平均间隙法在地铁沉降监测平面基准网稳定分析中的应用

摘要

In the process of subway construction , monitoring technology should be vsed throughout the whole sub-way 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 ana-lyze stability of subsidence monitoring network , inspection , to ensure the reliability of the control network to en-sure the quality of monitoring data , furthermose to real and reliable monitoring data to guide construction .%在地铁建设中，监控技术应贯穿于施工的全过程之中。以某地铁一号线一期工程施工监测为依据，通过理论分析和现场实测数据相结合的方法，对城市地铁监控中的主要沉降监测项目、内容、方法及数据处理分析进行了探讨。通过平均间隙法对沉降监测网稳定性进行分析、检验，确保控制网的可靠性，从而保证监测数据质量，以真实、可靠的监测数据来指导安全施工。
