摘要：

Poroelastic and hydraulic parameters of sedimentary rocks were estimated simultaneously from triaxial compression tests with instantaneous change of axial stress, confining pressure, or pore pressure. In terms of hydraulic constants, those from triaxial tests agreed well with those from transient pulse permeability tests. The experimental results for discharges from the specimen during the tests permit theoretical interpretations. Therefore, besides the behavior of pore water, the transient response of rock deformation corresponding to pore water movement can be theoretically treated. Accordingly hydraulic constants can be estimated from the strain data of triaxial tests with instantaneous change of stress or pore pressure.
