Double Arch Bridge demolition is a kind of work with high technique. On-site security monitoring is important in bridge construction monitoring. With engineering examples, this paper studied security control indicators, and gave specific indicators for control. Only to ensure the safety of the removal process, can we talk about on the completion of the bridge and other control, to guide the similar construction.%双曲拱桥拆除是一项技术性很强的工作,现场安全监控是桥梁施工监控中的重要内容,本文结合工程实例,研究安全控制指标,给出依托工程控制具体指标,只有保证拆除过程安全性,才谈得上其他控制与桥梁的完成,可指导今后类似的施工.
