摘　　要：本文主要介绍GPS用于地质灾害滑坡监测的技术和方法 ,并通过在中国的四川雅安峡口滑坡示范区布设的GPS监测网的测量试验 ,证明在恶劣的观测条件下 ,GPS仍然可以用于滑坡的监测 ,并提出了在恶劣条件下提高GPS观测精度和可靠性的方法。This paper presents some GPS technologies and methods for monitoring geological disasters.And through the surveying experiment of GPS monitoring network laid on the coast demonstration area of Xiakou,Ya′an,Sichuan province,it is proved that even in bad condition for observation,GPS can still run well.In view of this,this paper also gives a reliable method to improve observation precision in case of bad conditions.
