Water saturation dependent acoustic emission event structures and damage accumulation paths in limestone with a central circular through hole

The instability of holed limestone in water-rich karst areas is controlled by both hole-induced stress concentration and water-induced weakening. Its damage evolution is reflected not only by mechanical degradation, but also by changes in acoustic emission event structures and energy release paths. To clarify the dam...
