低影响开发(LID)下的城市互通立交排水设计

Drainage Design of Urban Interchange under Low Impact Development

随着我国城镇化的快速发展,互通立交已经成为了城市发展的重要标志,而城市基础设施、城市管理能力等因素跟不上城镇快速发展的需要,各种城市病累积爆发,尤其是近年来频发的“城市内涝”现象,对城市居民生活质量造成了严重影响,制约了城市的快速可持续发展。为了贯彻我国“海绵城市”建设理念,以西安市酒十路互通立交为依托,探讨低影响开发下的立交排水设计,并结合实际案例提供一些建设性的经验。

With the rapid development of urbanization in China,interchanges have become an important symbol of urban development,and that the urban infrastructure,urban management ability and the other factors cannot keep up with the needs of the urban rapid development.All kinds of city disease cumulatively break out,especially in recent years,the frequent occurrence of the"urban waterlogging",which seriously affect the life quality of urban residents,and restrict the rapid and sustainable development of the city.In order to implement the construction idea of"sponge city"in China,relying on Jiushi Road Interchange in Xian,the drainage design of interchanges under the low impact development(LID)is discussed,and some constructive experience is provided with the actual cases.
