Development and applications of the quasi‐dynamic triaxial apparatus for deep rocks

open access: yesDeep Underground Science and Engineering, Volume 3, Issue 1, Page 70-90, March 2024.
Two modifications were made to the TFD‐2000/D rock triaxial instrument to achieve the rock in fatigue creep alternation, variable amplitude cyclic disturbance, and constant fatigue loading on rocks. After the test, it could be well adapted for the study of strong disturbance and timing‐dependent properties of deep rocks.
