摘　　要：结合无锡某厂区的防洪和雨水利用,根据厂区的地形、建设方案和市政规划,分析内涝的产生与山体洪水的威胁,计算排洪沟的尺寸,进行防洪和山体雨水利用设计,年可收集山体雨水量约4 711 m^3。通过年均水量平衡计算,厂区屋面年雨水收集量17 812 m^3,除满足景观及绿化用水外,有10 245 m^3可用于生产用水,使厂区径流系数减少52%。逐月计算水景、绿化、雨水收集及雨水处理系统的水量平衡,年可以收集利用22 523 m^3雨水,节约水费10万余元。Combined with the flood protection and rainwater utilization in a factory of Wuxi, and based on the topography, construction scheme and municipal planning of the factory, the cause of waterlogging and the threat of mountain flood are analyzed. The size of the drainage channel is calculated. The flood protection and the mountain flood rainwater utilization are designed. The annual collectable mountain rainwater flow is about 4 711 m^3. Through the annual average water balance calculation, the annual rainwater collection quantity from the roof of factory is 17 812 m^3. The water flow of 10 245 m^3 can be used for production besides meeting the water of landscape and greening, which makes the runoff coefficient of factor decreased by 52%.The water balance of water landscape, greening rainwater collection and rainwater treatment system is calculated month by month. The collectable and utilized rainwater quantity is 22 523 m^3, and the water fee can be saved more than 100 000 yuan every year.
