| Abstract: | 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 distancemeasuring network and trigonometric leveling is the effective m ethod with the improving accuracy of electronic distance-measuring and the impa ct of water and electric construction conditions.And GPS positioning is becomin g the new method of control survey on construction because of its few limitation,simple operation and high automatic office process. |
