摘　　要：墩台沉降及位移观测是新建特大桥投入运营初期的重点观测项目 ,结合芜湖长江大桥正桥桥跨长、观测条件限制多的特点 ,在测量中采用全站仪测微倾角法 ,使问题得到很好地解决 。Settlement and displacement of piers and abutments are major items of observation for newly built and just opened to traffic super large bridges. Total station micro inclination angle measurement was adopted for Wuhu Yangtze River Bridge, overcoming such difficulties as long span and many limitations on observation, providing full and accurate data for safe operation of the bridge
