铜陵长江大桥线形测量与分析

Linear Measurement and Analysis of Tongling Yangtze River Bridge

为研究铜陵长江大桥的运营情况,文章确定测量基准点和监测点,分别对主引桥的空间挠度、索塔位置、江北桥墩的间距和梁长进行了线形测量和分析。结果表明:铜陵长江大桥四年来的空间线形基本一致,反映出桥梁的运营状况良好。

In order to study the operation situation of Tongling Yangtze River Bridge,this article determines the measurement reference point and monitoring point,and performs the linear measurement and analysis on the spatial deflection of main bridge and approach bridge,the cable tower position,as well as the spacing and the beam length of Jiangbei pier.The results show that the spatial line shape of Tongling Yangtze River Bridge is basically the same in the past four years,reflecting the good operation status of the bridge.
