摘要
通过气象、水文、泥沙等实测资料和汇总已有研究成果,分析了滨州港海区水动力、泥沙环境和航道淤积情况特征。研究结果表明:(1)滨州港附近海域属不正规半日潮海区,潮流属于规则半日潮流,基本呈往复流形式运动;(2)波浪以风浪为主,常浪向ENE,强浪向ENE;(3)滨州港位于粉沙质海岸,正常天气条件下水体含沙浓度较低,大风天泥沙运动活跃,含沙量较高,-6 m等深线处底层含沙量可达为5 kg/m3以上;(4)滨州港外航道淤积的主要泥源为风浪和潮流作用下滩面泥沙的搬运输移,2015年11月寒潮大风滨州港外航道平均淤积厚度约1.8 m,最大淤厚达4.0 m。
Based on the measured data of meteorological,hydrological and sediment data and the summary ofthe existing research results,the characteristics of hydrodynamics,sediment environment and channel siltation inBinzhou port were analyzed. The results show that the tide near Binzhou port is irregular semidiurnal tide,currentis regular semidiurnal current and reciprocating flow. Wind wave is the dominant wave pattern,main direction ofwaves is ENE and direction of strong waves is ENE. Bizhou port is located in the silty coast. The suspended sedi-ment concentration is low under calm weather and is high under strong wind weather. The concentration near bedcan reach to above 5 kg/m3at-6 m. The main source of channel siltation is the sediment transport under waves andcurrent. The averaged deposition thickness of the outer channel is 1.8 m and the maximum thickness is 4 m.
