摘　　要：GPS快速定位技术在现代地质灾害预防和治理中正在发挥越来越显著的作用。本文首先对滑坡监测精度的计算方法、影响因素进行了讨论,并对滑坡级别、滑坡速度与监测精度要求的关系进行了归纳。然后对当前主流GPS快速定位技术的类型、原理及特点进行了总结和阐述。最后通过三阶段的滑坡动态实时变形监测实验,对GPS-RTK技术的精度和可靠性进行了探讨。结果表明:GPS-RTK技术在滑坡灾害动态监测方面具有技术可靠性,能够用于对4级以上的滑坡灾害进行监测。GPS rapid positioning technology plays a more and more significant role in modern geological disaster prevention and control. In the paper, the calculation method and influence factors of landslide monitoring precision are firstly discussed. The relationship among landslide level, landslide speed and monitoring accuracy requirement is concluded. Then, the types, principles and characteristics of current mainstream GPS rapid positioning technology are summarized and described. Finally, the precision and reliability of GPS-RTK technology are discussed through three-stage landslide dynamic real-time deformation monitoring experiment. The results show that GPS-RTK technology has technical reliability in the aspect of landslide disaster dynamic monitoring, which can be used for monitoring landslide disaster higher than level IV.
