STUDYING COUPLED EFFECTS IN THE EXCAVATION DISTURBED ZONE (EDZ)FOR A CRYSTALLINE ROCK: THE WORK OF DECOVALEX-THMC TASK B
The overall DECOVALEX-THMC project is taking place in the period March 2004 to September 2007 with the intention of improving the capability of thermo-hydro-mechanical-chemical models to support the design of radioactive waste repositories and the associated safety analysis. The specific objective of Task B, one of the DECOVALEX-THMC tasks, is to improve understanding of the evolution of the EDZ and to be able to numerically model the EDZ HMC mechanisms in a fractured crystalline rock mass. This paper describes the Task B EDZ work currently underway and summarises the results to date. Particular progress has been made on the numerical modelling of rock specimens loaded in uniaxial compression and the mapping of the EDZ at the Aspo HRL APSE tunnel. Several companion papers being presented at the GeoProc2006 Conference are referenced because they explain various facets of the Task B work in more detail.
