Residual/peak values of cohesion and angle internal friction
Residual/peak values of cohesion and angle internal friction
(OP)
This is probably a simple question... I have soils report that has peak and residual values listed for the cohesion and the internal friction.
Which values would I use for design (e.g. for a retaining wall)?
Thanks!

Many papers on this - I think that Hutchinson (1969 Mexico State of Art Papers for ISSMFE) was a good one. Can also check out (you'll have google):

Rigo (2006) in Canadian geo Journal "Residual strength of Tropical soils"
Stark (1994) in ASCE GT Journal "Drained Residual Strength of Cohesive Soils".
Sorry I can't give out the URL's on the later.
