摘要:
通过构建太湖流域北部一维、二维耦合的河湖水动力数学模型，模拟并分析了新孟河延伸拓浚工程运南段主要无闸控支河设控前后对引水沿线河道和滆湖水动力的影响。结果表明，新孟河运南段支河口门设控下，引水后运南段河道水位、流速将明显上升，经北干河东侧入滆湖流量有所增加，但支河闸控有利于北干河西侧分流比升高，支河口门东侧闸控将导致滆湖北部水体交换能力降低、水动力有所减弱，滆湖东侧出湖河道流量受新孟河运南段支河闸控的影响较小。为提高新孟河工程引水效益，探讨提出了支河闸控方案在引水期、非引水期和应急排水期等时期的实施建议，为新孟河工程运行及优化调度提供一定的参考。
Abstract:
By constructing a one-dimensional and two-dimensional coupled river lake hydrodynamic mathematical model in the north of the Taihu Lake basin, this paper simulates and analyzes the influence of the main non gate-controlled tributaries in the southern section of the Xinmeng River extension and dredging project on the hydrodynamic forces of the rivers and Gehu Lake along the water diversion line before and after the gate control is set. The results show that under the control of the estuary gate of the southern branch of the Xinmeng River, the water level and flow velocity of the southern section of the river will significantly increase after water diversion, and the flow into Gehu Lake will increase on the east side of the northern main river. However, the gate control of the branch river is conducive to the increase of the diversion ratio on the west side of the northern main river. The gate control on the east side of the estuary gate of the branch river will lead to a decrease in the water exchange capacity and a weakening of hydrodynamic forces in the northern part of Gehu Lake. The flow of the river on the east side of Gehu Lake is less affected by the gate control of the southern branch river of the Xinmeng River. In order to improve the water diversion efficiency of the Xinmeng River project, implementation suggestions for the gate-controlled scheme of branch river during the water diversion period, non water diversion period, and emergency drainage period were discussed and proposed, providing a certain reference for the operation and optimization scheduling of the Xinmeng River project.
