Question

A driven closed-ended pile, circular in cross section, is shown in Figure P 9.4.
Calculate the following.
a. The ultimate point load using Meyerhof’s procedure.
b. The ultimate point load using Vesic’s procedure. Take I_rr = 50.
c. An approximate ultimate point load on the basis of parts (a) and (b).
d. The ultimate frictional resistance Q_s. [Use Eqs. (9.40 (L' ≈ 15 D)) through (9.42), and take K = 1.4 and ẟ' = 0.6 Φ'.]
e. The allowable load of the pile (use FS = 4).
