Abstract

Ultrasonic monitoring is used to characterize the damaged zone in the host rock around the PRACLAY gallery. This investigation uses an inversion technique to analyze changes in transmission velocity based on the non-interactive crack effective medium theory. This paper presents the first monitoring results that show the evolution of the EDZ following the excavation of the PRACLAY gallery and before the thermal load experiment begins. In general, all monitored regions around the gallery EDZ show limited cracking, with no connectivity.
