摘　　要：使用Topcon Hiper双频GPS接收机,对谭庄水库大坝各监测点进行多年观测,通过精密解算获得的水平位移和垂直位移量可达到毫米级乃至亚毫米级的精度,可对水库大坝较大变形进行预警,为大坝的稳定性、安全性和防洪决策提供了科学依据。The GPS satellites signal for several years is obtained at various detecting points of Tanzhuang reservoir dam with high-precision Topcon Hiper double frequency GPS receivers. The computing precision can be up to mm level even to sub-ram for horizontal and vertical displacement. So, the GPS static positioning can be used in the presentiment of larger dam deforming and provides the scientific gist of the dam＇s stability, security and flood-prevention via improving the surveying precision and optimizing the data computing method.
