Abstract

The aim of the TIMODAZ project is to investigate the effect of thermal changes on the excavated damaged zone (EDZ) around nuclear deep disposals in clay host rocks. During the disposal construction, rock mass around the gallery is damaged and its permeability may be modified. Further the drainage and later the heating will modified the size and the structure of the damage zone. In the framework of the TIMODAZ project, it is intended to develop constitutive models and numerical tools. A series of benchmark modelling with different constitutive laws and numerical tools are performed. From now, two benchmarks have started. The first one concerns a small scale laboratory experiment on a hollow cylinder clay sample submitted to thermo-hydro-mechanical loadings. The second one is an in-situ experiment which studies the water transmissivity evolution trough the EDZ.
