摘要为了提高施工效率，降低现场施工人员和设备的风险，锦屏二级水电站1#、3#引水隧洞采用大断面TBM进行施工。超大埋深TBM全断面施工，对于等级较强的岩爆，仍然可能会给TBM设备带来一定伤害。为此，通过微震实时监测和数值分析等手段，开展了TBM施工速度、导洞施工等TBM开挖方案对岩爆风险的影响研究。结果表明，降低TBM施工速率，有利于降低岩爆发生的风险；导洞施工+TBM联合施工对于极强岩爆风险的防范是十分有利的。研究成果可为TBM安全快速掘进提供重要的参考价值，也将为其他工程提供借鉴，具有重要的工程价值。

Abstract：To improve efficiency of construction and reduce the risk of site construction personnel and equipment，the 1#，3# diversion tunnel of Jinping II hydropower station adopt large-section TBM for construction. The full-section TBM construction under large buried depth，when encounter strong grade rock burst，it still may bring some damage to TBM equipment. Therefore，through the real time microseismic monitoring and numerical analysis，study the influence of TBM excavation scheme、heading construction on the risk of rock burst. The results show that，lowering the rate of construction，can reduce the risk of rock burst；pilot excavation and TBM joint construction is advantageous to prevent strong grade rock burst. The research results can provide important reference value for the safe and rapid excavation of TBM，will also provide reference for other similar project，it has an important engineering value.

Key words： deep buried long tunnel TBM excavation scheme rock burst evolution
