岬角型岸线潮流泥沙特点及海洋工程问题

摘要

在一些海岛或湾口部位,岸线走向不再平直,而具有"岬角型"海岸线特点,经过这里的潮汐水流也随着边界条件的不同,具有分流(汇流)或绕流(挑流)等不同特点的流态.文章结合几个典型的港口工程研究成果,将岬角型岸线处潮流特点进行归纳分类,同时分析它们的泥沙运动特点及建设海洋工程时可能存在的问题,探讨整治工程的原则和方法等.%Some coastline parts of island or mouth of bay, the coastline direction is not straight, but with a"Cape"characteristics.So the tidal currents are of different features, such as shunt( confluence) current or bypas-sing( deflecting) current in different border conditions.In this paper, on the basis of several typical harbor engi-neering research results, the flow characteristics of cape type coastline were summarized, and the characteristics of sediment transport and the possible problems in construction of marine engineering were analyzed to explore the principles and methods of regulation project.
