Abstract

Abstract

Dynamic experiments on skarn were conducted with a modified one-dimensional coupled static and dynamic loads based on SHPB device. The variations of dynamic deformation modulus of skarn under different axial pressures and frequent dynamic disturbance are studied when confining pressure was unloaded at the 1 MPa/s rate to 50% of initial value. The results show that high axial pressure promotes the formation and propagation of microcracks in rocks and reduces the resisting ability under external shocks. The lateral restraint of confining pressure hinders the transverse propagation of cracks inside the rock, but it will aggravate the damage when confining pressure is unloaded. This is because, under high axial pressure, unloading of confining pressure results in redistribution of stress inside rock. The axial pressure and confining unloading pressure affect the dynamic deformation modulus of rock under impact. Base on the variation analysis of dynamic deformation modulus by the energy dissipation of rock under impact, some significant understanding of deep rock excavation failure mechanism are drawn.
- frequent impact,
- dynamic deformation modulus,
- confining pressure unloading,
- energy dissipation
