【摘要】 [目的]简化传统方法,得到直接推求综合暴雨强度公式的方法。[方法]采用粒子群算法优化各重现期统一的综合暴雨强度公式的参数,直接推求综合暴雨强度公式,并通过对芜湖市降雨历时资料建立的综合暴雨强度公式的计算结果与传统方法进行了比较。[结果]采用粒子群算法直接推求的综合暴雨强度公式比传统方法的计算结果精度更高,且推求过程更简便。[结论]说明采用粒子群算法直接推求综合暴雨强度公式是可行的。更多还原

【Abstract】 [Objective]The research aimed to simplify the traditional method to construct universal rainstorm intensity formula(TM-URIF). [Method]Universal rainstorm intensity formula based on particle swarm optimization (PSO-URIF) was drawn by using PSO to optimize parameters of URIF,after that,PSO-URIF and TM-URIF were compared to construct the UEIF for Wuhu City. [Result]PSO-URIF is better than TM-URIF. [Conclusion]PSO-URIF can be used to constrct universal rainstorm intensity formula directly.更多还原
