天津滨海新区地面沉降多维立体监测分析方法研究

Study on multi-dimensional monitoring analysis method of land subsidence in Binhai New Area, Tianjin

针对目前地面沉降监测中单一监测结果造成沉降区域划分和土层变形情况掌握不精确的问题,提出了采用多维立体监测分析的方法,同步分析区域内水位监测井的水位数据、水准监测点的沉降数据及InSAR雷达监测的沉降数据,并对重点研究区域采用一孔多标的监测方法分析土层的变形特征。实现了从定性分析区域沉降特征到定量分析土层变形特征的转变,为滨海新区的地面沉降防治走向精细化管理提供了一种研究思路。

In view of the imprecise division of subsidence area and soil deformation caused by single monitoring result in current land subsidence monitoring, a multi-dimensional and three-dimensional monitoring-analysis method is proposed which synchronously analyze the water level data, the subsidence data of level-monitoring points and InSAR radar in the region. And the deformation characteristics of soil layers in serious areas are analyzed by the monitoring method of one-hole and multi-targets. It realizes the transformation from qualitative analysis of regional subsidence characteristics to quantitative analysis of soil deformation characteristics. It provides a research approach on delicacy management to prevent and control the land subsidence in Binhai New Area.
