The DECOVALEX Coupled Modelling Project: Past, Present and Future
The construction of facilities on and in rock masses requires an understanding of rock mass behaviour so that the effects of excavation and support can be predicted with the necessary accuracy for design purposes. The DECOVALEX Project (Demonstration of Coupled Models and their VALidation against Experiment) aims at developing the appropriate characterisation and modelling capability in the context of radioactive waste repository design plus the associated performance and safety assessments. The DECOVALEX Project has been in operation since 1992 with an international collaboration of waste management organizations and regulatory authorities supporting research teams from Canada, China, Czech Republic, Finland, France, Japan, Germany, Korea, Spain, Sweden, UK, and USA. In this paper, we summarise the coupled modelling advances made in the previous DECOVALEX phases (Phases I, II, III and THMC) and describe the current DECOVALEX-2011 work on modelling (a) the ventilation experiment at the Mont Terri Underground Laboratory in Switzerland, (b) the pillar stability experiment conducted at the (A)sp(o) Hard Rock Laboratory in Sweden, and (c) the hydro-mechanical-chemical interactions for single fractures and fracture networks. The DECOVALEX Project has firm plans until 2011 when the results will be disseminated at the time of the ISRM Congress in Beijing.
