Creep Damage Evolution of Marble From Acoustic Emission and the Damage Threshold

open access: yesFrontiers in Earth Science, 2020
For the underground engineering, time-dependent behavior (i.e., creep) of rocks is one of the main reasons for instability of surrounding rock in great stress conditions.
