Application of wavelet analysis to noise removal for slope's displacement monitoring dates
Tian Binpeng · 2007
Undulation in displacement monitoring curve of slope both reflect abrupt changes which nature and manpower bring about and reflect influence of ambient noise.It's important to eliminating the noise of slope's displacement monitoring for improve veracity of slope stability evaluation.As a new mathematics utility,wavelet analysis have characteristic of multiresolution.There are abroad applications in eliminating noise of signal.In this paper,wavelet analysis is used to study the methods for eliminating the noise of slope's displacement monitoring dates.The nonlinear wavelet threshold is used for eliminating noise of displacement monitoring dates in Xi-Pan highway k132 slope and 318 national road k2791 slope.The results show this method is effective.
