A retaining wall with a smooth vertical back retains sand backfill for a depth of 6m. The horizontal backfill has the following properties. d' = 0, y = 16KN/m³; Vsat = 20k N/m³. Calculate the magnitude of total thrust against the wall for given conditions: (a) backfill fully drained but the top of wall is restrained against yielding: (b) backfill fully drained and the wall is free to yield, and (c) wall free to yield, water table at 3m depth without drainage. Determine the point of application for the resultant thrust case(c).
A retaining wall supports a horizontal backfill that is composed of two types of soil. First layer: 4.84 meters high, Unit weight of 17.36 kN/m3, coefficient of active pressure of 0.285 Second layer: 5.68 meters high, Unit weight of 18.9 kN/m3, coefficient of active pressure of 0.307 Determine the distance of the total active force measured from the bottom of the wall.

A thin clay layer passes through the soil at an angle of 30° behind an 8m high gravity retaining wall. A structure 5m wide, applying a uniform stress of 40kPa to the sandy soil, also acts on this section of soil as shown in Figure 3.1. The properties of the clay are ??=25???, ∅?=0, ?′=0 and ∅′=20°. The sandy soil properties are ?′=0, ∅′=35°, ????=16??/?2, ????=20??/?2, and between the sand and the wall the properties are ?′?=0 and ∅′?=30°. Assuming that failure occurs along the clay layer, use Coulomb’s method to calculate the horizontal force required from the wall in the short term to prevent slip.
