摘要
将大坝监测的数据序列视为一串由不同频率组成的数字信号,利用多分辨分析提出了基于小波分析提取大坝监测数据效应分量的方法,给出了该法的的基本原理和计算思路。以棉花滩碾压混凝土坝水平位移监测数据为例,分离结果表明,小波变换在分离效应分量具有较好的实用性和操作性。
Taking the series of dam safty monitoring values as one of digitals,which is composed of different frequencies.abstracting response component of dam observation data based on wavelet analysis is performed using multiresolution analysis,and the basic principles and the calculation of idea of the method are given. Taking horizontal displacement of a roller compacted concrete dam monitoring data as an example.the separation results show that wavelet analysis is practical and effective in data processing for dam safty monitoring.
