摘要: 为消除隧道穿越含浅层天然气地层瓦斯给施工带来的安全隐患,对新建兰渝铁路梅岭关隧道所处区域构造位置、地层岩性与浅层天然气构造和储层关系以及天然气储集层的类型、发育特征对隧道的影响等方面进行系统详尽的研究,并通过施工揭示天然气涌出情况和监测分析其涌出规律等提出针对性预防措施,指出浅层气对梅岭关隧道的危害程度。

Abstract: Superficial natural gas contained in strata would bring safety risks to tunneling. The position of the regional structures, the lithology, the relationship between the superficial gas formation and the gas storing layers, the influence of the types and development features of the natural gas storing layers on tunneling are studied in detail, with Meilingguan tunnel on LanzhouChongqing railway as an example. Gas prevention and control measures are proposed on basis of the actual situation of the gas emission after excavation and analysis on the gas emission rules. The degree of the influence of the superficial gas on the construction of Meilingguan tunnel is provided.

Key words: LanzhouChongqing railway, Meilingguan tunnel, superficial natural gas, stratum lithology, gas formation and gas storing layer, gas emission 
