This collection of papers on research into and management of underground structures in salt formations represents the state-of-the-art on applications of salt mechanics in mines and storage caverns for gas/hydrocarbon, radioactive waste and toxic waste disposal. The contributions cover laboratory experiments, constitutive numerical modeling and field investigations, and deal with creep, damage, thermo-hydro-mechanical and chemical-coupled effects, lessons learnt from real sites and structures and in-situ monitoring. The book is organized into eight topics:
Laboratory investigations and constitutive modeling
Coupled processes and hydro-chemical effects (THMC)
Field measurements and back-analyses
Numerical modeling
Dry mining, post-mining and backfilling
Liquid hydrocarbon storage and brine-production caverns
Gaseous hydrocarbon storage and compressed air energy storage
Hazardous and radioactive waste disposal
Mechanical Behavior of Salt VII will appeal to academics, engineers and professionals involved in salt mechanics.
