Based on the open-cut construction of Shensuxilu station in Shenyang Subway Line 9 this paper analyzes various factors of the station and puts forward bilateral step method.The method can speed up the rate of soil excavation and construction which is beneficial to support of the foundation excavation sidewalls reduce the deformation and ereep on foundation excavation on both sides. Key words:subways;open-cut stations influencing factors;construction 0引言 沈苏西路车站位于浑河站街与浑南西路交叉 随着沈阳城市的扩建、经济的发展和人口数量的路口西侧.该车站的东北角是1栋7层住宅，车 的提升，沈阳地铁的建设工程项目也逐渐增多，地 站的西北角是1个220kV高压铁塔，车站上方横跨 铁车站是地铁建设的...
