安康水电站坝址区变形观测系统

Deformation Obervation Network At the Dam Site Area of Ankang Hydropower station

本文简单介绍了安康水电站拦河坝外部观测系统，并论述了坝址区水平位移观测网的布设和观测方法及精度估算。另外，还根据近几年来观测技术的发展和高精度观测仪器的产生及引进使用情况，对安康水电站拦河坝下游观测网提出了改进性建议。

The external observation system at the dam site area of Askang hydropower station wasdescribed,then the layout of horizontal displacement observation network, the observation method andaccuracy were also disccused in this paper.According to the development of observation technologyand high accuracy instrument,the improvement of observation network was suggested.
