海南省东水港建港工程地貌研究

Study on Port Engineering Geomorphology of Dong Shui Port Hainan Province

分析了东水港动力地貌及沿岸输沙特征，结合东水湾潮汐汊道形成的历史过程，利用各种判据衡量了潮汐汊道的稳定性，得出目前汊道过小的口门已使汊道内外潮波传递受阻，在自然状况下，东水港沙咀——泻湖型潮汐汊道正趋于封闭的结论．利用该潮汐汊道建港的关键是扩大并固定口门和拦截沿岸输沙．

This paper analyses Characteristics of dynamic geomorphology and sand transportation along coast of Dong Shui Port;Combines history process of formation of this tidal inlet; basing on some parameters,judges the stability of this tidal inlet. The conclusion is that the entrana of tidal inlet is too narrow,it Festricts the transmion of tidal wave on natural condition, the tidal inlet of sandspit-lagoon Dong Shui Port in tending to be sealed. The important measure of using this tidal inlet to construct port is to enlarge and fix the entrance and to intercept sand transportation along coast. The valid of sand-blocking dike in the overall plan of Dong Shui Port is 50～75 years.
