A 21 foot high retaining wall supports a purely cohesive soil (o = 0°) with a cohesion of 630 psf and a unit weight of 113 pcf. Find: (a) The Rankine active earth pressure on the wall. (b) Estimate the depth of separation of the clay from the wall, and (c) find the lateral force upon the wall whilst considering the clay separation. 21 ft yzK, - 2c/K.
