摘要:
为研究南水北调金湖站抽调水对宝应湖围网养殖区水动力的影响，通过利用 MIKE21软件构建金湖站站下水域二维水动力模型，设立了设计工况、正常运行工况及多种对比工况，分析站下水域在不同抽水规模、不同初始水位条件下的流速变化情况。通过分析模拟结果可得，抽水引起围网区出现瞬时流速峰值。其中，靠近泵站的围网区口门处流速峰值最大，且抽水规模越大，初始水位越低，围网区瞬时流速峰值越大；通过模拟优化后的泵站运行方案，得出分段开机抽水可有效削弱围网区流速激增的现象。
Abstract:
In order to study the impact of water pumping from Jinhu Station of the South-to-North Water Diversion Project on the hydrodynamics of the purse seine aquaculture area in Baoying Lake, a two-dimensional hydrodynamic model of the water area downstream of Jinhu Station was made by using MIKE21 software. The downstream area of the station was analyzed under various operation schemes with different pumping scales and different initial water levels. By comparing the simulation results, it can be obtained that pumping caused instantaneous flow velocity peaks in the purse seine aquaculture area. Among them, the peak flow velocity at the entrance of the purse seine area close to the pumping station is the largest, and the instantaneous flow velocity peak in the purse seine area is larger when the pumping scale is larger or the initial water level is lower. By simulating the optimized pumping station operation scheme, it can be obtained that turning on the pumping machines at regular intervals instead of turning on all at the same time can effectively weaken the rapid increase in flow velocity in the fence area.
