摘　　要：根据拱坝的几何特征，应用寻优能力很强的遗传算法，结合拱坝应力分析的拱梁分载法，进行了三心圆等厚度双曲拱坝的优化设计。计算表明，该优化设计方法可行、合理。Based on the geometrical characteristics of arch dam＇s shape and GA with strong searching ability, an optimal design for a double-curvature arch dam with three circle centers and equal thick- ness by using the arch-cantilever method. Calculation results of a practical example show that the design method is feasible and rational.
