Retaining wall.
A tank of total height 5 m is filled with sand of thickness 3.5 m having void ratio and specific gravity of 0.65 and 2.78, respectively. Remaining portion of tank is filled with water. The pressure head at the bottom of tank is 7.2 m. Assume unit weight of water is 10 kN/m³. The effective stress at a point 3 m below the top of the tank is kPa. (Round off to two decimal places).
The center of a rectangular area at the ground surface has Cartesian coordinates (0, 0), and one corner has coordinates (7, 18). All dimensions are in meters. The area carries a uniform pressure of 135 kPa. Estimate the stresses at a depth of 15 meters below the ground surface at each of the following locations: (0, 0), (0, 18), (7, 0), (7, 18), and (12, 28).a. Obtain the values by the Boussinesq methodb. Compare the results with those of the 2:1 methodc. Comment on the resultsHint: In the Boussinesq method, the equations attached can be used.
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.
