摘　　要：城市轨道交通工程主要位于城区繁华地段,周边环境复杂,地下管线众多,施工难度较大。明挖法作为地铁出入口常用的施工方法,具备诸多优点,但对道路通行及现状设施的运行都会产生较大影响。浅埋暗挖法在道路通行要求严格、地下管线复杂地段就体现出其优越性。本文结合长沙市地铁6号线农科院农大站4号出入口浅埋暗挖通道穿越高富水砂卵石地层的成功实例,对浅埋暗挖法通道在复杂环境下的施工技术进行研究,为后续浅埋暗挖施工提供可参考的施工经验。Urban rail transit engineering is mainly located in the downtown area,the surrounding environment is complicated,there are many underground pipelines,and the construction is difficult.As a common construction method of subway entrance and exit,open-cut method has many advantages,but it will have a great impact on the road passage and the operation of current facilities.The shallow excavation method shows its superiority in the area with strict road passing requirement and complex underground pipeline.Based on the successful example of a subway entrance in Changsha City,the paper studies the construction technology of shallow buried tunnel under complex environment,and provides reference construction experience for subsequent shallow buried tunnel construction.
