(i). Calculate lateral earth pressure for the basement structure. Use the following data, depth of wall 8m, cohesion = 0, angle of friction = 25°, soil type = clay, OCR=2.0, bulk unit weight = 19 kN/m3. (ii)What will change if we would have coarse sand behind the retaining wall instead of clay? Assume compacted coarse sand behind retaining wall and get the recommended values of Cohesion and friction for sand from literature and calculate lateral earth pressure for wall with dimensions given in section (i) and compare both results.

The following concrete gravity wall of 7 m in height retains a sandy backfill. A sand sample from the backfill was brought to the laboratory and tested in a direct shear device under a normal stress of 100 kPa and failure occurred at a shear stress level of 63.4 kPa. Using the Rankine theory, determine the total active earth pressure at the base of the wall when: a) the backfill is dry, b) the backfill is partially submerged in water for a water level at 3.5m from the base of the wall, c) the backfill is fully submerged in water, which means the water table is at the ground surface. Notes: - The saturated unit weight of the soil is 19 kN/m³ -The moist unit weight of the soil is 17 kN/m³ - The dry unit weight of the soil is 15 kN/m³ Summarize your results in this table: b) Total active earth pressure at the base of the wall (kPa)
