摘　　要：随着城市地铁线路的不断规划及新建,换乘车站的枢纽作用也日渐凸显。主城区中在既有车站旁新建车站及区间时对周边环境的保护至关重要。文章以杭州地铁4号线二期工程金家渡站为例,对其多种工况进行介绍,并阐述了邻近既有运营车站的端头井结构施工及盾构下穿施工工序,以及既有2号线车站测点布置,最后就施工对毗邻运营地铁车站的变形影响进行了研究,可为后续施工提供参考。With the continuous planning and construction of urban subway lines,the pivotal role of transfer stations has become increasingly prominent.It is very important to build new stations and sections near existing stations in the main urban area for the protection of the surrounding environment.Taking Jinjiadu Station of Hangzhou Metro Line 4 Phase II Project as an example,this paper introduces its various working conditions,and expounds the construction process of the end shaft structure and the shield underpass adjacent to the existing operating stations,as well as the layout of the measuring points of the existing line 2 stations.Finally,the deformation influence of the construction on the adjacent operating subway stations is studied,which can provide references for the subsequent construction.
