3. A cut slope consist of soil materials that has a unit weight of 16 KN/cu.m and undrained shear strength = 28 KN/sq.m. The slope makes an angle of 50° with the horizontal. Assume a stability number of 0.17. Determine the stability factor b. Determine the maximum height to which the cut could be made Determine the angle that the failure plane makes with the horizontal if BA=7.6m. a. C. В 7.6 m А Hcr = 12.3 failure plane

Please answer (a)

From the figure shown the soil has a unit weight of 28.5 kN/m^3 and the undrained shear strength cu = 20 kN/m^2. The slope makes an angle 62 degrees with the horizontal. Assume a stability number m = 0.16761. Compute the stability factor. a. 6.78b. 6.7c. 5.99d. 5.012. Compute the maximum depth up to which the cut could be made. a. 5.18 mb. 4.97 mc. 4.20 md. 3.84 m3.
