摘　　要：地铁浅埋暗挖法是一项超近距穿越邻近建筑物的施工技术,应用该项技术能实现地铁线路的顺利延伸,不会影响周边建筑物的安全。文中对地铁浅埋暗挖法超近距穿越邻近建筑物施工技术进行研究,在深入分析技术原理、工艺流程和施工实践基础上,给城市地铁建设提供更加科学的施工方案。The shallow buried and concealed excavation method of subway is a construction technology that crosses adjacent buildings at a super close distance.The use of this technology can achieve the smooth extension of subway lines,and its extension will not affect the safety of sur-rounding buildings.The principle of this method lies in a reasonable process flow,combined with key technologies such as soil grouting rein-forcement,temporary inverted arch installation,grid arch foot treatment,backfill grouting operation,and deformation monitoring.Therefore,the article conducts research on the construction technology of the shallow buried and concealed excavation method for subway passing through adjacent buildings at a close distance.Based on in-depth analysis of the technical principles,process flow,and construction practice,it pro-vides a more scientific construction plan for urban subway construction.
