系杆拱桥健康监测系统研究——以青山河特大桥为例

Research on Health Monitoring System of Tied Arch Bridge--Taking Qingshanhe Grand Bridge as an example

桥梁健康监测系统是智慧高速建设的重要组成部分,是桥梁安全运营的重要保障。结合宁芜高速改建智慧高速试点工程,本文通过调研国内已实施的系杆拱桥健康监测系统项目,利用有限元软件分析了系杆拱桥结构受力特征,在此基础上重点探讨了系杆拱桥健康监测系统设计需注意的关键问题,为类似工程提供参考。

Bridge health monitoring system is an important part of Smart highway construction and an important guarantee for bridge safe operation.Combined with the Ningwu high-speed reconstruction intelligent high-speed pilot project,this paper investigates the health monitoring system project of tied arch bridge implemented in China,analyzes the structural stress characteristics of tied arch bridge by using finite element software,and on this basis focuses on the key issues that should be paid attention to in the design of health monitoring system of tied arch bridge,so as to provide reference for similar projects.
