Erhohung der Wirtschaftlichkeit von Speicherkavernen durch Anwendung eines neuen Entwurfs-und Nachweiskoneptes (I)

摘要

The major elements of a dimensioning concept for the design of storage caverns are the used material model and the proof criteria with their limits and safety margins. A main characteristic of a material model based on Continuum Damage Mechanics (CDM) is the qualitative integration of the structural damage prior to material failure into the numerical simulation of the bearing behaviour.
