Chapter 12, Problem 12.5P
A 400 mm × 400 mm square precast concrete pile of 15 m length is driven into a sand where γ = 18.0 kN/m3 and ϕ′ = 33º. Assuming δ′ = 0.7ϕ′ and K = 1.4 Ko, determine the load-carrying capacity of the pile with a factor of safety of 3. Use Meyerhof’s method [Eq. (12.18)] for computing the point load-carrying capacity Qp, and Eqs. (12.42) and (12.43) for computing the load-carrying capacity of the pile shaft Qs.

To determine the elevation of a point such as B in Fig. 24 in the text, the following procedure was used: With the transit set up over a point such as A whose elevation is 128.3 ft, the height of the transverse axis above A was 4.84 ft and the vertical angle b between the horizontal line CD through the transverse axis and the line of sight to the point B was +12º 42'. Then a point such as E was marked on the ground on the line between A and B and at a horizontal distance from A equal to 50.00 ft. Finally, with the transit set up over the point E, the difference in elevation between the point A and the transverse axis F of the transit at E was found to be 3.47 ft, and the vertical angle d between the horizontal line through F and the line of sight to the point B was +18º 07'. The elevation of the point B is
