An MSE wall is 7 m high. The wall retains a roadway section consisting of a 0.5 m clear zone a 2.5 m wide shoulder and 2 lanes of traffic which are 3 m wide each. The unit weight of the retained fill is 20 kN/m3 and the shear strength of both the retained fill and the foundation soil is 30 degrees with no cohesion. If the traffic surcharge is equivalent to a uniform live load equal to 10 kN/m2 determine the following:
A preliminary length of reinforcement
The horizontal forces acting on the reinforced fill volume
The factor of safety against sliding
