Limit of Skin Frictions

QUESTION
I am trying to gather information about the maximum unit skin friction for piles:

  • Prakash and Sharma (1990)suggested fs<=1 tsf. I also read somewhere that fs should stop increasing from 10D~20D depth.

  • Bowles (1996) only says that fs should be considered but didn’t say how.

  • Coduto (2001) didn’t mention limiting fs at all.

Any more reference on this topic?
