加速遗传算法在衬砌渠道横断面设计中的应用

Application of Acceleration Genetic Algorithm in Design of Lined Canal Transversal Section

一般的衬砌渠道横断面设计,需要进行反复试算和查图,计算量大,且精度不理想。可以将圆角梯形渠道渠底底宽计算问题转化为非线性问题后进行衬砌渠道横断面设计,并采用基于实数编码的加速遗传算法求解参数。结果表明这种方法计算精度高,能够满足工程设计需要,切实可行。

At present, try and error method and graphic method are routine methods despite their low efficiency. In this paper,a model based on non-linear mathematical model is established to determine lined canal transversal sections. Channel bottom width of are-bed trapezoidal canal can be obtained by real coding-based acceleration genetic algorithm. The results indicate that the method is more precise and practical than other traditional methods.
