ABSTRACT

ABSTRACT: A permeability model is developed from triaxial flow test data to predict the permeability increase of rock salt around storage caverns, as affected by excavation, confining and internal pressures, age and shape. The confining and internal pressures may increase the surrounding salt permeability from its in-situ value of 10-22 m2 to as high as 10-16 m2. The permeabilities increase with time and reach their ultimate value at within one year after excavation. Salt permeabilities around elliptical caverns are several orders of magnitude higher than those around the spherical cavern.
