The first layer is 4.47m high. It has a unit weight of 16.92kN/m3. The second layer is 5.76m and has a unit weight of18.51 kn/m3. If the angle of friction for both layers is 38 degrees, determine the total active force (kN) acting on the retaining wall per unit. Use stored value. Asnwer on 5 decimal places.You are working for a consulting firm that has been asked to evaluate the factor of safety of the wall shown in the figure supported by a well-degraded sand.

- The following figure shows a section of an anchored retaining wall embedded into a saturated stiff clay layer. The sand has a unit weight of = 18 kN/m³, c' = 0 kPa and o' = 34º. The clay has a unit weight of = 20 kN/m³, c₁ = 80 kPa and = 0°. A uniform pressure of 40 kPa is applied on the soil surface. The short term stability of the wall is considered in an undrained analysis. Use the Rankin's theory of lateral earth pressure to determine the active and passive horizontal stresses. You should apply the requirements of AS 4678 and the partial factors of safety method in estimation of soil pressures.
