Abstract: A theoretical formula of ettective stress for anisotropic porous media and unsaturated soil isderived on the base of elasticity theory, and the effective stress parameter is measured with convention-al triaxial apparatus. Some misunderstandings on the concept of effective stress are clanfied.
