摘要
针对暴雨强度公式的超定非线性等特点,提出了将SCE-UA算法应用于不同重现期的暴雨强度与降雨历时关系式中参数的优化,并与优选回归法、遗传算法、粒子群算法和蚁群算法的优化结果进行了分析比较。实例应用结果表明,该算法可有效、快速地搜索到参数组全局最优解,且稳定可靠,提高了暴雨强度公式参数优化的精度,较其他算法具有一定的优越性。
According to the super-determined nonlinear characteristics of storm intensity formula, SCE-UA algorithm is applied to optimize the parameters of duration relationship between storm intensity and rainfall in different return periods. Compared with optimum regression method, genetic algorithm, particle swarm optimization and ant colony algorithm, the example results show that the proposed algorithm can search the global optimal solution of the parameter set effectively and quickly and it is reliable, which improves the parameters optimization accuracy of storm intensity formula and it has certain advantages over other algorithms.
