Question:

Figure P13.3 shows a drilled shaft with bell in a sandy soil. The soil properties are given in the figure.

a. Determine the maximum load that can be allowed on the drilled shaft with a factor of safety of 4. Assume δ' = 0.5ϕ'. Use Eq. (13.18) for Q_p(net).

b. What would be the allowable load if the settlement has to be limited to 15 mm?

Figure P13.3

0.75 m Loose sand y = 17.0 kN/m? o' = 32° 10.0 m 0.75 m 不 Dense sand 1.5 m y = 19.0 kN/m o' = 40° !i!

Eq. (13.18)
