Stability Charts for Fill Slopes Based on Finite Element Limit Analysis Methods
Slope stability assessment is extremely important in geotechnical engineering, as it prevents slope failures and the loss of lives. This paper utilizes the finite element lower bound limit analysis method to investigate and develop a set of 3D stability charts for fill slopes where frictional fill materials are placed on undrained clay with increasing shear strength with depth. Based on the stability charts, preliminary slope designs can be performed with convenience and ease, which is advantageous during the preliminary design stage when options and cost-saving solutions are more important than detailed design. Additionally, for comparison purposes, the results from twodimensional analyses are also presented and discussed. This study shows that the ratio of F3D/F2D is always larger than unity. Discussions on the factors affecting the failure mechanisms of this type of slope are also presented. In particular, a better understanding of such failure mechanisms allows engineers to better predict the footprints and consequences of the failures of such slopes.
