Friction Angle Correlations
Friction Angle Correlations
(OP)
Is anyone aware of a published correlation that relates friction angle to a percent compaction for a predominantley granular soil. If there is something out there I would think it would be specific to a range of gradation.

It shows, for example, phi' for SW ranging from 27 deg at RD=0, to 37 at RD=75, to 41 at RD=100. Believe the trend, but not the specifics, since it's all dependent on coeff of uniformity, particle angularity...
Presumably these are peak rather than phi-cv, which I would expect to be more nearly constant with RD.
