摘　　要：提出一种无稳定基准的变形监测网数据处理与稳定性分析的方法与流程,解决了多期监测数据中网型一致性和基准一致性问题。利用平均间隙法原理,判断监测网中点的稳定性,进而确定变形模型,并对该模型进行灵敏度分析。通过计算实例说明了其可行性和优越性。An appropriate method and flow for data processing and stability analysis of deformation monitoring network with no stable datum is proposed.So the consistency of graphics and datum of observational data in several periods can be achieved.Futhermore,the point＇s stability of the network can be judged by use of the method of mean gap and we will obtain the deformation model,and analyze the model＇s sensitivity.A computational example shows the feasibility and superiority of the method.
