摘要
随着我国城镇化率的提高,现有城市在不断扩大,城市排水设施不能满足需求,大量地面硬化及河道被侵占,使得特大型城市排洪能力降低,下凹式立交桥在雨季形成积水重灾区。在大交通流状态下,积水影响道路通行能力,造成很大的问题。为解决这一难题,北京市修建了下凹式立交桥雨洪处理系统,充分利用地下空间彻底解决桥区积水问题。本文通过北京市十处桥区积水治理工程(莲花桥、六里桥、五路桥、大钟寺桥、木樨园桥、丰台大桥、丰益桥、左安门桥、菜户营桥、麻峪桥)的实践,总结开发利用地下空间的经验,为我国城市建设发展提供有益的借鉴。
As China's urbanization rate has increased,the expanding existing cities,urban drainage facilities can not meet the demand,a large number of surface hardening and the occupation of the river so large city drainage capacity reduction, and a sunken overpass hardest hit by water formed during the rainy season.Traffic flow in a large state,hydrocephalus affect road capacity,caused a big problem.To solve this problem,Beijing built a sunken overpass storm water treatment system,full use of underground space bridge area to solve water problems.In this paper,Beijing ten bridge district water treatment project(Lianhua Bridge,Liuliqiao Bridge,Wulu Bridge,Dazhongsi Bridge,Muxiyuan Bridge,Fengtai Bridge, Fenyi Bridge,Zuo'anmen Bridge,Caihuying Bridge,Mayu Bridge) practice,summed up the experience of development and utilization of underground space for China's urban construction and development to provide useful lessons.
