... resistance. This paper describes the behaviour of an embankment stabilised with vertical drains, where a specific case history is selected from Malaysia. The consolidation of soft clay is modelled on the basis of the modified Cam-clay. The settlement behaviour at various stages of embankment loading...

... means of allowing the construction of embankments over soft soil deposits. It is noted that while basal reinforcement can increase stability and reduce short term shear deformations, it can not prevent long term consolidation and creep settlements. However when the use of basal reinforcement is combined...

... deformation due to the fluid flow during reservoir fluid production can be described by a general three-dimensional deformation field coupled with a three-dimensional fluid flow field. A fully coupled numerical model is developed based on the generalized Biot consolidation theory. For showing the application...

To estimate their effects, it is necessary to investigate how the excess pore water pressure in the clay layer varies with the time and to analyze the interaction between the ground and structure. We present the correlation between the mean consolidated pressure, and the coefficient of volume...
