摘　　要：作为2022年中国冬奥会重大交通保障项目,延庆至崇礼高速公路的松山隧道和翠云山隧道工期紧迫,为了加快施工进度,松山隧道采用迂回导洞方案,翠云山隧道采用施工斜井分岔方案,论文分别分析了这两种方案提出的原因、具体内容以及实施效果。实践结果证明,两种方案极大地加快了施工进度,为工程按期完工奠定了基础。As a major transportation support project for the 2022 Winter Olympics in China,Songshan Tunnel and Cuiyunshan Tunnel from Yanqing to Chongli Expressway are in a tight schedule.In order to speed up the construction progress,Songshan Tunnel adopts the detour guide tunnel scheme and Cuiyunshan tunnel adopts the construction inclined shaft branching scheme.This paper analyzes the reasons,specific contents and implementation effects of these two schemes respectively.The practical results show that the two schemes greatly accelerate the construction progress and lay the foundation for the completion of the project on schedule.The practical results show that the two schemes greatly accelerate the construction progress and lay the foundation for the completion of the project on schedule.
