摘要
针对变形监测工程中基准点的稳定性及有无基准点的情况,相应地采取不同的GPS基线网数据处理方法,分别为:自由网平差、秩亏自由网平差和自由网拟稳平差。试验表明,根据基准点的情况选用不同的方法能够反映出监测点的真实位移量,更适合实际工程中GPS监测网的数据处理。
According to the stability of the datum point and whether there are datum points in real project, different methods are chosen to process the GPS base network, such as adjustment of free network, rank defect network adjustment and imitative stable adjustment of free network. Results show that choosing suitable method according to the situation of the datum point can reflect the true displacement,and is proper for the data processing of GPS monitoring network.
