水电站平面控制网网点稳定性分析及位移修正

Analysis on stability of dots in plane control network and displacement correction

通过对某水电站监测平面控制网复测成果中边长的对比分析、网点稳定性的分析,得出平面控制网网形放大的结论,并估算放大比例,以此对以前的大坝水平位移监测成果进行修正。

By analysis on the side length in remeasurement result and the stability of dots in plane control network, conclusion was gotten that the plane network was amplified. Further, the amplification ratio was calculated and used in correction of monitored horizontal dam displacement.
