| Outline of Final Research Achievements |
This study evaluated impulive and impact loads generated by debris flow and interactive behavior of sabo dam wings by using particle method and finite element analysis. The mudflow and gravel cobble flow including large rocks are modeled by bingham fluid and particle method with fluid and rigid particles, respectively. In addition, a particle method considering the turbulent flow was developed. The impulsive and impact loads due to the debris flows were assessed by the numerical models. Sabo structures were modeled by finite elements and simulated their impact resistant performance by acting the impulsive and impact loads.
