摘　　要：根据微灌毛管水力学特性,应用遗传算法理论和方法,提出微灌毛管水力解析及设计的新方法,建立了两种典型毛管水力解析和设计的遗传算法模型及求解方法,该方法可适用于非均匀坡度、不等间距及不等流量灌水器的毛管解析和设计。模拟计算结果表明,该方法具有较高的求解效率和计算精度。Based on the characteristics of micro-irrigation laterals and the theory of genetic algorithms, a new method and two genetic algorithms typical models for micro-irrigation laterals analysis and design were put forward. The problems of laterals vary in slope and emitters spacing and flow could be analyzed and designed by using this model and method. The results of simulated calculation indicated that the model and method have the high solving efficiency and precision.
