提出了基于聚类分析方法确定全球定位系统(GPS)变形监测网拟稳点稳定性的数学模型, 用以解决GPS变形监测网平差的基准问题。结合某大坝GPS变形监测网的3期观测数据,对 GPS变形监测网拟稳点的相对稳定性进行了聚类分析。计算结果表明,提出的数学模型是可行和可靠的。

A mathematical model based on clustering analysis for testing the stability of quasi-stable points is put forward to solve the datum problem of GPS deformation monitoring network adjustment. With the data of three observation periods from the GPS deformation monitoring network of a dam, the clustering analysis is conducted on the relative stability of quasi-stable points of the network. The calculation results show that the mathematical model is feasible and reliable.
