铁路瓦斯隧道施工中若干问题的对比研究——天坪隧道瓦斯突出工区施工案例分析

摘要

In order to solve some key challenges in the construction of railway gas tunnels, especially tunnels with gas bursts, a comparative study on the problems related to the existing specification, design, construction and man-agement is conducted based on the construction practice of a gas burst section of the Tianping tunnel on the Chongq-ing-Guizhou railway and experience with similar coal mining projects. Suggestions such as optimization of grading for gas tunnels, establishing observational evaluation systems and organization and management modes are proposed.%为了解决铁路瓦斯隧道,尤其是瓦斯突出隧道施工中的重、难点问题,文章通过渝黔铁路天坪隧道瓦斯突出工区的施工实践,结合煤矿类似工程,对现行规范以及设计、施工、管理中存在的诸多问题进行了对比分析研究,提出了进一步优化瓦斯隧道等级划分、建立合理的动态评价体系和组织管理模式等建议.
