DEVELOPMENT OF MPM-MPS COUPLING METHOD AND NUMERICAL ANALYSIS OF SCOURING OF EMBANKMENT CAUSED BY OVERFLOW

抄録

In the 2011 earthquake off the Pacific coast of Tohoku, tsunami-induced overflow had resulted in the scouring of embankments. A material point method–moving particle simulation coupling method was de veloped to predict the extent of such scouring. The effectiveness of the developed method was verified through reproduction analyses of the scouring of embankment caused by tsunami-induced overflow. Consequently, the developed coupling method could simulate the process and extent of scouring.
