高海拔区域工程控制网的建立与分析——以青海某选煤厂工程为例

Establishment and Analysis of Engineering Control Network in High Altitude Area——Take a Coal Separating Plant Project in Qinghai as an Example

通过青藏高原某工程项目实例,分析了坐标系的选择及控制测量的成果精度,通过控制点检核,选择可靠的控制点参与平差才能保证成果精度,介绍了在高原地区使用全站仪的注意要点,总结了高原地区应予关注的问题。

Through a project of the Tibetan plateau , this artical analysed the choice of coordinate system and the accuracy of eontral surveying results. Through the inspection of the control points, choose reliable control points in the adjustment in order to ensure the precision of the achievements, introduced the points for attention in the use of total station and summarized problems should be concern in plateau area.
