Numerical modeling of interactions between crushed and intact salt
The results of several analyses studying the interaction between intact salt and crushed salt in realistic field configurations, such as backfilled shafts and drifts, will be presented. The analyses use a volumetric creep model for wet crushed salt and an elastic-secondary creep model for the deviatoric behavior of intact salt. The material parameters for the wet crushed salt model are derived from hydrostatic consolidation tests performed on wet salt by Holcomb. The calculations show that the wet crushed salt does not significantly retard the rate of closure of shafts and drifts until the crushed salt is consolidated approximately 95% of intact salt density. The importance of the crushed salt deviatoric will be discussed. 9 refs., 24 figs.
