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

Highlights

• The development of the dynamic rock mechanics instrument is clarified, and the three major shortcomings of the existing instruments are summarized.

• Based on the conventional triaxial instrument, the first generation of the TFD-2000/D triaxial instrument was developed, which can apply disturbing load independently, implementing the function of cyclic disturbance and combined dynamic and static disturbances.

• The second generation of the TFD-2000/D triaxial instrument is improved to achieve variable amplitude cyclic loading, low-frequency high-level ground stress loading, and cyclic dynamic disturbance alternating with creep.
