Question-3:
(i). For the given failure surface, determine the factor of safety in terms of total stress for the slope given in the Figure 01. The unit weight for both soils is 19 kN/m3. The characteristic undrained strength (cu) is 30 kN/m2 for soil 1 and 45 kN/m2 for soil 2. What is the factor of safety aginst slope failure?
(ii). Which method of slope stability analysis you would use to evaluate long term stability of the slope shown in Figure 01, and Why?
