摘要
常规的渠道横断面设计,需进行反复试算,且精度不理想。以渠道设计水深作为优化变量,将均匀流公式计算设计流量转化为非线性优化问题的目标函数,设计流速界于不冲不淤流速之间作为约束条件,并用实数编码的遗传算法求解,进行渠道横断面设计,运用结果表明该方法计算精度高,简便可行。
In the conventional design of canal, the step is very simple, but it needs to repeat the process of try and error for many times, and the precision of results is always slow. This paper presents a method to determine the transverse sections of canal based on non-linear mathematics model, and use genetic algorithms to solve the model. It can be obtain canal parameters without erosion and sediment. The results of a example indicate that the method is practical and effective.
