摘　　要：拱桥是常见的桥型之一,健康监测是了解和掌握桥梁运营期状态的重要手段。文章首先调研分析了影响拱桥运营期安全的风险源;接着介绍了健康监测系统的各组成部分、监测布点确定的原则和方法;最后根据万福快速路京杭大运河大桥结构特点和相关规范要求,确定了健康监测系统的布点位置与数量,为后续同类桥梁健康监测方案的设计提供参考。Arch bridges are one of the common bridge types.Health monitoring is an important means to understand and master the status of the bridge during operation. Firstly, this paper investigates and analyzes the risk sources that affect the safety of arch bridges during operation. Then, the components of the health monitoring system and the principles and methods for determining the monitoring locations are introduced. Finally, according to the structural characteristics of Beijing-Hangzhou Grand Canal Bridge on Wanfu Expressway and relevant specification requirements, the location and quantity of health monitoring system are determined, which provides references for the design of similar bridge health monitoring schemes in the future.
