Study on critical slowdown characteristics and early warning model of damage evolution of sandstone under freeze–thaw cycles

Freeze–thaw damage of rock mass poses a great threat to the safety of rock engineering, ground buildings, and low-temperature storage of liquefied natural gas (LNG) in cold regions. By collecting acoustic emission (AE) signals of sandstone during uniaxial compression failures, this paper analyzed th...
