Mechanical Behaviour of Salt VII

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.
