基于遗传算法的九乡河双扉闸门优化设计方法及应用

Study and application on the optimization design of double–leaf gate of Jiuxiang River based on genetic algorithm

防洪排涝一直是城市河道整治所关注的重要问题。建设具有挡洪、行洪、蓄水和反向引水功能的双扉门闸站是十分必要的,其中对闸门的尺寸进行设计优化,具有重要的研究意义。采用具有快速全局搜索功能的遗传算法,对闸门尺寸进行优化搜索,通过分析计算闸门启闭力的合理性,确定搜索结果的优略。结果表明,采用遗传算法进行优化搜索过程简单快捷,搜索时间仅为23.85 s,搜索结果也能够为设计提供科学的参考依据。

Flood control and drainage has always been an important issue in urban river regulation.It is very necessary to construct a double-leaf gate station with functions of flood control,flood discharge,water storage and reverse water diversion,and it is of great research significance to optimize the size of the gate.The genetic algorithm with fast global search function was used to optimize the search of the gate size.The rationality of the gate opening and closing force was calculated and analyzed to determine the superiority of the search results.The results showed that the search process was simple and fast,the search time was only23.85s,and the search results could provide scientific reference for design.
