(c) Consider the soil profile and arrangement of piles as shown in Figure Q3(c). A group of 5 cast in-situ bored concrete piles with a diameter of 450 mm and 15 m long are proposed to be installed in those sand deposits. Determine the ultimate compressive load that can be supported by the pile group assuming the base of pile cap is at the ground surface. Use effective depth of pile L' = 15D where necessary. Note that the ground water level is at 5 m below the ground surface. 5 m 15 m DR S Loose SAND y = 16 kN/m³, -30° N₁* = 55,8=0.86 Medium dense SAND Ysat 18 kN/m³, ' = 33° N₁100, 80.76 O O Note: s= 1350 mm center-to-center Figure Q3(c)
