摘　　要：地铁隧道建设已成为我国当前社会发展的重要组成部分,在很多城市中都扮演着越来越重要的角色。南京地铁7号线马家园车辆出入段区间线路下穿铁路咽喉区,具有超浅埋、大下坡、小净距的工程特点,同时存在施工难度大、安全风险高的问题。文章以该工程项目为背景,提出了矿山法、盾构法与明挖法相结合的多工法组合方案,并着重对盾构法施工技术开展了重难点分析。在此基础上,针对性地提出了相应的解决方案,为今后类似工程提供参考。Subway tunnel construction has become an important part of China's social development and plays an increasingly important role in many cities.The section line of Majiayuan vehicle entrance and exit section of Nanjing Metro Line 7 passes through the throat area of the railway,which has the engineering characteristics of super-shallow buried,large downhill and small clear distance.At the same time,it also has the problems of difficult construction and high safety risk.This study proposed the multi-construction method combination scheme of mining method,shield method and open-cut method,and focuses on the key and difficult points of shield construction technology.On this basis,the corresponding solutions are proposed,which can provide references for similar projects in the future.
