In this paper, a stratigraphic profiling approach is proposed based on the soil behavior type index I c 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 I c 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 I c 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 (FFT), the computation is very fast. Case studies show that the WTMM method is effective for the detection of change points in the I c profile. It is also capable of detecting thin soil layers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
