Application of the theory of wavelet analysis and the distribution of noise on the monitoring data of project

TANG Gui-wen①,JIANG Heng-biao①,ZUO Jian-zhang②(① Guangdong University of Technology Faculty of Construction,Guangzhou 510006,China;② Chinese Academy of Surveying & Mapping Geo-Vision Technology Company Limited,Beijing 100037,China)  
To study the deformation rule of the monitoring object,it is necessary to eliminate the noise for a clear data.The theory of wavelet analysis has some special characteristic in data processing.This paper apply the denoise theory to process the monitoring data,get the high frequency part of the data and do the denoise process.It achieves a good effect by this way and this method has some application values in project construction.This paper also supplies an example of subway project deformation monitoring data processing by the way of using wavelet method.
