摘要
在波浪槽中进行了三个园柱的单排桩群和4×4个园柱的桩群所受波浪作用力的实验研究。单排桩的波浪入射角为0°、45°和90°:4×4桩群的波浪入射角为0°和45°。通过研究给出了三个园柱的单排桩群和4×4桩群的总干扰系数以及各个组成桩的干扰系数随Keulegan-Carpenter数、相对桩距和波浪入射角的变化;找出了桩群中承受最大波浪作用力的组成桩;提出了遮蔽效应、整体效应、射流效应和抑制效应等四种效应以解释所得到的结果。
Wave forces on rectilinear arrays of three cylinders and 4×4 cylinders were tested in a wave tank The wave incident angles were 0°,45° and 90° for the arrays of three cylinders and 0° and 45° for the arrays of 4×4 cyliders.Total interference coefficients of arrays and interference coefficients of component cylinders of the arrays are obtained.These coefficients vary with the Keulegan-Carpenter number,relative cylinder spacing and wave incident angle.The component cylinder bearing the maximum wave force in the array has been found.Four effects,i.e.,shielding effect,solidification effect,jet effect and suppression effect are proposed by the authors to explain me results obtained.
