摘　　要：全球定位系统(GPS)是一种全天候、高精度的连续定位系统,它以速度快、方法灵活多样、操作简便等优势被广泛应用于工程测量和变形监测中。结合水厂铁矿GPS边坡变形监测实例,对GPS监测网的星历预报、基线向量平差计算、网平差计算、结果及残差不确定度进行了细致分析研究,以验证GPS技术在边坡变形监测中的可靠性和精度。As an all-weather and high precision continuous positioning system, the global positioning system（GPS） is widely applied to engineering measurement and deformation monitoring because of its speediness, agility and operability. In combination with practice, occupation planning, baseline vector calculating, network adjustment results and residential uncertainty of the deformation monitoring network are analyzed and studied in detail. The reliability and accuracy of GPS monitoring for slope deformation are verified.
