On effects of hydrodynamic interaction on wave forces on pile arrays of multiple rows
-
Abstract: Much attentions have been paid on the study of hydrodynamic interaction between multiple objects which is known as an important factor in the design and study of super-large offshore structures.A systematic study has been carried out on the interaction effects of three-dimensional wave forces on vertical pile arrays by using the wave source distribution method.Not only can the properties of hydrodynamic interaction of single row piles be got,but also some new discoveries are found for the pile arrays of multiple rows.It is found that the shield effect of multiple rows is larger than single one.There is a sensitive wave frequency range in which the variation of the wave forces will probably much larger than those in the other frequency range.The mechanical characteristics for the matrix-like pile arrays are different from those for the staggered pile arrays.Those discoveries may give important guidance to the design of the super-large offshore structures.
