日照港深水航道泥沙运移及航道选址研究

Study on Sediment Transportation and Sea-route Site Selection in Rizhao Harbor

使用SP2100波潮仪和ADCP海流计等多种先进仪器在台风季节进行了波浪、海流和潮汐观测,在取得大量现场观测子料基础上,结合长期的岸站资料对该海域的水文特征及水动力特征进行了系统综合分析,通过2002年对日照港深水航道海域含沙量和水深测量等成果,进行断面输沙、航道冲淤量及航道海域泥沙数值模拟等方面的计算,并采用POM模式。选择了几种有代表性的风浪情况,分别对港口附近海域进行了“波浪掀沙、潮流输沙和海底演变”的数值模拟。通过上述方法,对1998年12月竣工的-11m水深的航道的淤积状况进行了探讨,并推荐方案1为深水航道的首选方案,方案5居次。

Synthetical systemic analysis of hydrologic and dynamic conditions in the sea area are carried out based on the long-term data by coast stations and the field data obtained by using tide, current and wave gauges (model: SeaPac 2100) and Acoustic Doppler Current Profiler in the season of typhoon. With the data of sand content in the sea-route water and hydrographic survey in 2002, calculations for sand transportation in the sea-route area, sea-route alluvial quantity and so on are carried out. Moreover, the Princeton Ocean Model is adopted for numerical modeling on typical waves and current effects on sediment transportation and bottom evolvement around the harbor. With all the methods above, discussion is carried out on the alluvial condition of sea-route of -11m completed in Dec, 1998 and Scheme 1 was preferred for deep-water sea-route.
