摘　　要：城市雨水利用是解决城市水资源问题的有效途径之一。本文针对传统集雨水窖对大面积集雨需要的局限性,设计了一种新型大容积集雨水窖,提出了由集雨量准确确定出其对称面内轮廓线形状的设计计算方法,并从经济效益、生态效益和社会效益对集雨水窖的建设进行了论证。结果表明:所提出的选形方法可用于实际工程问题的设计计算;效益评价说明大容积水窖的建设会产生一定的经济效益,而社会效益和生态效益将更加显著。该新型大容积水窖的研究,将为城市大面积雨水积蓄终端设施的设计提供一定的依据。Urban rainwater utilization is one of effective ways to solve the problem of urban water resources. As a solution to the limitation of traditional water cellar which can＇t satisfy the request of large-scale rainfall collection, this article put forward a new design of a large volume water cellar and a method which can determine its inner outline in symmetry plane according to rainfall collecting volume. It discussed the constructions of water cellar from economic, ecological and social benefit. The results show that the selection method can be used to design and calculate the practical engineering problems. The benefit evaluation shows that the construction of new large volume of water cellar can bring certain economic benefits. The ecological and social benefit will be more significant. The research on the new large volume water cellar will provide certain basis for the design of urban big area rain fall saving facilities.
