The road surface,as a drainage channel,plays a crucial role in the drainage of water-logging.Based on SWMM,the hydraulic drainage model of road open channel flow coupled with pipeline pressure flow is developed.As the main road,Zhuzhou road in Jiaozhou city is selected to vevaluate the capacity of the road under the condition of unconventional-2%road cross slope in two situations.The results show that during extreme rainstorms,the road,functioning as a dual-purpose drainage and flooding control facility,combining emergency and normal use,has effectively achieved the design objective of enhancing drainage capacity.
