摘　　要：分析了重力坝断面优化设计时设计变量的选取、目标函数的确定及约束条件的设置。针对遗传算法(GA)和模拟退火算法(SA)的特点,将2种算法结合起来,用于重力坝断面的优化设计。探讨了GA-SA混合算法的优化步骤及其MATLAB的实现。The selection of design variables, the determination of objective function and the setting of con-straint conditions of gravity dam section optimal design are analyzed. The genetic algorithm （LA） and sim-ulated annealing algorithm （SA） are combined with to optimize the gravity dam section according to theircharacteristics. And the optimization steps of the GA-SA hybrid algorithm are discussed, as well as the MATLAB implementation.
