniques on embankment using plaxis 2D version 8.6

Parametric study of consolidation behaviour of improved embankments on soft ground is studied by using a numerical model based on Finite Element Method (FEM) in Plaxis version 8.3. This project is emphasis on parametric study of the consolidation behaviour of three finite element (FE) models of improved embankment with preloading, prefabricated vertical drain (PVD) and stone column. These three FE models are compared with unimproved embankment, which is no improvement technique applied. The comparison between four FE models is focused on the prediction of excess pore pressures dissipation, vertical and horizontal displacements. The ability of Plaxis to simulate future predictions of the effect of ground improvements to the soft soils are validated by computing and comparing all three FE model for improved soil with unimproved soft ground which has the same characteristics of Muar Test Embankment. The validation of the analysis results are made in terms of excess pore pressures, vertical and horizontal displacements. Highest rate of improvement found in between the three models are chosen as suitable techniques to solve the problems relating to soft ground
