摘要：
The freeze-thaw (F-T) damage characteristics of anchored fractured rock masses are different from those of fractured rock masses without bolts. To explore the F-T damage location and characterize zonal damage of anchored rock masses, two stages of F-T cycle tests were conducted for the samples with no bolt, 45 degrees bolt and 90 degrees bolt respectively. CT scan tests were performed before and after F-T cycling. Visual damage was qualitatively evaluated through 3D image reconstruction of CT data. The zonal damage characteristics of the samples were quantitatively analyzed using 2-d CT slices...
