摘　　要：城市轨道交通发展迅速,但挤占的地下空间导致后续市政、公路的桥梁桩基施工与之发生日益加重的空间冲突。全回转套管钻机因其自身微扰动、质量高、风险小的特点得到了越来越广泛的应用。以北京通州文化旅游区东六环西侧路(施园街–张采路)5号桥桩基临近八通线地铁施工为例,进行全回转套管钻机在邻近地铁的富水砂层中的应用研究,以期为今后类似工程提供参考。Urban rail transit develops rapidly but the underground space occupied by it will lead to increasingly serious space conflict between urban rail transit and subsequent bridge&pile foundation construction for municipal and highway works.Full-rotary casing drill has been more widely used by virtue of its tight disturbance,high quality and low risk etc.Taking the construction of pile foundation for 5#bridge of East 6th Ring West Road(Shiyuan Street~Zhangcai Road)in Tongzhou Cultural Tourism Zone Beijing adjacent to Batong Line for example,research on application of fully-rotary casing drill in water-rich sand stratum nearby subway is done,to provide reference to similar projects in future.
