中文摘要：

为研究大风对金山湖水利调度过程的影响，使用 SMS 软件的 RMA2二维水动力模型，模拟了东南向45°8级大风作用下金山湖调水过程的水动力特性，并和无风作用时的水动力特性进行比较分析。结果表明：大风作用下金山湖注水过程发生明显的增水现象，换水过程增水现象较弱；大风对金山湖水流流向影响不大，增加了水流沿岸流动的趋势，增强了注水过程西部湖区的涡流现象；大风增大了金山湖的流速，入流断面和出流断面流速的增大比主湖区大。研究成果为金山湖多闸站联合调度提供了水动力学依据。

英文摘要：

To investigate the influence of strong wind on the water transfer process of Jinshan lake,we employed the RMA2 two-dimensional hydrodynamic model of Surface-water Modeling System （SMS）to simulate the hydrodynam-ic characteristic of water transfer under the action of wind （southeast direction,45°）of scale 8 and compared it with that in the absence of wind action.Results show that when there is strong wind,water level increases obviously in the water injection process,but the phenomenon is weak in the water exchange process;flow direction is not much affected by the strong wind,but the trend of water flowing along the bank intensifies and the eddy flow in the west part of the lake is more apparent in the water injection process;wind increases the flow velocity of the lake,and the increment is more obvious in the inflow section and outflow section than in the main area of the lake.The research result is a basis for the joint dispatching of multiple stations of Jinshan Lake.
