从京唐港大风期骤淤浅议粉沙质海岸建港布置和航道选线

选用已有资料,使用了大风期航道骤淤的概化模型BEDMUD,对京唐港2003年10月的大风进行航道骤淤后报,比对后报结果与实测值,说明该模型是实用可信的,并阐明了已建挡沙堤的作用;根据计算,说明淤积的原因;根据淤积原因并参考国外一些港口建设经验,讨论今后类似粉沙质海岸的港域和航道布置原则。这是一项非生产任务的探索,目的是积累经验并进行学术和工程技术方面的讨论。

Discussion on the Layout of Port and Channel to be Constructed in Silty Coasts——From the point of rapid siltation occurrence at the approach channel of Jingtang Port

Hind cast of rapid siltation at the approach channel of Jintang Port in the gale climate of November in 2003 has been conducted with the obtained data and schematic model developed by first author; the impact of dikes coun-termeasure wave and sediment are demonstrated; according to the calculation result, we explain the causes of rapid siltation at the approach channel of Jintang Port and discuss the principles for layout and design of port and channel to be constructed in similar silty coasts. This is an exploring work, not task; its aim is for absorbing experience and dis-cussing some problems from view of academic and engineering. Some suggestion has been proposed. Good calibrations of using the schematic model to compute the rapid siltation at Jingtang Port was reasonably and practically succeed.
