- 通过冀东南堡油田4号构造路岛工程整体物理模型试验,研究该路岛工程建造后与周边海域潮流的相互影响。试验结果表明,人工岛建成后仅改变人工岛附近的东、西坑坨浅滩局部水流形态,滩面平均水流强度减小13%～15%,人工岛对涨落潮滩面水流的漫滩归槽有一定的引导和归顺作用,对曹妃甸海域宏观水流强度、流态影响较小。考虑到波浪长期作用,建议4-1号人工岛南侧和引堤前岸滩的底床防护范围为50～60 m,人工岛南岸线东西两端防护范围适当增加。
Physical model tests are performed to study the influences of road and artificial island that will be built at the geological structure No.4 of Nanpu Oilfield on the tidal currents in nearby sea areas.The test results show that after the completion of the artificial island,the tidal currents in the shoals of Dongkengtuo and Xikengtuo near the artificial island change locally;And the surface flow intensity has a decrease of 13% ～ 15%;The artificial island has certain guiding action on the return of flooding and ebbing tides to the channel;It has smaller influences on the macroscopic flow intensity and flow regime in Caofeidian sea area.Considering the long-term action of periodic waves,it is suggested that the protection ranges of the seabed of the shoals in front of the south side of No.4-1 artificial island and the guide jetty should be 50 ～ 60 m,and the protection ranges should be appropriately increased at the eastern and western ends of the southern bank of the artificial island.2011,4(4): 18-21 收稿日期：2010-10-29分类号：P751作者简介：李凯双(1969-),男,河北唐山人,高级工程师,1990年毕业于西安石油学院,现从事油田海洋工程基本建设管理工作.参考文献：
