... cavern, and the ground subsidence were simulated employing an elasto-viscoplastic damage constitutive equation for rock salt. The results indicate that the damage and failure zones propagate much larger in the mudstone interlayer than in the host salt. The volume of damage and failure zones surrounding...

... rather than bedded salt formations as host rocks, while in China, salt domes suitable for energy storage have been hardly found so far. Bedded salt rocks are usually composed of many thin salt layers and non-salt sedimentary interlayers (e.g. anhydrite, shale, dolomite, glauberite, etc.) (Li et al. 2007a...
