| Abstract | The Finite Element approach was used to predict the movements and development of excess pore pressures resulting from the construction of embankments on soft clays deposits. Results are presented and compared to values observed in the field for two cases, an embankment built rapidly to failure on the soft Bangkok Clay and the loading to failure of an existing embankment on Interstate Route I- 95 near Boston, Massachusetts, U.S.A. It was found that the use of a value of yield stress of 0. 50 times the vane strength and modulus of elasticity of 150 times the effective overburden pressure or a yield stress of 0.65 times the vane strength and a modulus of elasticity of 70 times the vane strength gave reasonable predictions of the observed vertical motion and pore pressures of the embankment on the Bangkok Clay. However, a yield stress of 1. 2 times the vane shear strength and a modulus of elasticity of 250 times the original effective overburden pressure gave reasonable predictions for the I-95 embankment. |
