【摘要】：根据滨州港区水深、水文泥沙等现场观测资料,分析港区水动力变化规律和工程海域海床冲淤态势,论述外航道骤淤及可挖性。结果显示:大风淤积将成为滨州港建港后的重点和难点;在航道尺度和走向与黄骅港基本相同的情况下,滨州港建成后外航道淤积严重程度将超过黄骅港;滨州港外航道挖泥具有一定难度,且恶劣天气情况出现后,-6 m等深线外一定范围出现"铁板砂"现象的可能性极大。根据预判,滨州港回淤物粒径粗于黄骅港,且黏土含量小于黄骅港,可预计外航道的开挖(或清淤)难度较黄骅港大。
[Abstract]:Based on the field observation data of water depth, hydrology and sediment in Binzhou port area, the hydrodynamic variation law of port area and the situation of sea bed scouring and silting in engineering sea area are analyzed, and the sudden siltation and diggability of outer waterway are discussed. The results show that the windy siltation will become the key and difficult point after the establishment of Binzhou Port, and when the channel size and direction are basically the same as those of Huanghua Port, the degree of sedimentation in the outer waterway of Binzhou Port will be higher than that of Huanghua Port after the completion of Binzhou Port. Dredging of silt in the outer channel of Binzhou Port is difficult, and the phenomenon of "iron plate sand" appears in a certain range outside the isobath of 6 m after severe weather conditions. According to the prediction, the diameter of silt in Binzhou Port is larger than that in Huanghua Port, and the clay content is smaller than that in Huanghua Port, so it can be predicted that the excavation (or clearing of silt) of the outer channel is more difficult than that of Huanghua Port.
