Research on Date Preprocessing Method for 3D Deformation Field Data in Subway Tunnel Monitoring

获得实时准确的变形场数据是保障地铁隧道运营顺利进行的重要步骤,受仪器设备故障、复杂多变的外界环境、人为失误等因素影响,变形场数据中存在数据缺失,会造成一定的安全隐患。为此,文章提出一种地铁隧道监测三维变形场数据预处理方法,用于填补缺失数据,并通过填补实际地铁隧道缺失数据验证了该方法的可行性,为地铁隧道变形场数据预处理提供了参考。

Obtaining real-time and accurate deformation field data is an important step to ensure the smooth operation of subway tunnels.Affected by equipment failure,complex and changeable external environment,human error and other factors,there are data missing in the deformation field data,which will cause certain security risks.Therefore,this paper proposes a data preprocessing method for three-dimensional deformation field of subway tunnel monitoring,which is used to fill the missing data.The feasibility of this method is verified by filling the missing data of the actual subway tunnel,which provides a reference for the data preprocessing of subway tunnel deformation field.
