【摘要】:基于Delft3D數(shù)值模擬軟件建立渤海灣西南岸二維潮流、波浪和泥沙輸運(yùn)數(shù)學(xué)模型.運(yùn)用驗證合理的模型研究近20年的港口工程建設(shè)對渤海灣西南岸水沙動力特征的累積影響以及黃驊、濱州兩港水沙動力的相互作用.結(jié)果表明,港口工程建設(shè)使渤海灣西南岸逐漸形成3個相對獨立的海區(qū);波流耦合作用下,全潮平均含沙量分布情況基本與純潮流時相似,但量值提高近8倍.沿岸流的增強(qiáng)使含沙量等值線趨于與岸線平行,漲潮輸沙量的增加使黃驊港以西,黃驊、濱州兩港之間以及濱州港以東近岸區(qū)域的泥沙含量比例重新分配;總體看來,連片港口工程建設(shè)使渤海灣西南岸逐步達(dá)到新的輸沙平衡狀態(tài).黃驊港綜合港區(qū)與濱州港防波堤一期工程(2012年)與規(guī)劃工程(2020年)可分別削弱正常天氣、常浪天氣下港區(qū)間泥沙相互輸運(yùn)的影響.
[Abstract]:Delft3D numerical simulation software to establish the southwest coast of the Bohai Bay based on two-dimensional tidal current, wave and sediment transport mathematical model. Using the cumulative effects of port engineering construction model to study the reasonable nearly 20 years on the southwest coast of the Bohai Bay hydrodynamic characteristics as well as Huanghua, Binzhou port two interaction of water and sediment power. The results show that the port engineering the construction of the southwest coast of the Bohai Bay has gradually formed 3 relatively independent area; wave current coupling effect, similar to the whole tidal average sediment concentration distribution and the pure trend, but the value increased by nearly 8 times. The enhanced sediment contour tends to be parallel with coastline coastal current, increase the sediment. Huanghua west of Hong Kong, Huanghua, two between Binzhou port and Binzhou port east of the coastal sediment concentration ratio redistribution; overall, contiguous port engineering construction to the southwest coast of the Bohai Bay gradually reached the new transport sediment The Huanghua port comprehensive port area and the Binzhou port breakwater phase I Project (2012) and the planning project (2020) can weaken the normal weather and the influence of sediment transport in the port area.
