建立了一种基于渠道超高可变与漫顶洪水频率分析的梯形断面明渠渠道优化设计模型,模型根据漫顶洪水频率值计算确定渠道超高值,并采用传统优化算法与非支配排序遗传算法(NSGA Ⅱ)同时进行计算求解,通过模型计算结果与以往模型的对比,显示了本文模型的优越性与适用性。
A model of open channel optimization design for trapezoidal section open channel based on the analysis of channel hyper-variable and flood-top frequency was established. The model was based on the calculation of flood peak frequency to determine the channel super-high value. The traditional optimization algorithm and non-dominated ranking genetic algorithm (NSGA Ⅱ) is calculated and solved simultaneously. The comparison between the model calculation results and the previous model shows the superiority and applicability of this model.
