Abstract To study the dynamic mechanical properties of tuff under different environmental conditions, the tuff from an
ancient quarry in Shepan Island was prepared. The impact damage to the rock was tested using a triaxial dynamic
impact mechanical testing system (TDIMTS) with different ground stresses, temperatures, and groundwater pressures. The time-strain relationship, dynamic stress-strain relationship, energy dissipation law, energy-peak strain
relationship, and the impact damage pattern of the tuff specimens under impact air pressures were investigated.
The TDIMTS experiment on ancient underground rock mass under impact loading was also simulated using the
finite element analysis software… More >
