Consider a vertical wall 3 m high. The soil behind it is a clean loose sand, specific weight= 17:6kN/m3 ; phi = 36.
The backfill is level. Determine the following:
(a) Total force on the wall, at-rest conditions.
(b) Location of the resultant.
(c) Magnitude of lateral earth pressure at top of wall.
(d) Magnitude of lateral earth pressure at base of wall.
(e) The force on the wall for the Rankine active condition.
(f) The distance the top of the wall must rotate to achieve full Rankine active pressure.
(g) The force on the wall for the Rankine passive condition.
(h) The distance the top of the wall must rotate to achieve full Rankine passive pressure.
