Retest and Results of Control Network of Wujiagang Yangtze River Bridge in Yichang City
Taking Wujiagang Yangtze River Bridge in Yichang City as an example,the implementation and achievements of the retest con-trol network of the bridge are comprehensively combed,this paper analyzed the stability of control points and the reasons for some control point deformations. At the same time,this paper puts forward a targeted solution to the situation of the key control point in this case The project practice shows that the scheme can ensure the continuity of the coordinate datum of the retest control network and the accuracy of the control network and the reliability of the results,which provides an effective control datum for the monitoring work in the subsequent operation stage of the bridge. The research results have good reference significance for other similar projects.
