摘　　要：对香丽高速公路某隧道地应力测试成果进行了综合分析,并对该隧道的初始应力场进行了拟合。采用应力条件预测法及岩爆倾向性预测法对该隧道岩爆的可能性进行了预测分析,并通过参数反演对比经验公式,提出了该隧道各等级岩爆发生的临界深度,以期为隧道设计施工提供参考。A comprehensive analysis was conducted on the results of in-situ stress testing in a tunnel on the Xiangli Expressway,and the initial stress field of the tunnel was fitted.The study used stress condition prediction method and rockburst tendency prediction method to predict and analyze the possibility of rockburst in the tunnel.By comparing empirical formulas through parameter inversion,the critical depth of rockburst occurrence for each level of the tunnel was proposed,in order to provide reference for tunnel design and construction.

关 键 词：隧道 岩爆 临界深度
