Q3. 3 m 2 m 16 m Consider a 750 mm diameter bored pile to be installed in soil layers with a profile as shown in Figure Q3. Assuming the pile will settle sufficiently upon application of load so that both the shaft friction and end bearing will be mobilized, calculate; a) the ultimate load capacity Qu of the pile (12 marks) b) the total shaft friction Q, in the 5 m sand layer if the ground water table is located 1 m above the ground surface (8 marks) c) the allowable uplift capacity if a reduction factor RF = 0.6 is applicable to shaft friction assuming the unit weight of concrete Yeone = 24 kN/m³.
