マレーシア軟弱海成粘土地盤上に建設された試験盛土の変形挙動の評価

This paper describes the predicted and observed performance of full-scale trial embankment constructed on Maiaysian soft marine clays, and built to failure. Finite element analysis based on the Cam-clay model was utilized to investigate the defomation behavior of the embankment and the foundation soil until failure. Finite element solution based on shear band and deformation vectors agree well with the actual slip surface observed in the field measurements. However, more accurate prediction of slip surface requires careful assessment of the ground surface, corresponding to the actual mechanical behavior in the field during embankment.
