Chapter 12, Problem 12.13P

Where, X=36 A retaining wall (frictionless) is shown in a) Plot the variation of active and passive lateral pressures with depth for soil profile shown in Fig.1  b) Determine the force due to surcharge in active side c) Compute Total active force on the wall if the wall is 9m long  d) Evaluate the lateral stability of the wall by comparing the forces acting on the wall

Please find the earth pressure at rest distribution value and resultant force on the retaining wall in figure below. The static side pressure coefficient is 0.5.

A retaining wall supports a horizontal backfill that is composed of two types of soil. First layer: 4.27 meters high, Unit weight of 17.25 kN/m3, coefficient of active pressure of 0.286 Second layer: 6.27 meters high, Unit weight of 18.27 kN/m3, coefficient of active pressure of 0.309 Determine the distance of the total active force measured from the bottom of the wall. Round off to three decimal places.
