摘　　要：利用三峡库区秭归香溪-野猫面段10个GPS监测点的两期(2005—2007年)观测数据,采用参数约束平差方法分别计算出观测网两期的经典平差、拟稳平差和自由网平差结果,获得了3种平差方案下两期观测的形变位移,并对监测点稳定性作了初步分析。Two sessions of GPS observations of ten GPS monitoring stations located at the strong landslip i. e. Xiangxi-Yemaomian zone in Zigui region of Three Gorges from 2005 to 2007, were calculated by use of three schemes of parameter constrain adjustment method including classic adjustment, quasi-stable adjustment and adjustment of freedom network and two sessions of displacement were obtained. At last, the stability of these monitoring points are discussed.
