A Figure Q3 A Shows A Cut Slope Which Consists Of Homogeneous Residual Clay Soil Based On Total Stress Analysis Det 1 (48.93 KiB) Viewed 24 times

a) Figure Q3 (a) shows a cut slope which consists of homogeneous residual clay soil. Based on total stress analysis, determine the factor of safety using the given trial toe failure surface for which the radius is 7.2 m. The centroid 'G' is located 3 m to the right of the centre of the trial circle. Explain briefly why the undrained shear strength value is considered uniform throughout the failure surface. The soil properties are: c₁ = 40kN/m², p = 0, 7 bulk = 18kN/m³. (CO1,PO2)(C4) 0.8m A 2.0m 2.0 m 87.5° 2.2 m 2.0 m 7.2 m 2.5 m G 2.0 m Figure Q3 (a) 2.5 m 2.0 m 2.0 m 6.0 m (9 marks)
