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
T 3 m 3 m Ground water table y = 16 kN/m : 30° = c=0 3. Ysat = 18 kN/m Ø = 35° c=0 For the retaining wall shown above calculate the following: A) Calculate the value of K (for either the 'active' or 'passive' earth pressure - whichever is appropriate! ...you decide). B) Calculate and sketch the pressure distribution on the 'back' side (soil side) of the retaining wall (show all of the relevant pressure distributions and indicate the magnitude of the distributions on the sketch). Indicate the correct units! C) Calculate the resultant horizontal force for each pressure distribution and calculate the total overturning moment about the base of the wall. Show the forces in the correct units! D) If this wall has a 'depth' (in-and-out of the 'page') of 20-m, what is the total horizontal force applied to the wall? How much total friction force is needed between the base of the wall and the soil to provide a Factor of Safety of 2.0 against 'sliding'.
7.8 [Use Eq. (7.26).] Figure P7.8 shows an embankment load on a silty clay soil layer. Determine the stress increase at points A, B, and C, which are located at a depth of 5 m below the ground surface.
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
A thin clay layer passes through the soil at an angle of 30° behind an 8m high gravity retaining wall. A structure 5m wide, applying a uniform stress of 40kPa to the sandy soil, also acts on this section of soil as shown in Figure 3.1. The properties of the clay are ??=25???, ∅?=0, ?′=0 and ∅′=20°. The sandy soil properties are ?′=0, ∅′=35°, ????=16??/?2, ????=20??/?2, and between the sand and the wall the properties are ?′?=0 and ∅′?=30°. Assuming that failure occurs along the clay layer, use Coulomb’s method to calculate the horizontal force required from the wall in the short term to prevent slip.
