摘要
针对城市因不透水铺装面积过大引起的排水能力不足、城市内涝等问题,根据海绵城市具体建设要求,依托低影响开发理论,对城市道路进行优化设计,以探索适用的低影响开发设计方案。以浙江绍兴某试点区为例,从道路雨水系统、道路排水与雨水衔接系统及道路路面排水系统3个方面,研究了低影响开发优化设计理论,并在此基础上对道路横断面、纵断面以及路基、路面进行了优化设计。探索出的低影响开发设计方案,可为类似区域海绵城市建设提供参考。
Aiming at the problems of insufficient drainage capacity and urban waterlogging caused by too large impervious pavement are of city,based on the detailed construction requirements of sponge city and relying on the low-impact development theory,the design of urban roads are optimized in order to probe the applicable low-impact development design scheme.Taking a pilot zone of Shaoxing in Zhejiang as an example,the low impact development optimization design theory is studied from three aspects of road rainwater system,road drainage and rainwater connection system,and road pavement drainage system.And on this basis,the design of cross section,vertical section,roadbed and pavement of road is optimized in order to explore a low-impact development design scheme,which can be referred for the construction of sponge city in the similar regions.
