【摘要】：以資料分析為基礎(chǔ),利用數(shù)學模型計算分析的手段,針對當?shù)匦D(zhuǎn)流和黏性泥沙的運動特性,從水流、泥沙角度對連云港徐圩港區(qū)港池布置方案中的口門位置、口門寬度和布置形式進行了論證。分析認為,由于岸灘坡度較緩,大風天破波帶影響范圍較廣,同時被波浪掀起的細顆粒泥沙可被潮流遠距離輸送,因此從減小泥沙回淤角度來看,港池應采用雙環(huán)抱形式,而口門應布置在連云港理論基準面高程-5 m(破波區(qū))以外,以此可以降低破波帶內(nèi)懸浮泥沙進入港池和外航道的可能性。同時分析論證認為,初期方案口門不宜過窄,以減小口門的水流強度;口門采用"八字"型布置,可以提高口門航道船舶航行和近口門泊位靠離泊的安全性。上述港池布置方案建議已被設(shè)計院接受并在實施方案中體現(xiàn),可供類似港口布置方案借鑒參考。
[Abstract]:On the basis of data analysis, by means of mathematical model calculation and analysis, according to the motion characteristics of local rotational flow and viscous sediment, from the point of view of water flow and sediment, the entrance position in the layout of harbor pool in Xuxu Port area of Lianyungang is analyzed. The width and layout of the gate are demonstrated. The analysis shows that because of the gentle slope of the shoreline, the wide influence of the windy wave breaking zone and the fact that the fine sediment caused by the wave can be transported by the tidal current at a long distance, the harbor pool should adopt the form of double entrainment from the point of view of reducing the silt back to silt. The entrance should be arranged outside the theoretical datum elevation of Lianyungang (breaking zone), so as to reduce the possibility of suspended sediment entering the harbor pool and the outer channel in the broken wave zone. At the same time, it is concluded that the initial scheme should not be too narrow in order to reduce the flow intensity of the entrance, and the safety of navigation and berthing of the berth near the gate can be improved by adopting the "eight characters" arrangement of the entrance. The above proposal has been accepted by the design institute and reflected in the implementation plan, which can be used as reference for similar port layout scheme.
