摘要
黄骅港位于渤海湾西南,是建在淤泥质海岸上的人工港,在特殊大风期间,即E向或ENE向6级以上的海向风延时14小时以上时,外航道的淤积量大大超过原先的预测值,且淤积物为密实、坚硬、难以疏浚的粉沙。本研究表明,这一问题产生的原因是堤头旋涡的输沙作用,卫星图像和数模证明了堤头旋涡的存在;同时还对设置垂直和平行于海岸线防波堤的两种整治方案作了讨论。
The Huanghua Harbor is a man-made harbor in the muddy beach at the southwest of the Bohai Bay. The current problem is that during gales whose wind force over Grade 6 and lasting more than 14 hours in E or ENE direction from the sea, the aggradation in the outer waterway greatly exceeds the estimate and the accretion consists of hard and close-grained fine sediments which is difficult to dredge. The study on this paper shows that the above problem is caused by sediment transport of vortex, which is verified by satellite photos and numerical model. Furthermore, two kinds of control plan were compared with each other.
