I work in a UK independent soils laboratory and often receive samples from clients that want permeability, UU triaxial or shearbox tests, but the client fails to supply the effective stress details. When asked the pressures to be applied to the samples, they often don't even know they are required to specify them, let alone what they should be.
I wonder if anyone knows where I can find a published method of calculating overburden pressure and effective stress from the sample depth and can point me to a document I can use.
