1、水利水电技术第48卷2017年第1期基于两阶段人工鱼群算法的U型渠道断面优化设计柳智鹏1,朱成立1”,翟亚明1”,陈亮3(1.河海大学水利水电学院,江苏南京210098;2.河海大学南方地区高效灌排与农业水土环境教育部重点实验室,江苏南京210098;3.河海大学商学院,江苏南京210098)摘要:渠道断面优化是控制农田水利工程成本的重要因素,已有的渠道断面优化研究以梯形渠道为主,对U型渠道研究较少。以优化U型渠道深度、圆弧半径和直线段外倾角为目标,建立以U型渠道过水断面面积最小为目标函数、满足设计流量要求的数学优化模型。根据U型渠道水力计算的复杂性,利用引入协调行为的两阶段人工鱼
2、群算法,对渠道断面设计进行优化。优化结果满足边坡稳定等约束条件。将模型应用于连云港市赣榆区黑林镇土地整理项目,10条斗渠过水断面面积均减小,优化后占地面积共减少28.603m2,占原占地面积的5.0%。关键词:人工鱼群算法;协调行为;U型渠道;断面优化;两阶段doi:10.13928/j.cIlIci.wrahe.2017.01.028中图分类号:S277文献标识码:A文章编号:1000-0860(2017)叭一0149-05TwD-pha∞art嫩cial蜀蛐swaHnalgo—tllm-ba跎d叩缸aldesignofU-shapedch锄elsectionLIUZhipen9
