摘　　要：针对目前核电厂在设计基准降雨条件下缺乏短历时雨型分析的现状,以某核电厂雨排水系统为研究对象,通过整理筛选国内外常用雨型表示方法,基于厂址可能最大降雨分析和水文特征条件,分析雨型对厂区水淹的影响。结果显示雨型有适用条件和精度的差异;雨峰强度直接决定了地面最大积水深度,雨型或潮位对地面水淹深度影响受局部区域管网排水能力制约,在审评中必要时可建立二维雨洪数值模型结合雨型对复杂区域进行精确水淹分析。In view of the lack of short duration rainfall pattern for design basis precipitation,taking the drainage pipe system of a typical nuclear plant site as research object,through the screening of used rainfall pattern,based on the analysis of PMP and other hydrological characteristics of the site,analysis the effect of inundation on pant.The results show that：in the use of rainfall pattern should attention to the difference of applicability and accuracy;the maximum water depth is subject to the peak intensity of rainfall;the surface water depth effect by rainfall patterns restricted by the drainage capacity of the local pipe network,if necessary,the establishment of 2 D numerical model combined with the rainfall pattern could improve the review accuracy of flooding analysis in complicated place of plant.
