Abstract:

As a result of the scarcity of land for construction, number of projects to construct man-made islands or to expand lands over soft grounds keeps increasing. Consolidation and creep are significant in the soft soil and hence, their long term deformation must be taken into account in engineering design and practice. Soil creep has significant impacts on the stability of the structures constructed on the soft ground. In this paper, a case study of an embankment constructed in stages in north Boston over a thick layer of Boston Blue Clay is numerically investigated in order to consider the effects of the soil creep. The behaviour of the ground is simulated using a finite element program associated with and without soil creep. A parametric study on the soil creep ratio is conducted to evaluate its effects on the predictions of the excess pore water pressure and lateral displacement. It is observed that the increase in the value of creep index causes the increases in both of the horizontal displacements and excess pore water pressures of the ground. In addition, the factor of safety against slope instability decreases with the creep ratio. Thus, the effects of soil creep should be earnestly considered in predicting the ground performance under embankments.
