| 摘 要： | 由于地铁隧道结构变形监测控制网的特殊性,在变形数据处理过程中基准点稳定性判断是不容忽视的环节,通常稳定性判断是在室内数据处理时进行,为了优化变形数据处理过程,本文采用已有组合后验方差检验法进行基准点稳定性检验,并验证该方法的可靠性,在此基础上提出灵敏度的概念,即检验观测值出现多大变动时能被该方法检测出来,并测试出组合后验方差检验法的灵敏度。通过灵敏度的研究和应用可以现场进行稳定性分析,指导外业变形监测工作,提高观测结果利用率和数据处理效率。

| Abstract: | Due to the particularity of deformation monitoring control network of subway tunnel, the stability judgment of the reference points is absolutely necessary in the data processing. Stability judgment is usually included in data processing in the interior. For opti- mizing data processing of deformation monitoring, this paper adopts the existing method -- combination unit weight variance for stabili- ty judgment of the reference points. And we verify the reliability of the method. Based on this research, this paper puts forward the concept of sensitivity -- testing how changes the observed value appears can be detected. And we test this method＇s sensitivity. Through the research and application of sensitivity to do stability analysis in observing site, we can guide field deformation monitoring work and improve utilization of observation data and efficiency of data processing. |
