| Résumé | Ice was used as an analog for rock to simulate cracking behaviour during unloading. Columnar grained ice samples were pressurized and then brought to the melting temperature to cause melting at the grain boundaries, thereby removing any intergranular stress. Then, while pressurized, the samples were allowed to refreeze. Then pressure was rapidly removed. No cracks were observed, in contrast to previous experiments on granular ice samples where air was present at grain boundaries. This suggests that air plays an important role in producing cracks. Compressive strength tests performed immediately after depressurization showed no correlation between strength and degrees of stress drop at depressurization. |
