摘要
以实际工程为例,结合海绵城市及低影响开发的政策要求和计算理论,通过亳州市魏武大道高架桥排水设计,介绍了在高架桥下设置生物滞留带和中心渗沟作为桥面雨水主要海绵措施的计算方法,经对比分析,阐述了高架桥雨水直接用于绿化浇灌的优点和前提,旨在为类似工程的设计提供参考。
Taking the drainage design of Weiwu Avenue Viaduct in Bozhou City as an example,combined with the policy requirement and calculation theory of sponge city and low-impact development,this paper introduces the calculation method of the biological retention belt and central sewer set up under the viaduct as the main sponge measures of deck rainwater.After the comparison and analysis,this paper sets forth the advantages and premise of viaduct rainwater directly used for the greening irrigation,which is aimed at the reference for the design of the similar projects.
