Rankine vs Coulomb Failure envelope
Rankine vs Coulomb Failure envelope
(OP)
As for the Rankine method (where the active failure plane behind the wall = 45+phi/2), can someone please explain to me (or at least point me in the right direction) how you would derive the failure plane angle for the Coulomb method?

You should be able to find one on internet. It is a monster formula.
If you wanted to "derive" it then have fun with math.
