摘要:
隧道瓦斯和浅层天然气溢出一直是困扰隧道安全施工的一大难题，也是隧道工程常见病害的主要类型之一。在隧道施工时，若有高浓度瓦斯溢出，可能存在瓦斯爆炸的风险，而部分线路长度较短、隧道埋深较浅，浅层天然气的预测预报容易被忽视。本文以成都-天府国际机场快线为研究对象，针对区域构造条件、现场钻孔天然气测试及室内试验三方面结果进行分析研究，研究表明浅层天然气对隧道能够带来较大安全隐患，隧道勘察设计期间有必要开展关于浅层天然气的专项勘察研究。
Abstract:
Spill of tunnel gas and shallow natural gas is a difficult problem. For tunnel safety construction, and it is also one of the main common diseases in tunnel engineering. There is a risk of gas explosion if there is spillover of gas with high-concentration during tunnel construction. As some railway lines are featured by short length and shallow-depth tunnel, the prediction of shallow natural gas is easy to be ignored. Taken Chengdu-Tianfu airport express as the research object, Analysis and research are taken from the results of 3 aspects, namely, the regional structural conditions, on-site borehole gas testing and laboratory test. Research shows that the shallow natural gas can bring great hazard to tunnel safety. It is necessary to carry out special investigation and research on shallow natural gas during survey and design period of tunnel.
