A vertical wall is 8m high and it retains a fill material. The upper 2m of the fill has density of 2000kg/m^3, angle of friction is 20° and unit cohesion c=25Kpa on the horizontal surface of the fill. The lower layer of the fill is fully saturated and has a saturated density of 2100kg/m^3, angle of friction is 25° and unit cohesion c=20kpa. Calculate the thrust exerted on the retaining wall and the height of the resultant thrust above the base of retaining wall.
