城市市政排水与区域排涝水动力耦合模型研究
A coupled hydraulic model for urban drainage and regional waterlogging release
摘要
Abstract
Some cities, especially the costal cities, are prone to waterlogging when the storm occurs. The analysis shows that the geographical location of the city and the flood characteristics of the surrounding rivers are not comprehensively considered with the urban waterloging release, so the backward design method of urban drainage is one of the main causes of the waterlogging. To solve the problem, Saint Venant equations are used to express the key components of various water release system such as the open channel, rain pipe and field confluence, and through the connection relation among these components, a coupled hydraulic model for the urban drainage and regional waterlogging release is established. The practical application shows that the model can reflect the influence of river backwater and long-term storm on the urban drainage, which can be widely used in the urban drain-age planning and design work.关键词
