摘要
利用多分辨分析,提出了大坝变形观测数据趋势分量提取的小波分析方法,给出了该方法的计算思路,并通过工程实例验证了该方法的有效性.经实例验证表明,趋势分量可用于判断大坝变形是否趋于稳定,其作用与时效分量相同,趋势分量比时效分量更能反映大坝的工作性态.
Abstracting trend component of dam observation data based on wavelet analysis is performed using multiresolution analysis. This method is proved to be effective through an example. The example shows that trend component can be used to evaluate the stability of the dam displacement similar to the time effect component. But it is more reasonable than time effect component.
