Abstract

Stability analysis of ground motion topography effect is one of the important topics in geotechnical and earthquake engineering. In order to solve the major problems in seismic effect signals of colluvium accumulation slope in different target positions: weak echo signal and large dynamic range, we proposed an improved wavelet denoising analysis method. Through denoising experiments, we calculated signal-noise ratio and root mean square error, which could be used as denoising evaluation index. In this way, we obtained
optimal wavelet basis, decomposition scale, and threshold allocation rules and achieved the better wave filtering effect and the increased signal-noise ratio.
