“…To simulate the field F-T condition for rock, F-T test is usually to be used to mimic the natural weathering of rock under low temperature at a faster place in the laboratory. The impacts of rock mineral composition, rock porosity, F-T cycle number, freeze temperature, F-T solution, etc., on rock mechanical properties have performed systematic research, and corresponding damage models have been proposed to describe the F-T fatigue damage, mainly including the uniaxial compressive strength (UCS), elastic modulus, porosity, P-or S-velocities, and mass loss rate [3,[6][7][8]. Nowadays, plenty of devotions have also been done to investigate the F-T mechanical and physical properties of various kinds rock, such as dolomitic limestone [9], oil shale [10], diorite [11], tuff [12], sandstone [13,14], granite [15], coal [16], mudstone [17], sandy mudstone [18], and slate [19] from various cold regions in China using various F-T laboratory tests.…”

“…Acoustic emission (AE) source localization, as an important non-destructive testing technology, is widely used to study material failure mechanism and predict the position of potential hazards [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 ]. There are many traditional positioning methods, including Taylor-based methods [ 11 ], Inglada method [ 12 ], spherical-interpolation method [ 13 ], spherical-intersection method [ 14 ], and plane-intersection method [ 15 ].…”

“…They found that the rock elastic parameter of Poisson's ratio and elastic modulus and the equivalent volume expansion coefficient of water-ice medium influenced the frost heaving force. Wang et al [17] measured the frost heaving force in preflawed granite and found that F-T damage increased with the F-T cycle, and the FHF decreases with increasing the F-T cycle. Plenty of experimental methods have been conducted on flawed or notched rock subjected to freeze-thaw treatment, and the potential FHF was obtained.…”
