GPS在石门子水库副坝变形监测中的应用

Application of GPS in Deformation Monitoring of Dam Shimenzi Reservoir

以石门子水库副坝(土石坝)变形监测为例,介绍了其监测方法及对观测数据的处理和分析,采用GPS平面拟合高程进行水库竖向位移监测,其精度与三等水准精度相当,而且可以将平面与竖向位移同时观测,大大提高了测量效率,节省了人力和物力。

Taking Shimenzi reservoir auxiliary dam deformation monitoring as an example,the monitoring method,the observation data processing,and analysis is introduced,The vertical displacement of reservoir is monitored by GPS plane fitting,and the precision is equivalent to the level of three.The measuring efficiency is greatly improved,and it saves manpower and material resources.
