全Ⅴ级围岩下小净距隧道施工技术研究

RESEARCH ON THE CONSTRUCTION TECHNOLOGY OF THE SMALL CLEAR DISTANCE TUNNEL UNDER THE FULL V CLASS SURROUNDING ROCK

小净距隧道施工具有造价低廉、工艺简单、工期较短等优点。以宿松县S249项目为例,介绍全Ⅴ级围岩下小净距隧道施工技术,旨在为类似隧道工程施工提供参考,以进一步提高项目建设的质量安全。

Small net distance tunnel construction has the advantages of low cost,simple process and short construction period.Taking S249 project in Susong county as an example,this study introduces the construction technology of small clear distance tunnel under the full V class surrounding rock,aiming to provide reference for similar tunnel engineering construction to further improve the quality and safety of the project construction.
