Application of Flac2D to the Temperature Calculation and Approximate Damage Analysis for the Canister Retrieval Test in Sweden
During the period from October 2000 to November 2005, the canister in the CRT deposition hole DD0092G01 was heated with a maximum heat power of 2600W and the temperature and consequently the stress in the surrounding rock volume were elevated. This study investigated if the temperature and possible heat induced damage can be predicted by 2-Dimensional numerical simulations. FLAC2D(5.00) was used to model the excavation and the heating process of the deposition hole. Temperature in the rock was calculated by treating the case either as a horizontal two dimensional or a vertical axisymmetric problem and obtained results were compared with the measured results, whereas stress was calculated from horizontal two dimensional thermal-mechanical coupling analysis and calculated results were applied to approximate damage analysis.
