摘要
随着城市化进程的加快,城市雨水径流问题日益严重,不仅对城市生态环境造成负面影响,还可能对城市排水系统造成巨大压力.本文以昆明理工大学呈贡校区憬园为例,采用SWMM模型对雨水径流进行模拟,并针对低影响发展(LID)技术进行改造研究.首先,通过对研究区域进行实地调查和资料收集,建立SWMM模型,然后对现有排水系统进行模拟,分析其存在的问题.其次,在其基础上引入LID技术对排水系统进行改造,通过增加雨水花园、植草沟、透水铺装等绿色设施,降低雨水径流对城市的影响.最后,通过模拟分析,验证了改造后的排水系统在减轻雨水径流、降低洪峰流量等方面取得了良好的效果,为校园雨水管理和雨水花园景观设计提供了理论支持和实践借鉴.
Abstract
With the acceleration of urbanization,the problem of urban stormwater runoff is becoming more and more serious,which not only has a negative impact on the urban ecological environment,but also may cause great pressures on urban drainage system.this study takes the Gallery Park of Chenggong Campus of Kunming University of Science and Technology as an example,adopts SWMM model to simulate stormwater runoff,and studies the transformation of low impact development(LID)technology.Firstly,the SWMM model is established through field investigation and data collection in the study area,and then the existing drainage system is simulated to analyze its existing problems.Then,LID technology is introduced to transform the drainage system and reduce the impact of stormwater runoff on the city by adding green facilities such as rainwater gardens,grass ditching and permeable paving.Finally,through the simulation analysis,it is verified that the improved drainage system has achieved good results in alleviating stormwater runoff and reducing flood peak discharge.This study provides theoretical support and practical reference for campus stormwater management and rainwater garden landscape design.
