摘要

研究目的：随着我国基础交通的建设和发展,穿越煤系地层和赋存瓦斯的隧道越来越多,隧道施工瓦斯灾害事故也在不断地增加,因此需研究符合隧道工程特点的瓦斯灾害危险性评价体系。

研究结论：本文在研究我国大量已有瓦斯隧道的基础上,通过对影响隧道瓦斯灾害危险性的地质因素、瓦斯因素和施工时人为因素等研究,初步建立了一套较为完善的隧道工程瓦斯灾害危险性评价技术方法体系。该体系包括瓦斯隧道分级评价、瓦斯隧道施工危险性评价、瓦斯隧道施工掌子面突出危险性评价3个层次,从而保证了在隧道选线、设计、施工阶段均能实现对瓦斯灾害进行快速、准确的评价,进而采取相应的工程防治措施。

Abstract

Research purposes：With construction and development of the transportation infrastructures in China, more and more tunnels pass through coal measure strata and the area with gas to make gas accidents on the rise. Therefore, it is so urgent to study the gas disaster danger assessment system which conforms to the characteristics of tunnel engineering.

Research conclusions：Based on the researching the gas tunnels in China from the areas of the geological sectors, gas sectors and man-made sectors of influencing the danger of gas disaster in tunnel during construction, a relatively perfect gas disaster danger assessment system for tunnel is presented. This system can do the assessments at three levels, namely, gas tunnel classification assessments, danger assessment of gas tunnel construction and danger assessment of tunnel working face, to make a prompt and accurate assessment of gas disaster in the phases of route selection, design and construction, and take appropriate engineering control measures.
