| 摘 要： | 天然气高瓦斯隧道中的瓦斯不可预见性很大。施工过程中，在遇到隧道洞身段局部岩体节理裂隙发育、围岩破损带、断层处，均可能发生瓦斯逸出甚至瓦斯突涌现象，现场存在很大的瓦斯安全隐患。主要研究了TSP探测、地质雷达、超前钻探等方法在瓦斯隧道施工中的应用情况，多种物探手段与钻探相结合对不良地质体进行综合预测，取得了较好的预报效果，有力保障了现场施工安全。

| Abstract: | The gas in the high-gas natural gas tunnel is unpredictable.During the construction process，gas leakage and even gas surge may occur at the local rock mass joint cracks，surrounding rock damage zones，and faults in the tunnel body，resulting in great gas safety risks on site.Mainly studied the application of TSP detection，geological radar，advanced drilling and other methods in the construction of gas tunnels.A variety of geophysical methods combined with drilling were used to comprehensively predict bad geological bodies and achieved good prediction results，which effectively guaranteed the site construction safety. |
