Analysis of Tunnel Monitoring Results Based on the Modulus Maxima Method of Wavelet Transform
Publication: Geo-China 2016
Abstract
In recent years, the theory and method of wavelet analysis is widely used in signal processing, pattern recognition, data compression, image processing, and quantum physics. Compared with modulus maxima, wavelet packet decomposition and coefficient shrinkage de-noising method of wavelet transform, their advantages and disadvantages are analysed and summarized, and their respective scopes are obtained. The Noissin chosen as the original signal with noise is analysed and de-noised by the modulus maxima method of wavelet transform, meanwhile the usage conditions and key computing parameters are also obtained. Finally, the modulus maxima method of wavelet transform are successfully adopted to de-noised the monitoring results of shield tunnel, the data revised are reliably provided for tunnel healthy diagnosis.
