Abstract

This paper describes a simple procedure for evaluating deformation behavior of clay foundation under embankment, using a soil-water coupled finite element method based on finite deformation with elasto-plastic model, and a simplified method for determining the soil parameters and ground modeling estimated by liquid limit, plasticity index and natural water contents. Reasonable agreements have been obtained between measured and computed values for vertical and horizontal deformations of the well documented case history of the Kurashiki trial embankment built on soft ground. Finally, the analytical results obtained by the present methods are found to be reasonable in the preliminary design, considering the idealized assumptions made and uncertainties in the data.
