摘要:
在实测水文、地形和闸涵枢纽资料的基础上，建立了包含洪泽湖及主要出入湖通道在内的大范围二维水流数学模型，对洪泽湖中低水位下(13.0～14.5 m)湖区水流特性、分流特性和出湖段局部水动力特征等进行了计算与分析，揭示了洪泽湖泄洪不畅的原因。结果表明，湖区主流在南侧由淮河口大幅摆弯至三河闸入江，呈明显的吞吐之势; 随入湖流量的增加和洪泽湖水位的不断抬高，南北侧分流线逐渐北移，经北侧二河闸及入海水道的泄洪流量占比有所加大，而出湖段水面比降整体有所减小; 北侧出湖段二河闸上游引河的河槽狭小，形成卡口区，在中低水位期大幅限制了洪泽湖北侧的泄洪能力。
Abstract:
On the basis of the measured hydrology, topography and sluice and culvert pivot data, a large-scale two-dimensional mathematical model of water flow including Hongze Lake and the main access to the lake was established. The calculation and analysis of the water flow characteristics, diversion characteristics and local hydrodynamic characteristics of the lake area revealed the reasons for the poor flood discharge of Hongze Lake under low water level(13.0～14.5 m)characteristics revealed the Hongze Lake flood and the cause of the poor. The results showed that the mainstream of the lake area swung sharply from the mouth of the Huaihe River to the Sanhe sluice into the river, showing an obvious trend of throughput; with the increase of the inflow into the lake and the continuous elevation of the water level of Hongze Lake, the north south diversion line gradually shifted northward. The proportion of flood discharge through the Erhe Sluice on the north side and the water inlet channel had increased, while the water surface drop of the lake outlet section had decreased overall. The channel of the upper reaches of the Erhe Sluice on the north side of the lake outlet was narrow, forming a bayonet in the middle and low water level periods, the flood discharge capacity on the north side of Hongze Lake was greatly restricted.
