Denoising in Steel Structural Impulsive Vibration Signal Based on Independent Component Analysis Junhong Cao 1,a, Zhuobin Wei 1,b 1Naval University of Engineering, China aEmail:caojunhong735@126.com bEmail:weizhuobin@eyou.com Key words: Independent component analysis，Steel structure，Impulsive vibration，Denoising Abstract: The analysis of structure vibration signals is influenced by noise mixed in the signals.
Furthermore, noise, rebounded vibrations, and material intrinsic vibration made the case more complicated and so more difficult for the ICA algorithm to separate.

Although in geotechnical engineering it is common the use of the water content, w, most of the equations are presented in terms of volumetric water content, q.
Choosing an adequate numerical model to fit the experimental data it is possible to obtain a representative SWCC curve for the material, detecting phenomena like the hysteretic behaviour and the small differences between wetting and drying paths.
