摘　　要：通过建立缓冲式排水模式管道、河网耦合水力模型,在运用推理公式法初步确定管道系统设计参数的基础上,通过模型试验对缓冲式排水模式管道系统的设计、应用条件进行了分析探讨,确保了缓冲式排水模式合理性和安全性.并以上海某地区为例,在2种典型工况下对缓冲式排水模式的应用条件进行了计算,同时以洪灾频率为指标对缓冲式排水系统的安全性进行了评价.这为不同河网条件圩区的缓冲式排水模式的设计和安全评价提供了新的方法.A coupling hydraulic model of conduits and channels was developed. On the basis of model simulation, the design and application conditions of conduits in the buffering stormwater drainage system, which were designed in a rational method, were analyzed and discussed to ensure the rationality and safety. Moreover, a case study was presented to illustrate the way of analysis and design of buffering stormwater drainage system, and the safety of buffering drainage system was assessed with the indicator of flooding frequency. It has provided a new way for the design and safety assessment of buffering storm water drainage systems in polders with various characters.
