摘要
降雨条件下公交港湾式停靠站区域易产生积水,不仅会损害停靠区域路面健康,而且严重影响乘客出行体验与道路通行效率.北方地区城市有其独特的自然地理气候特征,低影响开发措施的设置具有局限性.以分隔带类型的港湾停靠站路段为研究对象,分析了传统港湾停靠站路段雨水处理模式及其存在的问题,结合北方地区道路适用的低影响开发措施,提出了港湾停靠站路段低影响开发设施布局方案,并分析了雨水径流排放机制.通过暴雨洪水管理模型(Storm Water Management Model,SWMM)软件模拟研究路段海绵模式下雨水径流的调控效果,发现研究区域低影响开发设计对雨水径流具有明显的削减和延迟作用.
Abstract
The bus bay-style station areas are prone to water accumulation under rainfall conditions,which not only damages the pavement's integrity but also significantly impacts passengers' travel experience and road traffic efficiency.Cities in the northern region possess unique natural,geographical,and climatic characteristics,imposing limitations on the implementation of low-impact developments.This study focuses on the non-separated belt type of bus bay-style station segments and analyzes the conventional rainwater management practices and associated challenges.By incorporating appropriate low-impact development measures suitable for the road conditions in the northern region,a layout plan for low-impact development facilities in the bus bay-style station segments is proposed,accompanied by an analysis of rainwater runoff discharge mechanisms.Using the SWMM software,the regulatory effects of rainwater runoff under the sponge model in the study area are simulated,revealing that the low-impact development design significantly reduces and delays the flow of rainwater runoff in the research region.
