Assume a smooth retaining wall as shown below. Calculate the active force due to the earth pressure only 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
Q: The following figure shows a soil system supported by a 3m high retaining wall. This is normally consolidated soil and the wall has been restrained from yielding. Determine the lateral force Po, exerted by the soil system on per unit length of wall. [Yw = 9.81 kN/m³] H = 3m A B С c'=0 $ 20⁰ y = 15 kN/m 3 c'=0 Ø Y sat 20° 18 kN/m3 2m
An 8 m tall retaining wall holds cohesionless sand with a density and angle of internal friction of 1.85 Mg/m3 and 33°, respectively. If the surface of the backfill slopes upwards at 86° to the vertical, Use Rankine’s conditions to find the force per unit length of the wall and its location for (a) Active State (b) Passive State Please draw the pressure diagram neatly for both cases
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
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.
