| 英文摘要 | Due to the large buried depth and active geological structure, dynamic disasters such as rockburst posed a severe threat to the Sichuan-Tibet railway tunnel's safety during construction. The prediction and prevention of rockburst has become a major research topic in the Sichuan-Tibet railway tunnel engineering community. Recent studies on rockburst propose numerous numerical simulation methods. These methods are based on static and quantitative calculations to make a qualitative assessment of the risk of rockburst. However, such methods cannot simulate and predict the rockburst process adequately. This research offered a novel numerical simulation method for the rockburst process. The method considered the main factors that affect the occurrence of rock burst, including the high geostress hard rock mechanics model, the rockburst discrimination index, underground excavation methods, and new boundary conditions during rockburst. The rationality of this method is verified by the calculation and analysis of different types of rockburst engineering cases. Compared to traditional rockburst prediction approaches, this method can quantitatively predict the time, location, and degree of damage caused by the rockburst, allowing for the rational selection of support parameters and timing in rockburst prevention. |
