不同管网平面布置形式下低影响开发的雨洪控制效果研究
Study on stormwater control effects of low impact development measures under different drainage pipe network plane layout forms
摘要
Abstract
This paper presents the results of orthogonal and parallel stormwater drainage network layout types impact on stormwater control effects of 4 low impact development (LID) measures (permeable pavement,vegetative swale & rain garden,green roof,LID combination) in a high-density residential area of the Jiefangxi watershed,Jin' an District,Fuzhou City.Stormwater runoff and LID controls under different rainfall characteristics (return period,duration and peak position) were modeled by the PCSWMM 2015 developed by the Computational Hydraulics International.The findings are that when in small rainfall return period,long rainfall duration and early rain peak occurrence,the reduction effects on outlet peak flow of 4 LID measures under parallel type was better than orthogonal type.Under different rainfall characteristics,the reduction effects of permeable pavement,green roof and LID combination measure on outlet SS peak concentration under parallel type were better,and the reduction effects of vegetative swale & rain garden on outlet SS peak concentration under orthogonal form was better.The study can provide scientific evidence to screen the optional choices from two types of stormwater drainage network layout and the LID measures in the process of sponge city construction.关键词
