摘 要: 为了研究监测对象的变形规律,有必要消除测量噪声得到更准确的数据,小波变换理论在数据处理方面有其特点。本文利用小波去噪的理论对监测数据进行小波变换,得到信号的高频部分,并进行去噪处理,得到了较好的效果。此方法具有一定的工程应用价值,本文提供了一个地铁工程变形监测数据处理的例子。 To study the deformation rule of the monitoring object, it is necessary to eliminate the noise for a clear data. The theory of wavelet analysis has some special characteristic in data processing. This paper apply the denoise theory to process the monitoring data, get the high frequency part of the data and do the denoise process. It achieves a good effect by this way and this method has some application values in project construction. This paper also supplies an example of subway project deformation monitoring data processing by the way of using wavelet method.
