摘　　要：岩爆是深埋长大隧道主要的工程地质问题之一,对隧道工程的危害很大,岩爆的预测研究对于隧道的设计和施工有着重要的意义。通过对九岭山隧道初步设计及施工图设计两阶段工程地质勘察成果的研究,分析该隧道的工程地质条件、岩石力学性质及地应力测试结果,并运用现有国内外多种岩爆判别准则对其在施工期间可能发生的岩爆问题进行了预测研究。结果表明,九岭山隧道在施工期间不会出现严重的岩爆,但在埋深大于450m的洞段可能会产生低岩爆活动。Forecasting the rock-burst of the deep and long highway tunnel is helpful for tunnel design and construction,because rock-burst is harmful to tunneling engineerings and it is the one of main engineering geological problems in the deep and long highway tunnel. Two-phase engineering geological survey results of the Jiuling shan tunnel preliminary design and construction drawing design were studied. Engineering geological condition,rock mechanical properties and stress test results had been analyzed. It forecasted the rock-burst questions which may occur during the construction by using domestic and overseas varieties of rock burst criterions. The study results show that there is not serious rock-burst,but threr will be have a low rock burst activity in the depth of greater than 450m.
