To address this critical issue, this paper systematically reviews the research progress concerning the disaster mechanism of tunnel surrounding rock collapse. Specifically, the review elucidates the main causes and various types of tunnel collapse. Furthermore, the application and limitations of different research methodologies-including model tests, numerical simulations, and theoretical analyses in revealing the disaster mechanism of tunnel surrounding rock collapse are critically discussed. Based on this analysis, potential future development trends in the field are proposed.
