无风撑系杆拱桥健康监测系统设计

Design of Health Monitoring System for Wind-free Braced Bowstring Arch Bridge

随着我国桥梁技术的不断发展以及人们对美观要求的不断提升,各种新颖桥梁被设计建造出来,针对大跨径桥梁有必要建立与其配套的健康监测系统。结合中承式无风撑系杆拱桥受力特点、振动特性、易损部位,设计监测系统硬件布设方案;该监测系统包括硬件布置、数据采集、数据传输、数据存储、状态评估以及预警信息发布。基于监测系的采集数据,可对桥梁技术状况作出分析,为后续同类桥梁设计及监测提供参考依据。

With the continuous development of bridge technology and the continuous improvement of people's aesthetic requirements in China,various novel bridges have been designed and constructed.It is necessary to establish a health monitoring system for long-span bridges.In this paper,combined with the mechanical characteristics,vibration characteristics and vulnerable parts of the half through wind-free braced bowstring arch bridge,the hardware layout scheme of the monitoring system is designed.This monitoring system includes the hardware layout,data acquisition,data transmission,data storage,state evaluation and early warning information release.Based on the data collected by the monitoring system,the technical status of the bridge can be analyzed,which can provide reference for the design and monitoring of similar bridges.
