Microcracking and stress - Strain response of thermally loaded granitic rock: in situ and laboratory experiments

Original language description

The results obtained in the project FR-TI3/325 - Research on a thermally loaded rock - perspectives of underground thermal energy storage are presented in this paper. The project was designed to study thermal energy flow in granitic rock (tonalite), both in terms of efficiency as well as safety. The results include in-situ and laboratory thermal experiments. In the frame of an in-situ experiment, a study of thermal stress was carried out in the underground laboratory Josef in Czech Republic. Stress changes in rock environment induced by cyclic thermal loading at 120 m depth were continuously monitored in order to evaluate the influence of the thermal load increments. Tonalite cores were subsequently tested in laboratory. Cylindrical samples were heated in servo-hydraulic loading frame to obtain the stress response and monitor acoustic emission activity. A detailed P-wave ultrasonic sounding on spherical samples was used to evaluate the extent of heating induced damage.
