Hi David,
First comes to mind is the summary report by Prof. Aleksandar Vesic to
Transportation Research Board [1977, NCHRP Report 42, Design of Pile
Foundations]. Reference to Figure 30 shows Mindlin solution for vertical
stress distributions for the shaft and point components. These 2 charts
apparently taken from Grillo, O. (1948, 2nd ICSMFE, Rotterdam).
Another would be the Boundary Element solutions given in Chapter 5 in the
Poulos & Davis (1980) book [Pile Foundation Analysis & Design], originally
published by Wiley & Sons, but re-issued by R.E. Krieger Publ. Co., Krieger
Drive, Malabar, Florida 32950 USA in 1990.
Finally, an approx. solution is given by Randolph & Wroth (1978, ASCE
Journal of Geot. Engrg. Div. 104, No. GT12) and (1979, ASTM Spec. Tech Pub.
670) that is easily programmed on a spreadsheet.
As far as the documentation, wow! That's another email reply later.
Sincerely,
Paul W. Mayne
