隧道工区瓦斯等级可拓评价体系研究

Studies on Extension Evaluation System of Gas Level in Tunnel Work Areas

文章介绍了隧道瓦斯工区等级可拓法评价流程,并将瓦斯地质学的理论知识应用于隧道工程领域,对影响隧道工区瓦斯赋存的因素进行了深入分析,同时采用国际上广泛使用的SMART指标体系设计准则,建立了隧道工区瓦斯等级评价指标体系及瓦斯工区等级评价物元模型。通过实例研究表明,该模型得到的结果与实际情况基本吻合,具有一定的现实参考价值。

This article introduced the evaluation process of tunnel gas work-area level exten- sion method,applied the theory knowledge of gas geology in the field of tunnel engineering, and conducted the in-depth analysis on the factors affecting the gas occurrence in tunnel work areas,while using the SMART indicator system design criteria widely used internation- ally, it established the gas level evaluation indicator system of tunnel work areas as well as the matter element model of gas work-area level evaluation.The practical case studies showed that the results obtained from this model are basically consistent with the actual situ- ation,thus it has some practical reference value.
