In order to substitute experiential arithmetic which needs a lot of calculation and repeated work, this paper attempts to make use of immune genetic algorithm to optimize trapezoidal channel section, and applies this method to the channel upgrade of the second irrigation district for the Yanghe River in Hebei.
为了替代计算量大、重复工作多的传统经验试算法,通过尝试采用免疫遗传算法(IGA)对梯形渠道横断面设计进行优化,并将该方法应用于河北省怀来县洋河二灌区渠道改造工程。
