摘要:随着城市基础设施的持续建设，城市轨道交通建设得到快速发展。但受旧有城市规划的制约，新的地铁在施工中将不可避免地会部分穿越既有建(构)筑物的基础。如何进行既有建筑物桩基的托换施工及风险控制成为地铁施工中不可避免的技术、管理问题。本文以某城市地铁车站高架桥墩桩基托换为例，对桩基托换方案设计、施工工艺及安全监测工作等做了详细论述，为在复杂施工环境和地质条件下进行既有桥梁桩基托换的施工技术及安全风险管理工作积累了宝贵的经验。
Abstract: Railway construction has been developed rapidly. But during the construction of a new subway, the tunnel will inevitably pass through the foundation of buildings. How to control the risk of underpinning construction and protect existing buildings becomes an inevitable challenge. The paper focuses on the management and technology used in Viaduct Pile foundation underpinning, elaborates the design, construction technology and safety monitoring work. The provided valuable experience of bridge pile foundation underpinning construction in complex environments and geological conditions is helpful to security risk management.
