Introduction and Abstract
It is projected by the German governement to deposit radioactive waste in a great salt dome in northern Germany (Lower saxonia). Because of the necessity of guaranteeing the safety of the repository over long lasting periods of time, a very good knowledge of the behaviour of the used materials, especially the host rock salt and the probable backfilling, crushed salt, is indespensible. This is seen to be a basis of technical security calculations in underground dam constructions, backfilling and the behaviour of the host rock. An extended paper of our former research on this field has been presented in [SWM87]. The presented theory is founded on basic physical mechanisms of dislocations and developed to equations describing dislocation multiplication and annihilation. From these a complete theory of transient creep in rock salt can be deduced which is compared with experimental results and shows very good agreement.
