(b) The variation of N60​ with depth in a granular soil deposit is as shown in Table Q1(b). A rectangular concrete pile 7.5 m long (0.5 m×0.5 m in cross section) is driven into the sand and fully embedded in the soil. For the proposed site, given: Design load = 1112.1kN,FOS=3.0,Pa​=100kN/m2 and Lpile ​=7.5 m. (i) Design Qp​ by using data given in Table Q1 (b) (6 marks) (ii) Design Qs​ by using data given in Table Q1(b) ( 5 marks) (iii) Estimate the allowable bearing capacity Qall​ of the pile (3 marks) (iv) Predict the elastic settlement of the pile based on the situation.
