The total active thrust on a vertical wall 3m high retaining a horizontal sand backfill (unit weight γt = 20 kN/m3, angle of shearing resistance φ' = 30°) when the water table is at the bottom of the wall, will be:-A-30 kN/mB-35 kN/mC-4 kN/mD-45 kN/m-A-30 kN/m

Question

The total active thrust on a vertical wall 3m high retaining a horizontal sand backfill (unit weight &gamma;t = 20 kN/m3, angle of shearing resistance &phi;&#39; = 30&deg;) when the water table is at the bottom of the wall, will be:-A-30 kN/mB-35 kN/mC-4 kN/mD-45 kN/m-A-30 kN/m

APTITUDE CRACK · Accepted Answer

A 30 kN/m Active thrust = 1/2(ka*H^2*yt). Ka = 1 sin30/1+sin30 = 0.333. = 1/2(0.333*3^2*20). = 30 kN/m.
