摘要
介绍了采用测边三角网和GPS静态测量实施三峡工程加密控制网的应用情况,阐述了随着光电测距精度的不断提高及水电施工环境的影响,采用测边网加测距三角高程网实施控制网加密是当前行之有效的一种好方法;此外,GPS测量以其限定条件少、操作简单、高自动化的内业处理等优点为施工控制测量开辟了一条新途径。
This paper introduced the application of distance-measuring triangulation network and GPS static positioning on the construction of control survey of Three Gorges project. It discussed that the control survey using distance-measuring network and trigonometric leveling is the effective method with the improving accuracy of electronic distance-measuring and the impact of water and electric construction conditions. And GPS positioning is becoming the new method of control survey on construction because of its few limitation, simple operation and high automatic office process.
