The equation that is used to calculate the total shear strength (s) of the material composing a slope, taking account of the pore-water pressure. The shear strength is then equal to the sum of the normal stress (σ) and cohesion (c). The Coulomb–Terzaghi equation is:s = c + σ. helga framework ccsWebThe strength is independent of the normal stress since the response to loading simple increases the pore water pressure and not the effective stress.
