Content: This open access book summarizes the results of the collaborative project “GeomInt: Geomechanical integrity of host and barrier rocks - experiment, modeling and analysis of discontinuities” within the Program: Geo Research for Sustainability (GEO: N) of the Federal Ministry of Education and Research (BMBF). The use of geosystems as a source of resources, a storage space, for installing underground municipal or traffic infrastructure has become much more intensive and diverse in recent years. Increasing utilization of the geological environment requires careful analyses of the rock–fluid systems as well as assessments of the feasibility, efficiency and environmental impacts of the technologies under consideration. The establishment of safe, economic and ecological operation of underground geosystems requires a comprehensive understanding of the physical, (geo)chemical and microbiological processes on all relevant time and length scales. This understanding can only be deepened on the basis of intensive laboratory and in-situ experiments in conjunction with reliable studies on the modeling and simulation (numerical experiments) of the corresponding multi-physical/chemical processes. The present work provides a unique handbook for experimentalists, modelers, analysts and even decision makers concerning the characterization of various types of host rocks (salt, clay, crystalline formations) for various geotechnical applications

Content: This book is open access book. The collaborative Pilot Project, titled "Comparison of Thermo-Hydro-Mechanical-Chemical (THMC) Processes in Bentonite Barrier Systems", aims to investigate the fundamentals, conduct laboratory and field experiments, and develop numerical models for barrier systems that ensure the safe isolation of radioactive waste in deep geological repositories. This book compares methodologies and technologies used in experimental laboratory and field research, as well as systems analysis, in a collaborative work of German and Chinese scientists. Both parties have access to exceptional experimental and modelling research capabilities. The Beishan underground research laboratory (URL) is currently under construction in Gansu, China. It will serve as an international collaboration platform for URL research in the future. International cooperation is essential for excellent research and development due to the high cost of scientific programmes and technical operation of URLs, making it a precondition for providing secure solutions. This is important not only for deep geological repositories for radioactive waste disposal but also for other geoenergy applications, such as energy storage and geothermal energy utilization.
