Experimental evaluation of multiscale damage evolution in fissured limestone under different wet-dry cycles and axial stress.
Fissured limestone in the gorge-section hydro-fluctuation belt of the Three Gorges Reservoir (TGR) is continuously affected by wet-dry cycles and overburden self-weight stress, and its progressive deterioration markedly increases geohazard risk. However, the multiscale damage evolution mechanism of fissured limestone i...
