Q.1. Refer to the infinite slope shown in Figure 1. Given: B = 29 °, y = 21 kN/m3, Ø = 32 °, and c' 37 kN/m2. Find the height, H, such that a factor of safety, Fs 3 is %3D maintained against sliding along the soil-rock interface. b. Determine the thrust on the wall if the water table rises to a level 1 m below the surface of the sand. The saturated unit weight of the sand is 22 kN/m3.
