摘　　要：深埋隧洞工程的岩爆孕育机理决定了岩爆支护系统和防控策略的制定,对工程施工安全具有重要意义。结合锦屏二级水电站深埋水工隧洞岩爆案例所揭示的规律,包括岩爆类型、发育特征,开展了岩爆案例反演和孕育机理解译研究,揭示了深埋隧洞施工期各类岩爆的发生机制,制定了不同类型岩爆的防控原则,提出了钻爆法和TBM掘进条件下岩爆的防控措施。The formulation of rock burst prevention and control strategies for deep buried tunnel engineering depends on the mechanism of rock burst, which is of great significance for construction safety. The objective law of rock burst is revealed based on the deep buried tunnel engineering cases of Jinping I1 Hydropower Station, including the type of rock burst and the development characteristics. The rock burst case inversion and interpretation are also studied, and the mechanisms of various types of rock burst in the construction of deep buried tunnel engineering are revealed. The prevention principles of different types of rock burst are formulated based on these results, and the rock burst prevention and control measures under the condition of D＆B and TBM construction methods are also presented.
