摘　　要：大坝安全的组合优化监控模型实际上为一带约束的优化问题,将DNA遗传算法应用于大坝安全监控领域中,用罚函数法将有约束的优化问题转换为无约束的优化问题,建立了大坝安全监控的组合优化模型。实例计算表明,该方法是可行的,所建立的组合优化模型在拟合与预报精度上要优于单一的模型。The establishment of a combined optimal monitoring model for dam safety is actually an optimization problem with constraints. Based on DNA genetic algorithms, a combined optimal monitoring model for dam safety is established. By use of penalty functions, an optimization problem with constraints is converted to non-constralnt one to estahlish the combined optimal monitoring model for dam safety. The calculation of an example indicates that the combined optimal model is better than the single one in terms of simulation and prediction precisions.
