A 10 m deep canal is constructed in purely cohesive soil having c = 0·2 kg/cm2, θ = 0°, G = 2·5, e = 0·5. The stability number is 0·1. In a canal running in full condition, the factor of safety w.r.t. cohesion against failure of side slopes will be
Failure of slopes occurs only when a total shear force is
In a clayey soil having 50 kN/m2 as unit cohesion and 18 kN/m3 as unit weight, an excavation made with a vertical face. Taking Taylor’s stability number as 0.261, what is the maximum depth of excavation so that the vertical face remains stable?
For the construction of a highway a cut is to be made as shown in the figure.The soil exhibits c’= 20 kPa, ϕ’ = 18°, and the undrained shear strength = 80 kPa. The unit weight of water is 9.81 kN/m3. The unit weights of the soil above and below the ground water table are 18 and 20 kN/m3, respectively. If the shear stress at Point A is 50 kPa, the factors of safety against the shear failure at this point, considering the undrained and drained conditions respectively, would be
During stability analysis, the term mobilised shear strength means
