摘　　要：文中以某基坑工程为例,分析了邻近既有地铁车站的结构形式和工程所在地的岩土水文地质情况,研究了邻近既有地铁的基坑工程静压PHC管桩、SMW工法桩施工技术,提出了基坑土方开挖、地铁出入口、景观回填、地铁保护监测等施工措施,确保施工期间既有地铁的结构安全与运营稳定,可为类似工程提供参考。this paper analyzes the structural form of the adjacent existing subway station and the geotechnical and hydrogeological conditions at the project site.It studies the construction techniques for static pressure PHC pile and SMW method pile used in foundation pit engineering adjacent to existing subways.The paper also proposes construction measures for earthwork excavation of foundation pits,subway entrances and exits,landscape backfilling,and subway protection monitoring,to ensure the structural safety and operational stability of the existing subway during construction.This paper provides a reference for similar projects.
