摘　　要：随着大跨、轻、柔等新型桥型的不断建造,桥梁结构的运营安全性及耐久性受到工程界高度重视。桥梁健康监测系统在应急管理和养护管理中发挥决策指引的重要功能,当前已成为大跨度桥梁的关键性配套内容。桥梁监测系统构建的关键性内容之一是桥梁监测内容设计,监测内容、功能目的及位置数量设计的合理性直接决定了运营期监测系统价值的发挥。以六横公路大桥项目二期工程双屿门大桥(主跨1768 m单跨吊钢箱梁悬索桥)健康监测系统的方案设计为背景,介绍了跨海悬索桥主要监测点设计思路,重点论述了桥梁结构特点、运营养护关注点及针对性的监测内容设计,并探讨了数据分析方法思路,为双屿门大桥及同类大跨度缆索体系桥梁结构的健康监测系统设计提供参考。With the continuous construction of new types bridges such as large-span,lightweight,and flexible shaped,the operational safety and durability of bridge structures have been highly valued by the engineering industry.The bridge health monitoring system plays an important role in decision-making guidance in emergency management and maintenance management,and has become a key supporting content for large-span bridges.One of the key components of building a bridge monitoring system is the design of bridge monitoring content.The rationality of the design of monitoring content,functional purposes,and the number of locations directly determine the value of the monitoring system during operation.In the paper,the design of the health monitoring system for the Shuangyumen Bridge(a single span suspended steel box girder bridge with the main span of 1768 m)in the second phase of the Liuheng Highway Bridge project being the background,the design ideas of the main monitoring points of the cross sea suspension bridge is introduced,focusing on the structural characteristics of the bridge,the highlight points of operation and maintenance and the targeted monitoring content design.The data analysis methods and ideas are explored at the same time.The paper may provide reference for the design of the health monitoring system for the Shuangyumen Bridge and similar large-span cable system bridges.
