Commonly used methods to calculate seepage problems of homogeneous earth dam are three-section method and two-section method. They require trial calculation in the process of solving, the calculation accuracy is not high and the man-made calculation is large. To this end, the seepage problem is equivalent to a nonlinear optimization problem, which can be solved by an accelerated genetic algorithm (AGA) developed by the author. The calculation results of the examples show that the AGA calculation is simple, the solution accuracy is high and the versatility is strong. It provides a new powerful tool for the wide application of the three-stage method in the actual earth dam engineering design
