摘要
结合嘉陵江大桥加固工程的建设实际,在旧桥不减载的情况下,采用全站仪对大桥拱轴线进行监测。采用三角高程测量法计算观测点的高程坐标;再根据各观测点的高程值计算各点的挠度,比较挠度的实际迭加值和设计的理论迭加值,二者的差异在许可范围内,从而确认该方法切实可行。该监测分析方法可为同类工程提供参考。
Combined with the actual works of reinforcement for Jialing River Bridge with full cargo for old bridge,total station monitoring was conducted for the arch axis of this large bridge.Trigonometric Leveling Method was used to calculate the coordinates of the observation point elevation;according to the observation point elevation values calculated for each point of deflection was calculated,the actual Diego bonus and the design theory Diego added value were compared.The difference was in permission range,which confirmed that the method was feasible.The monitoring and analysis methods can provide reference for similar projects.
