摘　　要：桥梁伸缩装置是公路桥梁中十分重要的功能构件,其服役安全性直接影响桥梁运营的安全性;桥梁伸缩装置需要适应桥梁因温差变化等引起的桥梁伸缩变形,同时又要保障桥面车辆安全平稳地运行通过。由于桥梁大位移伸缩装置结构复杂、安全重要性高等特点,为解决传统接触式引线检测方式在桥梁大位移伸缩装置中不易实现的问题,提出一种适用于桥梁大位移模数式伸缩装置的智能监测系统,包含视觉监测、图像识别和故障分析、判定算法等。采集车辆通过伸缩装置的载荷激励下桥梁伸缩装置的位移及振动响应数据,通过故障分析、判定算法准确识别并分类判定桥梁伸缩装置的故障状态,为桥梁伸缩装置的服役安全性提供可靠监测。The bridge expansion device is a very important functional component in highway bridges,and its service safety directly affects the safety of the bridge operation.The bridge expansion device should adapt to the bridge deformation caused by temperature difference changes,and at the same time to ensure the safe and stable operation of vehicles on the bridge deck.In response to the complex structure and safety importance of bridge large displacement expansion and contraction devices,and to solve the problem of difficult implementation of traditional contact wire detection methods in bridge large displacement expansion and contraction devices,an intelligent monitoring system for large displacement modular expansion device of bridge is proposed,which includes visual monitoring,image recognition,fault analysis and decision algorithm.The displacement and vibration response data of bridge expansion device under the load of vehicle are collected,and through fault analysis and judgment algorithms to accurately identify and classify the fault status of large displacement expansion devices,providing reliable monitoring for the service safety of bridge expansion devices.
