QUESTION 4. A retaining wall 6 m high with a vertical back face retains a homogenous saturated soft clay. The saturated unit weight of the clay is 19 kN/m3. Laboratory tests showed that the undrained shear strength, Cuof the clay is 16.8 kN/m3, f=0o. Do the necessary calculations and draw the variations of Rankine’s passive pressure on the wall with depth Determine the total passive force per unit length of the wall. Find the location of the resultant force?
