摘　　要：近年来,临近地铁车站或区间隧道进行地块大面积开挖的项目越来越多,为严格控制地铁车站和隧道的变形,论文提出了大型基坑分块开挖、采用型钢组合支撑轴力伺服系统、优化桩基施工工艺、控制降水等众多变形控制措施,以减小对临近既有设施的影响。In recent years,there are more and more large-area excavation projects have been carried out near subway stations or interstation tunnels.In order to strictly control the deformation of subway stations and tunnels,this paper proposes many deformation control measures,such as large foundation pit excavation in blocks,the use of section steel combined support with axial force servo system,optimization of pile foundation construction technology,and control of precipitation,in order to reduce the impact on adjacent existing facilities.
