下沉式地道下穿高铁施工技术研究

国内城际高铁已在多个城市间开通,运行速度高达300 km/h,然而城市建设规划中不可避免地会遇到市政道路横穿高铁线路的情况。目前国内高铁线路的下穿工程实例较少,本文主要介绍了天津市航新路下穿津秦客专、京津城际延伸线工程的设计、施工技术,为此类工程提供可供借鉴的工程经验。

Study on Construction Technology of Submerged Tunnels Under High-speed Railway

Domestic high-speed intercity railway has been opened between a number of cities with a running speeds of up to 300 km/h. However, in city planning it will be inevitable for meet municipal roads to across the high-speed railway line. At present, there are only a few engineering practices of construction underpass high-speed railway line, the paper mainly introduces underpass Jinqin passenger dedicated line of the Hangxin Road in Tianjin, and the design and construction technology of Beijing-Tianjin intercity extension, which can be taken for references for similar engineering project.
