摘    要:采用拼接网格方法,考虑闸门开度、风荷载等影响,构建了三河闸枢纽进出流二三维耦合数学模型,并对三河闸进水流态及过闸水流流态进行了模拟研究。利用实测流速与水位率定,验证了模型参数。通过对测流工况流场特征的模拟研究,发现三河闸产生偏流的最主要原因是上游左岸快活岭的阻流作用,因此提出两套快活岭切滩纠偏的工程方案。通过各方案数值试验,比较其水位横向比降、入流流速的均匀度和入流偏角均值,并综合考虑切滩工程量与纠偏效果,认为小切方案较优,该结果可为工程决策提供参考。

关 键 词:三河闸  耦合模型  拼接网格  纠偏措施

Abstract:2D-3D coupling mathematics model is used to simulate the inflow pattern of Sanhe sluice. The nested grid is applied,and the parameters are calibrated and verified by in-situ measured velocity and water level. The cause of deflecting of inflow was analyzed,which shows that the Kuaihuoling has significantly influence on inflow patten. Different rectification schemes were numerically simulated. The comparison of the standard deviation of node velocity in the cross section in front of the sluice with the averag...
Keywords:Sanhe sluice  2D-3D coupling model  nested grid  rectification measure
