摘　　要：计算均质土坝渗流问题的常用方法有三段法和两段法 ,它们在求解过程中需要试算图解 ,计算精度不高且人工计算量大。为此 ,把该渗流问题等价于一非线性优化问题 ,可用作者研制的加速遗传算法 (AGA)进行求解。实例的计算结果说明 ,AGA计算简便 ,求解精度高 ,通用性强 。The three section method and two section method are usually applied to seepage computation of homogeneous earth dam.The two methods demand trial and error or graphic method during resolving the problem.The precisions of calculated results are not only low but also the operation needs large amount of manual computation.For this reason,in this paper,it is pointed out that the seepage computation problem is essentially a nonlinear optimal problem,which can be resolved with the acclerating genetic algorithm (AGA) developed by the authors.The results of the application examples show that the AGA is much more convenient in use high precision in result and wide range of validity. It is a new strong tool for widely applying the three section method to engineering project of practical earth dams.
