常州市地表沉降观测与成果分析

从地面沉降观测的必要性出发,进行水准观测数据的处理,平差基准选定的探讨,并对常州市行政区域内历年来的水准观测数据应用时空分析,形变数字特征值及速率的非线性变化等方法,分析常州市行政区域内地面垂直位移的发展过程及特征,得出常州市区域内沉降漏斗迁移路径的变化规律,为常州市今后的地面沉降分析提供参考。最后讨论了引起地面沉降的原因,提出今后的弥补措施。

Subsidence of surface and analysis of survey data in Changzhou city

Aiming at the necessity of surface subsidence monitoring,it takes the processing of level survey data and discusses the criterion on adjustment.By the methods of spatio-temporal analysis,deformation figure and nonlinear change of velocity,it gets changes on displacement of subsidence filter in Changzhou city as a result of processing level survey data.It indicates the performance of surface displacement in vertical-plane and provides the reference for Changzhou future construction.Discussion is also made on the reasons of subsidence of surface and given the methods.
