Cement stabilized soil reinforced by geogrid for sea wall called SG-wall has already been found its efficiency based on the model test results to increase the strength of the reinforced soil block and to resist separating. This reinforced block is aimed to apply for construction of sea wall encountered with deepening sea bed and as a countermeasure against earthquake. This paper presents the applicability of three numerical models to predict deformation and ultimate strength for reasonable designing procedure. Three types of modeling are Winkler model, crack models that extend in the surface zone and develop in the vertical direction. As result, vertical crack model is found to give a approximate value corresponding to the test results.
