A cohesive soil backfill has cohesion of 3 t/m², = and = 3 t/m³, the depth of tension crack developing in the backfill would be

A long slope is formed of a cohesionless soil, as shown below, making an angle of 25 wih horizontal. Soil has angle of internal friction, = 30, dry unit weight, = 16 kN/m³ and saturated unit weight, = 20 kN/m³. Find the factor of safety for the stability of the slope. Take = 9.81 kN/m³.

An 8m high retaining wall retains non-cohesive backfill of porosity = 0.40 and sp. gravity = 2.68. If angle of internal friction = 30 then active and passive earth pressure are___________, respectively.

A cut is to be made in a soil for a canal having side slopes of 1 to a depth of 8 m below the ground surface. The soil has cohesion of 15 kN/m², = 10, void ratio of 0.86 and specific gravity of 2.67. If the Taylor’s stability number is 0.17 and canal flows full then the factor of safety is

An inclined wall has to retain a backfill of soil of unit weight 16 kN/m³ and angle of internal friction 25 as shown in figure. If the weight of soil in region ABC is 26 kN per meter run then active thrust on the back wall is (height =10m)

Which of the following forces are taken into consideration in the friction circle method for the equilibrium of the sliding section in the stability analysis of slope (more than one answer may be correct)
