Finite element analyses are being used for the design of mines or caverns in salt deposits, which are to be used as repositories. A review is given of an effort to construct adequate constitutive equations for the creep of natural rock salt at relatively low temperatures, low stresses and for long times. Starting with laboratory creep test data, the construction of creep laws is described. These are extended to constitutive equations for arbitrary stress states and histories by means of viscous and elastic-viscous theories. Predictions using them are compared with each other and with actual mine closure data. 15 figures.
