摘　　要：本文从理论上分析了ＧＰＳ测量能达到的精度，提出了ＧＰＳ在大坝变形观测中的技术要求和注意事项，研究了数据处理与形变分析方法，通过测试证明，ＧＰＳ测量可以解决土石坝外部变形观测视准线法因精度不高而处于停止观测的状态。This paper analyzed the precision that GPS surveying could measure and made technical requirements for GPS surveying at the dam deformation. The method for data processing and deformation analysis was also discussed. Through the test, the problem that the collimation line surveying method for earthrock dam external deformation observation can be solved.
