Abstract

PIV (Particle Image Velocimetry) is a method for detailed motion analysis of fluid velocity. The aim of this study is to examine the applicability of PIV to slope failures. The example was the slope failure occurred in Koyae region, Miyazaki Pref., Japan, captured on VHS videotape. In order to raise analysis accuracy, parameter setup, preprocessing and the post processing methods of the images were examined. The results analyzed by the present PIV method correspond with previous researches. However, some problems still remain in terms of full practical use, and we also suggest a solution method.
Key words:PIV, PTV, slope failure, motion analysis
