The fundamental governing equation for the transient flow in homogeneous and isotropic poroelasticity has been used to obtain the permeability and storage coefficient of specimen under axi-symmetric triaxial stress state. Rigorous analytical solutions of Constant Head, Falling Head, Transient Pulse and Constant Flow Pump Tests are presented. They were also adopted to compare the distributions of hydraulic head and hydraulic gradient within the specimen among the four permeability tests. It was found that the time-dependent variations of hydraulic head and hydraulic gradient within specimen are rather complicated. Three dimensional storage coefficient (S') of homogeneous porous media is greater than the specific storage (S). Special attention should be paid when estimating the storage coefficients because different storage coefficients are defined by different boundary conditions based on the poroelasticity.
