A smooth, vertical wall is 18 feet high and retains a cohesionless soil with a unit weight of 125 PCF and a friction angle ( t) of 32 The top of the soil is level with the top of the wall and the soil surface carries a uniformly distributed load of 1,200 PSF Use Rankine theory to calculate the total active earth pressure on the wall per linear foot of wall and the location of the active earth pressure.
What all factors an engineer must consider for designing a retaining wall to retain a soil of height 10m? How those factors are different for a cohesionless soil, a cohesive soil and a saturated soil?

Determine the distribution of horizontal stresses on the wall and the magnitude of resultant thrust when water table is at 3 m below the ground surface Determine the magnitude of resultant thrust when the water table is well below the base of the wall Determine...
Figure 15.45 shows a gravity retaining wall retaining a granular (c' = 0) backfill. The same soil is present at the bottom of the wall and on the left. The unit weight and the friction angle of the backfill are 18.5 kN/m3 and 35°, respectively. The unit weight of concrete is 24.0 kN/m3. Determine the factors of safety with respect to overturning, sliding, and bearing capacity failure. Use Rankine earth pressure theory.
A 12 m high retaining wa is built to retain a 3-layered soil profile shown in Figure 2. The soil parameters are given in the figure. During raining season, ground water rises to interface between Soil 1 and Soil 2. Assume that there is no friction between the vertical wall and the soils. (i) Find the surface surcharge q that would just close the tensile crack on the ground surface at the active failure stage of the retaining wall. (5...
A 4m high, vertical retaining wall supports Silty SAND backfill with a horizontal surface. There is a hydrostatic horizontal water table at 1 m below the ground surface. The soil has bulk unit weight = 20 kN/m3, effective cohesion=5 kPa, and friction angle= 30o. What is the value of the water force on the wall? At what distance above the base of the wall does it act?
You have to review the design of a cantilevered concrete retaining wall designed for the height and soil as shown in the figure. Please check the design and provide your recommendation for the following situation: - 200 psf Surcharge load on top of the backfill material Lean clay at foundation same soil for backfill Dry unit weight of soil Cohesion/adhesion of the clay/concrete Bearing capacity of the soil Active earth pressure coefficient Ignore the effect of ground water table Unit...
a) A cantilever retaining wall is constructed to retain the earth in order to create a change of elevation. The stability aspect of a retaining wall is important to prevent any failure of the structure. Referring to Figure 2, check the stability of the cantilever retaining wall against: (i) Sliding (ii) Rotation (ii) Bearing failure (iv) Short conclusion on the stability of the wall [5 marks] [4 marks] [3 marks [2 marks] 0.5 m 4.0 m 0.8 m 1.2 m...
