利用GPS定位技术进行大坝变形观测的研究

Study on Monitoring Dam Deformation with GPS Positioning

对利用ＧＰＳ定位技术进行大坝变形观测的可能性进行了研究，对影响ＧＰＳ精密定位精度的各种因素进行了分析和讨论提出了为满足大坝变形观测的精度要求应采取的措施和方法，并进行了模拟试验，试验结果表明采取适当措施后ＧＰＳ定位是能满足大坝变形观测的精度要求的．

In this paper, the POssibility of monitoring dam deformation with GPS POSitioning isstudied, and the factors affecting the accuracy of GPS petitioning are analysed and discussed. Themeasures and ways which should be adopted in dam deformation observation are presented to satisfy the needed accuracy. A simulating test has been made. The result of the test indicates that theGPS positioning can satisfy the accuracy requtements of dam deformation observation, if propermeasures and ways are adopted.
