水布垭水利枢纽大坝及放空洞工程加密控制测量

Refined Control Measurement of Shuibuya Hydro-junction's Dam and Sump Tunnel

水布垭水利枢纽施工加密控制测量是施工测量中的关键环节,只有选定适宜的布网形式,合理地控制点位,使控制点坐标达到相应的精度,才能满足工程施工的各项要求。系统地介绍了水布垭水利枢纽加密控制外业测量及导线测量内业计算的方法和步骤。

The refined control measurement of Shuibuya hydro-junction is the key link of the construction measurement, only selecting the proper net-arranging form, making rational control of the points, and making the control points' coordinates to reach the corresponding precision, can satisfy the all requirements of the engineering construction. This paper systematically introduces the methods and procedures for the internal work's calculation for the refined control external work measurement and traverse measurement of Shuibuya Hydro-junction.
