The critical slip circle for a slope is shown below along with the soil properties. The length of the arc of the slip circle is 15.6 m and the area of soil within the slip circle is 82 $m^2$ . The radius of the slip circles is 10.3m. The factor of safety against the slip circle failure is nearly equal to

📖 Explanation

\begin{aligned} \text { FOS } &=\frac{\text { Resisting moment }}{\text { Actuating moment }} \\ &=\frac{C L R}{W \times 2.3}=\frac{30 \times 15.6 \times 10.3}{20 \times 82 \times 2.3} \\ &=1.28 \end{aligned}
