摘要
隧洞施工,需要建设各方密切配合,根据围岩变化及时确定安全可靠、经济合理的支护措施和施工方案。就隧洞施工中的动态设计、超前预报、开挖方式、初期支护、二次衬砌与掌子面的距离等常常遇到的若干技术问题结合有关技术文件和规范进行了探讨,希望能引起引汉济渭工程建设者的关注。
The tunnel construction takes very close and active cooperation from all the parcipants involved in the construction, and particularly the timely determination of the safe, relialbe, economical and reasonable supporting measures and constrcution method according to changes of the surrounding rock. This paper explores several technical questions such as the dynamic tunnel construction design, advanced prediction, excavation method, initial support and secondary lining and working face distance, and discusses the related technical sepcifications, standards and norms in the hope to attract due attention from the participants of the project construction.
