Li Zhenghang; Liu Zhizhao; Wang Zemin(The College of the Earth audience and Surveying Engineering,Wahan Technical University of Surveying and Mapping)  
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.
