| Research Abstract |
This study proposed the numerical tool for verification of impact performance of Sabo structures using solid and liquid particles. The impulsive load caused by the surge debris flow and deformation of the Sabo structures have been analyzed. In the numerical simulation of the debris flow, the discrete element method(DEM) was introduced in cooperation with the original particle method developed for fluid simulation. The surge formation of the debris flow and the impulsive load have been reproduced by the proposed method. The coupling analysis between the proposed debris flow model and Sabo structures has been proposed and validated by comparison with experimental result.
