摘要
根据小波变换方法能充分突出问题某些方面的特征,基于变形监测数据列特点,将小波变换应用于变形监测领域,即利用小波变换对变形监测数据进行降噪处理和不同频带分离,使数据列平滑以达到滤波的目的,并在此基础上合理地对变形体变形作出几何分析和物理解释。结果表明, 在变形监测数据处理分析中小波变换是一种有效的分析方法,具有一定的理论价值和应用价值。
Wavelet transformation can fully reflect the characteristics of problems under discussion, so it is applied to the domain of deformation measurement in this paper. According to the characteristics of wavelet transformation, wavelet transformation is adopted to divide frequency and eliminate noise for observed data. On such a basis, quantitative analysis and qualitative explanation for the construction are made hereafter. Results show that wavelet transformation is effective in the processing of monitored deformation data. It is of great theoretical and practical value.
