Rankine Earth Pressure theory	Coulomb's Earth Pressure Theory
In this,rankine's considered real,frictionless face of retaining wall which is in contact with backfill.	In this,Coulomb considered a retaining wall with friction.
Here retaining wall is only vertical	It may be vertical,or inclined or both.
In this theory,elemental failure is considered.	Here wedge failure is considered.
We can find both active and passive earth pressure.	It is not suitable for passive stage.
This is related to plastic equilibrium	This is related to elastic  equilibrium.
