允河特大桥高墩测量联合控制

Joint control measure of Yunhe Bridge pier

以允河特大桥高墩测量为例,采用了快速激光垂准仪和全站仪配小棱镜相配合的测量方法,结果在对已完工的高墩实体检查后发现墩台的平面位置都在10 mm以内,垂直度都在0.3%以内,满足了设计和规范要求,并得到了上级单位的认可。

Taking Yunhe Bridge pier measurement as an example, using a measurement method of rapid laser vertical quasi-instrument match- ing total station with a small prism, this paper examines a completed high-per entity and finds that planar location of bridge pier is in 10 mm and vertical degrees are lass than 0.3 %. It meets the design and specification requirement and has been recognized by the higher-level units.
