THE EFFECT OF SMALL DEVIATORIC STRESSES ON CAVERN CREEP BEHAVIOR

摘要：

One-year-long creep tests performed under very small deviatoric stresses and a 6-month-long brine outflow test performed in a shallow salt cavern are described. Both strongly suggest that the rate of salt creep under small deviatoric stresses (σ<5 MPa ) is likely to be much faster thanwhat usually is inferred from laboratory tests performed under higher mechanical loadings. Numerical computations prove that cavern-closure prediction has potential significant consequences.
