新建地下室临近既有地铁车站设计及影响分析

Design and Impact Analysis of the Newly-built Basement Adjacent to the Existing Metro Station

临近沈阳市地铁长青南街站主体及B出入口新建两层明挖地下室,存在较大施工风险。文章采用有限元模拟分析,计算了地下室施工对长青南街站主体结构及出入口的影响,并对车站主体及附属结构的安全性进行了评价。研究认为,在城市规划过程中,先施工项目应为后期穿越项目预留条件,降低后期施工风险,节约工程造价。

The newly-built two-storey open-cut basement near the main body and entrance and exit B of Changqing south street station of Shenyang metro has a large construction risk.The influence of basement construction on the main structure and entrance and exit of Changqing south street station is calculated by the finite element simulation analysis,and the safety of the main body and auxiliary structure of the station is evaluated.The research shows that,during the process of urban planning,the first construction project should reserve conditions for the later crossing project,reduce the later construction risk,and save the project cost.
