内容記述 | The concept of storage coefficient was discussed based on the theory of poroelasticity. Several different storage coefficients can be defined by different mechanical boundary conditions and assumptions on the physical properties of constitutive materials. The specific storage, which is usually used in the field of hydrogeology, is shown to be defined when the representative elementary volume is maintained in a state of zero lateral strain and constant stress perpendicular to that plane. This means that the specific storage is not measured in most laboratory pore pressure tests because the boundary condition of zero lateral strain is not satisfied. Instead, we measure a three-dimensional storage coefficient. In the latter sections of this paper, we present a new method to determine both the hydraulic conductivity and the storage coefficient through simultaneous measurements of fluid pressure and strains. In this study, a new endplug with a built-in valve was developed to accurately measure the poroelastic parameters. Our experimental assembly significantly reduces the extra volume of the system and is readily adapted to the various pore-fluid boundary conditions. The three-dimensional storage coefficient was calculated from the volumetric poroelastic parameters obtained from quasi-static strain data, and the hydraulic conductivity from the transient pore pressure diffusion data. Transient strain behavior during the pore pressure diffusion stage was used to self-check the accuracy of the parameters obtained. This technique does not require complicated inversion calculations and can be used easily for parameter identification. | |||||
