Refer to the pipe pile in saturated clay shown in Figure 1. For the pile,

Calculate the skin resistance (Qs) by (1) the α method, (2) the λ method, and (3) the β method. For the β method, use ϕ’_R= 30⁰for all clay layers. The top 10 m of clay is normally consolidated.The bottom clay layer has an OCR = 2. (Note: diameter of pile = 457 mm)
Using the results of Exercise 10, estimate the allowable pile capacity (Q_all). Use FS = 4
