已建城市排水管网的排涝能力评估方法
Evaluation of Drainage Capability of Urban Pipelines
摘要
Abstract
Based on measured precipitation and runoff data of the residential district in Guangzhou, China, this paper simulated the drainage capability of pipe network under different return period in resident district using calibrated SWMM. The results suggest that when faced with two years’ return period rainstorm, water would accumulated at Nodes J14, J15 and J31, and water accumulation would become more serious with increasing return period. When faced with five years’ return period rainstorm, accumulated water amounts at Nodes J15 and J31 were 1674m³ and 546m³, respectively, and accumulated water times were 0.5h and 0.4h, respectively. In view of low pipe drainage capability in our country, this paper suggested using LID measures to reduce peak flow of storm flood, so as to improve the existing drainage capability of the network. This paper built an assessment method of drainage capability for the existing urban pipe network, which not only could identify the main water spots and pipe flow section, but also could provide a dynamic, qualitative and quantitative evaluation of the ability of the drainage pipe network.关键词
