Dear Friends,
I have the following theoretical doubt and maybe I am doing a stupid question: let you suppose that by means of triaxial CU tests the effective shear strength parameters (c' & phi') of a saturated clay have been derived. Could I derive from the effective envelope the undrained...
Dear Friends,
I have some doubt about the definition of the effective stress proposed by Terzaghi and reported in the book Underground Excavation in Rock (Hoek & Brown, 1980):
s'=s-(1-nb)u
where s'=effective stress; s=total stress; u=pore pressure and nb=boundary porosity.
Evidently the formula...
Hi,
it is not clear to me why it is suggested to derive the Young modulus (Ey) from the pressumeter (Menard) modulus (Em) by dividing the latter by one reological coefficient (alfa). My question arises from the fact that Em is already calculated considering only the elastic deformation occurred...
