摘要
小尺度的群桩结构在海洋工程建筑物中应用广泛,其在波浪作用下产生的群桩效应也被国内外学者所关注,但是目前有关群桩效应的研究多限于较少桩柱。基于物理模型实验,对不规则波作用下,9桩串列群桩中各桩所受正向力、横向力进行了研究,结合对应波浪作用下孤立桩所受波浪力,分析了正向力和横向力群桩系数K_(G,1/3)、K_(GL,1/3)随相对桩距S/D和KC_(1/3)数变化的规律,并对比了群桩中各桩上群桩系数的区别。
Small scale pile groups are widely used in ocean engineering.The pile group effect under wave action has been focused by scholars all over the world.However,the pile number is limited at the present studies associated with pile groups.The inline and transverse force were experimentally studied for a 9-tandem-pile group structure under the action of irregular waves.Combining with the forces on a single pile,the variation of the parameters KG,1/3,KGL,1/3 with relative pile distance S/D and KC1/3 number were analyzed.The group effects of each pile in the group structure were compared.
