The Application of Mean Spacing Method in the Analysis Stability of Subsidence Monitoring Plane Datum Netsubway

In the process of subway construction,monitoring technology should be vsed throughout the whole subway construction. In this paper,based on the first phase of construction monitoring,main subsidence monitoring of urban subway monitoring project,content,method and the analysis of data processing are discussed through the method of combining the theoretical analysis and field measured data. Mean spacing method is aimed to analyze stability of subsidence monitoring network,inspection,to ensure the reliability of the control network to ensure the quality of monitoring data,furthermose to real and reliable monitoring data to guide construction.
