    Abstract
  • To assess the effect of cyclic explosion on underground caverns, based on a similarity model test, the finite element software ABAQUS was utilized to analyze the dynamic responses and cumulative damage of underground caverns under cyclic explosion at low levels and a single explosion at high level. The stress wave attenuation characteristics and the cumulative damage evolution laws of the surrounding rock were presented. Besides, the displacement of the vault and the circumferential strain of the cavern wall were compared and analyzed. The results indicate that, with the increase of explosion times, the stress wave attenuation speed of the surrounding rock under cyclic explosion decreases first and then increases. In the single explosion, the peak circumferential strain of the cavern walls changes from tensile strain to compressive strain from the vault to corner. In the cyclic explosion, the peak circumferential strain of the vault changes with the increase of explosion times from compressive strain to tensile strain. Under the same explosion loading in total, the damage of the surrounding rock is greater in the low-level cyclic explosion than that in the high-level single explosion in terms of area and degree. In addition, the cumulative damage of surrounding rock under cyclic explosion presents an irreversible and step-by-step increase, and shows a dramatic nonlinear relationship with explosion times.
