Deformation Data of Dam Monitoring Based on Wavelet Analysis Method
OU Yang-ping · Beijing Surveying and Mapping · 2010
This paper introduces the wavelet analysis method of dam deformation monitoring data to achieve the scale decomposition of the discrete deformation data,and trend analysis of deformation.For filtering,denoising of deformation data,the characteristics analysis of decomposition level of accidental errors,and threshold selection methods were compared,indicating that the method based on wavelet transform analysis of the deformation data is an effective and feasible.
