Vertical and horizontal deformation of foundations under embankments is often large and potentially damaging to structures. Evaluating the magnitude of such deformation and the rates at which they occur play an important part in many geotechnical engineering projects. This deformation analysis becomes increasingly important when embankments are constructed on weak soils. To confirm the applicability of the simplified deformation analysis as proposed by KAMEI,deformation analysis was carried out using Finite Element Method analysis available in commercial software. The model simulations are compared with thewell-documented case history of the Kanda trial embankment. Reasonable agreement is obtained betweenthe measured and the computed values of ground surface movements beneath the center of the embankmentfor the multi-soil layers in the preliminary design. We also evaluated whether it is possible to reduce operations and shorten the total construction period and cost using by this analysis. According to our results,significant reduction in operations and shortening of the total construction period is possible. Finally,signiicant information in engineering practice is gained by this analysis.
