摘要
根据小波变换的特征,对四川二滩大坝变形监测数据进行了消噪和不同频带分离,达到了平滑滤波的目的,对变形体变形作出了几何分析和物理解释。研究结果表明,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。
According to characteristics of wavelet transform , this paper made use of it to divide frequency and eliminate noise for observed data, on the basis of this, we get reasonably quantitative analysis and qualitative explanation for the construction. The results show that wavelet transform is effective and suited to the processing of deformation monitoring.
