The research progresses on several important issues in the study of earthquake power catastrophe in large underground caverns are summarized, including four aspects: classification of catastrophic catastrophic modes of large underground caverns, identification of catastrophic catastrophic factors of earthquake power, existing seismic response Brief introduction of analytical methods, and the progress of simulation and control methods of earthquake power catastrophe process. Based on the review of the existing research results, the problems to be solved and the future development directions are pointed out, including the seismic monitoring of large underground caverns, the indoor model test and the observation of on-site prototype dynamic characteristics, the earthquake of large-scale underground caverns Input mechanism, dynamic constitutive model of rock mass under earthquake, seismic disaster catastrophe criterion of large-scale underground caverns, control measures of large-scale underground cavern group earthquake catastrophe, consensus and standardization of research results. I hope this article can provide some reference and basis for future related work.
