Abstract  Based on the system research data at home and abroad, the rock mass structure information collection and integration, dangerous rock stability reliability analysis, rock collapse disaster monitoring and prevention were summarized and researched, in order to analyze the current research status of the tunnel rock collapse disasters. Combined with the research work, the theory and technical defects of rock collapse disaster were summarized, and the relevant prevention and control measures against dangerous rock fall were also analyzed, so as to provide theory basics for dangerous rock collapse during tunnel construction.
