A cantilever retaining wall of 7 meter height (Fig. Ex. 11.2) retains sand. The properties of the sand are: e=0.5, = 30" and G, = 2.7. Using Rankine's theory determine the active earth pressure at the base when the backfillis (i) dry, (i) saturated and (i) submerged, and also the resultant active force in cach case. In addition sdetermine the total water pressure under the submerged condition. - Backfill suhmerged e0.5 G,2.7 30 Dry backfill 7 m Sand Backfill saturated Water pressure P.-259 AN/m P41.2 KN/m AB is the wall considered P.48.81 AN/m- yH= 68.67 kN/m p.
