摘　　要：文章首先分析、论证了应用GPS定位技术监测地面沉降的理论依据,随后,介绍了实验研究方案和实际监测 结果。通过比较GPS和精密水准所获得各个监测点的地面沉降量,以及两种不同方法获得地面沉降曲面的 一致性,得出GPS沉降监测在一般监测环境下可能达到的精度。This paper demonstrates the theoretical basis of land subsidece measurements using GPS, the results of a typical study area are illustrated afterwards. Through comparison of the value extracted by conventional precision leveling with the one extracted by GPS, coherence to gain subsidence curve between both methods is summed up. The accuracy of GPS to monitor subsidence under normal condition is discussed in the end.
