Abstract:
|
Deep geological disposal in suitable host rocks is the favoured strategy for the
storage and disposal of heat-emitting high level nuclear waste. A rational design of
repositories requires a good understanding of the interacting thermo-hydro-mechanical
phenomena that occur in the engineered barrier and adjacent rock. To this end, a
multiphysical formulation is described that allows the performance of coupled THM analyses capable of reproducing observed phenomena. The formulation and computer code is applied to the simulation of two large scale tests: a mine-by test involving the excavation of a shaft in an argillaceous rock and a large-scale high- temperature heating test in fractured rock. |
