| Summary | Sediments produced by slope failures can be fluidized and run down over long distance in some case. Recently, the cases that sediments produced by slope failures on over-30m-high long slopes are fluidized are attracting attention. The mechanism of such phenomenon is not fully clarified. And traditional prevention facilities may not be able to fully handle the fluidized sediments. In this investigation, we analyze the mechanism of fluidization of sediments produced by slope failures, in order to obtain knowledge to establish the methods for investigation, planning and designing of disaster-prevention facilities that can respond to such phenomenon. |
