A granular soil of thickness 4 m has G = 2.70, e = 0.5, and ϕ = 35°a. A slope has to be made of this material. If a factor of safety of 1.15 is needed against failure. (γ sat = 20.98 kN/m3, γd = 17.658 kN/m3, γw = 9.81 kN/m3) Which of the following are true.
1
Angle of slope when seepage occurs at and parallel to surface of the slope is 17.92°
2
Angle of slope when seepage occurs parallel to the slope with water table at a depth of 1.5 m from top is 20°
3
Angle of slope when seepage occurs at and parallel to surface of the slope is 31.36°
4
Angle of slope when seepage occurs parallel to the slope with water table at a depth of 1.5 m from top is 22.75°
