上海长江大桥竣工荷载试验变形监测方法技术

上海长江大桥通车前夕,主桥斜拉桥进行了荷载试验,共用总重30吨加载车辆60辆,分不同工况对主桥各个控制断面挠度、塔顶位移、伸缩缝位移等参数进行测量。监测中采用全站仪自动化监测技术对主桥的各种形变参数进行了准确有效的测量,保证了竣工荷载试验顺利完成。自动化全站仪系统由自动照准测量全站仪以及定制机载软件和数据分析系统组成。

Distortion Monitoring in Completion Load Test of Shanghai Yangtze River Bridge

Before the opening of ShanghaiYangtze River Bridge,a completion load test was taken on the mainbridge.During the load test,the distortion monitoring was taken for various deformation parameters.Automatic total station measurement system,consisted of the data analysis software and onboard software,was adopted to ensure the accurate of various deformation parameters of main bridge and effectively ensure completion of load test successfully.
