摘要
介绍了在沉管隧道施工中 ,实时监测沉管沉放的一种测量方法。它利用全站仪观测数据 ,通过坐标系之间的坐标转换 ,实时计算沉管管体特征点的坐标 ,从而对沉管的沉放过程进行实时监测。
A surveying method of real time monitoring for immersed tube was introduced. Total station theodolites were used to observe reflectors. Coordinate transformation between different reference frames was used to calculate the coordinates of characteristic points on tube. This method can monitor tube real time.
