This paper presents the behavior of a geogrid-reinforced load transform platform supported by Geopier columns. For this purpose, the behavior of a test embankment constructed over soft ground in Gebeng, Pahang in Malaysia is investigated by comparing the field measurements made with those obtained from the numerical analyses. Numerical analyses were made using 3D finite element method by commercial code Plaxis 3D Foundation. In the analyses, the soil is modeled using an elasto-plastic constitutive model. Model parameters were obtained from laboratory and field tests. The field measurements compared well with the results obtained from the numerical analyses providing valuable insights regarding the load transfer mechanisms and the deformation of the embankment when it is constructed over a geogrid-reinforced load transfer platform supported on Geopier columns.
