Yan, Z., Li, A.J. and Merifield, R.S. 2013, Slope stability analysis for cohesive materials filled on purely cohesive undrained clay, in 18SEAGC/1AGSSEA 2013 : Proceedings of the 18th Southeast Asian Geotechnical Conference cum Inaugural AGSSEA Conference, Research Publishing, Singapore, pp. 519-524, doi: 10.3850/978-981-07-4948-4_053.
Stability charts for soil slopes were first produced by Taylor in 1937 and they continue to be used extensively as design tools and draw the attention of many investigators. From a review of literature, it was found that there is no convenient solution has been provided for cohesive materials filled on purely cohesive undrained clay. A recent study revealed that the embankment slope which has two-layered clays failed in an undrained state which shows the importance of this study. In order to obtain the solutions for this type of fill slope. A number of numerical method are employed, namely the finite element upper and lower bound limit analysis methods and limit equilibrium method. The numerical upper and lower bound limit analysis method can bracket true solutions within a small range (6%). The solutions of limit equilibrium analysis are used for comparison purpose.
