摘　　要：An experiment that investigates the interactions between dam-break flow and a floating box is reported in this paper.The interaction processes are described in detail,and the effects of reservoir depth,clearance between the structure and vertical wall,and structure motion on the observed interactions are discussed.Results indicate that interactions are mild if the reservoir depth is relatively small and most of the water flows through under the structure.However,as the reservoir depth increases,the interactions intensify,and overtopping and wave splashing occur.The incident wave is divided into two parts by the structure:1)a jet generated by wave impact and 2)the water flowing through under the structure.The water flowing through under the structure is the main factor influencing the motion of the structure.The phenomenon of secondary slamming is observed in all of the test cases,and the relative motion of the structure and free surface explains the occurrence of secondary slamming.
