摘　　要：南四湖二级坝枢纽是分泄南四湖上级湖洪水入下级湖的控制工程,为了解决闸门开启过程中可能出现的实际下泄流量与调度指令泄量误差较大的问题,论述了泄量纠偏模型知识库的构建内容,泄量纠偏模型构建和训练过程,以及应用流程和应用实践结果。该模型具有较强的数值模拟能力,可广泛应用于其他流域大型水闸工程,为水旱灾害防御提供决策支持。The secondary dam junction of the Nansi Lake is a control project to discharge flood water from the upper lake into the lower lake,In order to solve the problem that there may be a large error between the actual discharge flow and the dispatch instruction discharge in the process of gate opening,the construction content of the discharge correction model knowledge base,the construction and training process of the discharge correction model,the application flow and the practical results are discussed.The model has strong numerical simulation ability,and can be widely used in large-scale sluice projects in other river basins to provide decision support for flood and drought disaster prevention.
