基于小波分析的GPS大坝变形监测数据处理

Processing to GPS deformation monitoring data of dam based on wavelet analysis

本文结合某大坝GPS变形监测点的实测数据,利用小波分析技术对其进行了降噪和不同频带的分离,达到了去除噪声的效果,使其变形规律显得更加明显、直观。同时对大坝一监测点的径向形变量做了几何分析,从而为决策部门提供了参考依据。

Using GPS deformation monitoring data of a dam,wavelet analysis techniques to noise reduction and separation of the different frequency bands were conducted.The noise reduction effects are good with more obvious,intuitive characteristics.Geometric analysis of the radial deformation of the dam monitoring points was also performed so as to provide reference for the decision-making departments.
