摘　　要：钢桥面板在车辆荷载作用下,容易产生较大的局部变形。国内对于桥面铺装应力应变分析多采用有限元,实桥长期监测仍然处于空白阶段。该文依托桃浦路蕴藻浜大桥项目,对实桥监测过程中的传感器布设进行了研究。从不同结构、不同用途传感器选取方面入手,对传感器的埋设方案,安装方法进行详细介绍,为以后工程中传感器使用提供了借鉴。The steel bridge deck is easy to have a larger local deformation under the load of vehicles.Stress and strain of the steel bridge deck are analyzed by the finite element in China,but the long-term monitoring of real bridge is still in the blank stage.This paper studies the layout of sensors in the monitoring of real bridge based on the Taopu Road Yunzaobang Bridge Project.The paper introduces in detail the burying scheme and installation method of sensor from the different structures and the different uses of sensors,which can be referred for the use of sensor in the future projects.
