THREE EFFECTIVE STRESS THEOREMS FOR THE VOLUMETRIC RESPONSE OF THE SATURATED PORELASTIC MEDIA WITH DOUBLE POROSITIES

摘要：

Based on the hypothesis that both porous media and solid material behave linear elasticity,the effective stress theorems of the porous media with double porosities are investigated.First,the general bulk responses of the saturated porous media independent of the pores and fissures geometry are derived analytically by using three theorems in elastics.If the spherical cavities and narrow cracks are used to model respectively pores and fissures,the four effective stress theorems for the bulk responses are derived analytically.
