Abstract：Two sessions of GPS observations of ten GPS monitoring stations located at the strong landslip i.e. XiangxiYemaomian 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, quasistable adjustment and adjustment of freedom network and two sessions of displacement were obtained.At last,the stability of these monitoring points are discussed.
