Abstract:	摘要： In this paper, a stratigraphic profiling approach is proposed based on the soil behavior type index, Ic, obtained from the cone penetration test (CPT). The basic idea of this approach is simple: the layer boundaries can be identified as the points at which a change occurs in the Ic profile. It is shown that these change points can be easily identified using the wavelet transform modulus maxima (WTMM) method. This method is able to accurately pinpoint the locations of change points in the Ic profile and to produce graphs and plots that fit well with engineers’ methods of visualization and intuition. Moreover, by virtue of the fast Fourier transform, the computation is very fast. Case studies show that the WTMM method is effective for the detection of change points in the Ic profile. It is also capable of detecting thin soil layers. 出版者： Canadian Science Publishing 出版日期： 2015-12-01 出處： Canadian Geotechnical Journal, 2015-12, Vol.52 (12), p.1993-2007 識別號： ISSN: 0008-3674 識別號： EISSN: 1208-6010 識別號： DOI: 10.1139/cgj-2015-0027
