摘　　要：简要介绍了基本遗传算法的原理,并对遗传算子作了改进.将改进后的遗传算法应用于大型预应力U型渡槽优化设计中,计算结果验证了优化设计方案的可行性与有效性.The principle of the simple genetic algorithm is briefly introduced and one of the genetic operators is improved in this paper. Finally, the improved genetic algorithm is used in the optimal design of a large-scale pre-stressed concrete U-shaped aqueduct. Calculation results show that the improved method is feasible and effective.
