摘　　要：在保证精度的前提下,试验使用高精度GPS大地高进行垂向变形监测,研究垂向变形监测中数据处理的模型、方法,用国家等级水准对GPS大地高监测结果进行检验。结果表明:在平原地区超长水坝变形监测中,可以用GPS测高来代替几何水准测量对坝区的垂直位移变形进行监测。The author uses high-precision GPS geodetic elevation to monitor vertical deformation in the premise of ensuring the accuracy,studies on the models and methods of data processing in vertical Deformation Monitoring,and uses National level standards to test the results of GPS geodetic monitoring.The results show that it is possible to use GPS instead of geometric leveling to monitor the vertical displacement deformation of dam in deformation monitoring of the long dams in plains.
