Explain earth pressure at rest. The retaining wall used to support the underpass at BRT Peshawar University section is retaining 22 feet of soil on its back. If the soil properties are C=0, φ = 35 degrees, γ = 130 lb/ft3, and the water table is below the wall then what will be soil pressure on the section with roof slab and the approach ramp where there is no top slab? Compare the results and discuss what type of pressure is expected in each section. (Only provide results and discussion on how you calculated the result.
