I have heard a number of rules of thumb for estimating the depth to the bottom of a general shear failure surface. Anwhere for 2B to 4B for cohesionless soils, and around B for cohesive soils.
I can't seem to find any document that talks about this. Could somone point me in the right direction? Thanks.
