针对常规渠道断面优化设计中存在的试算工作量大、累积误差大、计算精度不高的问题,将鲁棒性强、收敛速度快且全局寻优性能优异的人工蜂群算法引入渠道断面优化设计中,通过建立包含水力要素与经济要素的多目标优化函数,采用人工蜂群算法在全局空间下搜索渠道断面优化问题的全局最优解。研究结果表明,该方法是可行的,具有高效快速、计算精度高和易于实现等优点。
With regard to the problems of huge tentative calculation, high accumulative error and low precision in the conventional optimal design for channel section,the artificial bee colony algorithm with good robust,high convergence speed and outstanding performance on solving global optimization problems was applied to the optimal design of channel section.Through establishing the multi-objective optimization function considering the hydraulic conditions and economic factors,the global optimal solutions to the problems of channel section were searched by means of the new method based on the artificial bee colony algorithm.The results show that the proposed method is feasible and has the advantages of high efficiency,high precision and being easy to implement.
