针对传统经验试算法的低效性,将遗传算法(GA)用于解决田间排水工程设计中的非线性优化问题。从田间排水系统的任务出发,分别介绍了田间排水沟的断面优化设计和间距优化设计方法,并运用遗传算法进行模型求解。实例表明,遗传算法能够有效解决田间排水沟的优化设计问题,并且能严格满足系统约束条件,操作简单,计算效率高。

Aiming at inefficient of the traditional method of trial experience, this paper solved the non-linear optimization problem of field drainage engineering by using genetic algorithm （GA）. According to the task of the drainage system, this paper introduced the optimization design method for sections and space of the drainage field, and used genetic algorithms to solve model. The examples showed that the genetic algorithm not only could effectively solve the problem of optimal design of the drainage field and meet the restrictive conditions, but also was simple and efficient.
