TOPOGRAPHICAL CHANGE AROUND MULTIPLE LARGE CYLINDRICAL STRUCTURES UNDER WAVE ACTIONS

[摘要] This paper is aimed to investigate theoretically and experimentally the topographical change and the local scouring around multiple large cylindrical structures under wave actions. It is revealed from laboratory experiments that the bottom configuration, the local scouring area and its depth around the cylindrical structures are changed largely according to the number of cylindrical structures, the structure's diameter, the incident wave angle and the sediment size. The theoretical model which developed newly is shown to predict well the topographical change around the structures.
