Construction Technology of Deep Excavation for Subway Station Adjacent to Railway

摘要:

天津地铁3号线张兴庄站紧邻北环铁路,铁路路基及列车动载产生的偏压荷载对基坑稳定性影响不容忽视。对其基坑加固支护、降水、封堵等施工方案及措施进行详细阐述，对以后类似工程的设计和施工提供参考。

Abstract:

A subway station in Tianjin is adjacent to Beihuan railway, the influence of eccentric loading produced by railway subgrade and dynamic load of driving train is indispensable. The paper described the construction plans and measures of excavation reinforcement, dewatering and sealing, these could be the reference to the design and construction for similar project.
