EVALUATION OF EROSION RESISTANCE PERFORMANCE OF RIVER LEVEE USING MULTI PARTICULATE CRITICAL VELOCITY

Abstract

In this paper, we performed the investigation on application of multi particulate critical velocity with laboratory test and numerical analysis. From the experimental results of Kutara and Yoshioka , the maximum vertical velocity was calculated using numerical analysis. As a result, it was clarified that even when the horizontal flow is dominant, it is made clear that the conditions of seepage failure caused by multiparticulate critical velocity can be applied. Furthermore, instead of the effective stress, the “particle effective force” was proposed by multiparticulate critical velocity in order to simulate the particle effective force at the time of seepage failure.
