上海城市快速高架道路健康监测系统的设计与应用——以内环高架(四平路—政本路)“年轻化”工程为例

Design and Application of Shanghai Urban Rapid Elevated Road Health Monitoring System:Taking the"Youthfulness"Project of the Inner Ring Elevated Road(Siping Road to Zhengben Road)as an Example

上海市内环高架,是上海最早建设的城市快速高架道路,建造年代较久,内环高架路浦西段服役年限已达29年,结构存在不同程度病害。针对内环高架“年轻化”改造及后期运营,设计并应用了适配的结构健康监测系统,全时监测车辆动态信息和主梁工作性能等方面,为加强城市快速高架道路桥梁安全运营管理发挥了积极作用,也为同类项目的实施提供了借鉴参考。

The Inner Ring Elevated Road in Shanghai is the earliest urban expressway constructed in Shanghai.It has been built for a long time,and the Puxi section of the Inner Ring Elevated Road has been in service for 29 years,with varying degrees of structural damage.This article focuses on the"rejuvenation"transformation and later operation of the inner ring elevated road,and designs and applies an adaptive structural health monitoring system to monitor vehicle dynamic information and main beam performance at all times.It plays a positive role in strengthening the safety operation management of urban rapid elevated road bridges and provides reference for the implementation of similar projects.
