The following concrete gravity wall of 7 m in height retains a sandy backfill. A sand sample from the backfill was brought to the laboratory and tested in a direct shear device under a normal stress of 100 kPa and failure occurred at a shear stress level of 63.4 kPa. Using the Rankine theory, determine the total active earth pressure at the base of the wall when: a) the backfill is dry, b) the backfill is partially submerged in water for a water level at 3.5m from the base of the wall, c) the backfill is fully submerged in water, which means the water table is at the ground surface. Notes: - The saturated unit weight of the soil is 19 kN/m³ -The moist unit weight of the soil is 17 kN/m³ - The dry unit weight of the soil is 15 kN/m³ Summarize your results in this table: b) Total active earth pressure at the base of the wall (kPa)
Question 1: You are designing a retaining wall at the construction site. The friction angle of sand backfill is 28". Define the active lateral earth pressure coefficient based on Rankine's theory. Show your work and select the closest value: a) 0.30 b) 0.35 c) 0.40 d) 0.50
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.
