以某核电基地为例，对可能的暴雨积水状况进行模拟。核电基地厂区排水状况与一般城市地区相比，具有排水标准高、地表透水性差、地下管沟多且复杂、不设雨水泵站等明显特点，建模时也应该有合理的应对方法。利用 SWMM 模拟计算后可以得到管段内的水位随时间变化的过程线、节点积水状况等结果，进而得到积水节点附近的积水水深变化过程。计算结果表明：设计和校核不仅要注重暴雨重现期，而且要对排放水位设定合理的标准；该案例中上下游管道几乎同时出现洪峰，管道系统内没有调蓄容积；在用推理公式法时，地表汇水时间的取值对结果有较大影响。

It is necessary to simulate possible flooding process during heavy rain in a nuclear power plant.Taking a nuclear power plant as an example,the drainage condition of plant was com-pared with a municipal drainage system,which showed that it had some characters including stric-ter requirement,poorer surface permeability and no stormwater pumping station.As a result,modeling needed some reasonable methodologies to deal with these characters.Water level changing with time in conduit sections,flooding conditions in nodes and other consequences could be obtained by SWMM simula-tion calculation.Furthermore,the flooding depth changing process around the nodes could also be simula-ted as well.The analysis of calculation results showed that both heavy rains return period and discharge water level should be paid more attention to and a reasonable standard in design and checking should also be built up.The flooding peak in the upstream and downstream appeared almost simultaneously in this case,so there was no storage volume in the system.The surface runoff time values had great influence on the result if a reasoning formula method was used.
