A retaining wall with a smooth vertical back retains silt backfill for a depth of 6 m. The backfill has a horizontal surface having following properties c'= 10 kPa, = 20° and y = 17 kN/m³. Calculate the percentage decrement in the magnitude of thrust on the wall when the wall is restrained against yielding to when the wall is free to yield (assume development of tension crack when wall yields). A 32.8% B 45.7% C 50.3% D 61.4%
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
3. Compute the resultant lateral force for the soil-wall system shown in Figure 3. You may ignore tensile cracks. Use • A- Coloumb • B - Rankine 0=30°, y=20kN/m³ 4m Ground water table 7m c=50KN/m², p=10°, y=18KN/m³ 0=25°, y=20KN/m³ 8 m Gravity wall Figure 3
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. Assume the soil is in-situ and use a structural classification factor of ₁ = 1. 3m 1m Water table 1.5m 40 kPa Not to Scale Sand Clay Ta
Assume a smooth retaining wall as shown below. Calculate the hydrostatic force acting on the right side of the wall in kN per unit length (considering a 1 m length in the out-of-plane direction). The soil properties shown in the figure apply to either side of the wall g = 9.81m/s2
