The example consists of the stability computations for the slope shown in Figure $1$ below.The slope consists of an embankment resting on a primarily sand foundation with a $0\mathrm{.}5$ mthick layer of soft, saturated clay.For Case $1,$ the factor of safety is calculated for the single, noncircular shear surface shown inFigure $1$ as a dashed line.For Case $2,$ an automatic search is conducted to find a more critical shear surface $($ifavailable$),$ beginning with the shear surface analyzed in Case $1.$For both scenarios, compute the factor of safety for the assumed slip surface usingappropriate slices. Use the required$/$appropriate equilibrium procedure$($s$)$ and otherassumptions during the limit equilibrium modeling.Explain whether or not you think the factor of safety that you calculated is a minimum. Notethat you have to support your answer with any relevant calculations from different solutions.Figure $1.$ Embankment resting on a foundation with thin, soft seam for example Case $1$ and $2.$
