Abstract：
Although there have been abundant research achievements regarding rock bursts in the Guanshanling tunnel, this phenomenon is still a worldwide problem. Based on the cases of the Gaogaishan tunnel and the Jinguashan tunnel on the Xiangtang-Putian railway, the features, classification, influential factors, and prediction of rock bursts in tunnel engineering were analyzed by means of the criteria for and classification of rock bursts in foreign countries. This paper presents preventive measures, including the drilling of holes for stress release, water injection, and anchoring. Meanwhile, it discusses opinions and suggestions concerning the criterion, classification, and prevention of rock bursts and emphasizes the importance of comprehensive criteria for studying rock bursts.
