Abstract: In recent years，urban rail transit construction started in many cities，which has led to the emergence of super deep foundation pit and super large foundation pit.In Shijiazhuang area，the depth of subway foundation pits is generally between 15mand 25m，which are dangerous projects.In this paper，combined with the design of the supporting scheme of the deep foundation pit of Nanwei station of Shijiazhuang Metro Line 2，the design process is systematically introduced，and a reasonable construction scheme is put forward.The field monitoring data show that the design scheme is reasonable.

Key words: subway station, deep foundation pit, inner bracing system, deformation monitoring

摘要： 近年来,各地开始城市轨道交通建设,超深基坑、超大基坑层出不穷。在石家庄地区,地铁基坑的深度一般在15～25m之间,基坑深度较大,属于危险性较大工程。文中结合石家庄地铁2号线南位站深基坑工程支护方案设计,系统介绍设计过程,并提出合理的施工方案,通过现场监测数据表明设计方案合理。
