 Abstract:             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
