抄録: High embankment on soft clay layer is often associated with large settlement for long time, even if the failure of the embankment is not occured under construction. Presented herein is an analysis of time-dependant deformation of soft clay layer based on the elasto-plastic stress-strain-time relationship (the constitutive equation) of the cohesive soils previously reported by Tanabashi (1981). In order to verify the contitutive equation, several triaxial tests with complex stress pathes are performed. The finite element method incorporated the constitutive equation is applied to analyse time-dependant deformation of soft clay layer after the construction of road embankment in the bypass of route 3 in Onga-gun, Fukuoka. It has also been shown from the comparison between observed and calculated values that the proposed method estimates the settlement of the embankment with reasonable accuracy. Furthermore, the rate of contribution of each strain compornent to the deformation of soft clay layer is examined.
