11.7 A retaining wall of 6 m height having a smooth back retains a backfill made up of two strata shown in Fig. Prob. 11.7. Construct the active earth pressure diagram and find the magnitude and point of application of the resultant thrust. Assume the backfill above WT remains dry Cinder H, = 2 m G, = 2.5, n = 0.7 Q = 35° Sand H2 = 4 m G = 2.6, n = 0.3 o = 30° 2 m Figure Prob. 11.7

Question
Ask a a) Calculate the total active thrust on a vertical wall 5 m high retaining sand of unit weight 17 kN / (m ^ 3) for which phi = 35 deg The surface is horizontal and the water table is below the bottom of the wall. (b) Determine the thrust on the wall if the water table rises to a level 2 m below the surface of the sand. The saturated unit weight of the sand is 20kN / (m ^ 3) and you will be sure to find an answer!

4. The water table is located beloe the base of a rigid retaining wall 5 m high. The wall supports a backfill of cohesionless soil with 0= 30°. The backfill is dry and has a unit weight of 18 kN/m’. Determine Rankine’s passive earth pressure per meter length of the wall (Fig. Q4). WAV/AVAVIAN y = 18 kN/m = 30° 5 m Sand Figure 04
