Study on Drifting Distance and Collision Force of Floating Vessels Run on Apron by Tsunami

The present paper describes the application of the moving particle semi-implicit method to a prediction of drifting distance and collision force of floating vessels run on wharf by tsunami. Effectiveness of the application is verified. Solitary wave have been applied to simulated tsunamis in numerical simulation and to the model experiments. A pontoon type floating body has been used to floating structures in numerical simulations using the MPS method. The present numerical results have been compared with the experimental results and the applicability of MPS method has been discussed. Further, after the running on wharf by tsunami, the characteristics of drifting distance and collision force of floating body on the wharf have been discussed.
