摘　　要：本文应用商用雨排水分析计算软件PCSWMM,建立双排水系统分析模型,模拟了某核设施厂址在极端降雨工况下的地下排水和地表径流过程。模拟结果显示,该核设施厂址在500年一遇降雨下的地表最大积水深度为0.13 m,与推理公式法计算结果0.10 m较吻合,较真实地反映出了实际防水淹能力,采用PCSWMM的双排水系统计算方法能较好地模拟最大积水深度结果。The research applies PCSWMM,a commercial rainwater analysis calculation software in the assessment of flood defending ability of a nuclear facility site. The double drainage systems analysis model was built up to simulate the process of under ground drainage and surface runoff in extreme rainfall in a nuclear facility site. The simulating result displays,the surface maximum water depth of the nuclear facility site 500 years at once is 0.13 meters. The calculating result is identical with the calculating result 0.10 meters of inference formula method. It can reflect the actual flood defense ability. The double-drainage-systems calculation method in PCSWMM could simulate the maximum flooding water depth result very well.
