为克服引汉济渭工程秦岭输水隧洞施工过程中的高频高强岩爆问题，通过分析秦岭输水隧洞的地质特征、岩石力学特性及岩爆实际发生情况，开展单洞长度超过13 km连续洞段的以微震监测技术为主的岩爆监测与预警工作，构建移动式24 h连续微震监测系统，建立基于微震能量的岩爆等级评价体系，并提出“以微震能量为主、以微震频次和集中度为辅”的简易定量化判别方法，大大提高了数据的易读性和监测结果的利用效率。应用结果表明： 采用提出的方法后岩爆综合预警准确率达90%，施工过程中未发生因岩爆致人伤亡的事故，保障了工程进度和安全。

Rockburst is one of the primary geological disasters faced by deepburied hardrock tunnels, which severely threatens the life of siteconstruction personnel, affects the construction schedule, and increases the protection cost. To deal with the highfrequency and highstrength rockburst occurring in the Qinling water diversion tunnel of the Hanjiang rivertoWeihe river water diversion project in Shaanxi, China, the geological characteristics, rock mechanical characteristics, and actual occurrence of rockburst in the Qinling tunnel are investigated. Rockburst monitoring and earlywarning works, focusing on microseismic monitoring for more than 13 km of continuous tunnel sections, are conducted. Furthermore, a mobile 24h continuous microseismic monitoring system is constructed, and a rockburst rating evaluation system based on microseismic energy is established. After continuous exploration and comparison, a simple quantitative discrimination method of "microseismic energy as the main, frequency and concentration as the auxiliary" is developed, which remarkably improves the legibility of data and the utilization efficiency of monitoring results. The results show that the comprehensive warning accuracy of rockburst reaches 90%. Moreover, no major accidents caused by rockburst casualties occurred until smooth penetration, effectively guaranteeing the progress and safety of the project.
