A static pile load test using an O-cell was carried out on a 1.8-m-diameter, 25-m-long (embedded length) drilled shaft. The soil profile is as given in Table P13.3a (the negative sign means below ground surface). Selected load-displacement data are shown in Table P13.3b.

(a) Make a neat sketch of the soil profile and the drilled shaft, as shown in Example 13.3.

(b) Determine the ultimate skin friction and ultimate end bearing capacity.

(c) If an FS of 2 is required, determine the allowable load and settlement. Justify your answers.
