摘　　要：随着城市建设规模的不断扩大,大量土地用地性质发生了改变,硬地铺装和建筑物等不透水用地面积不断增加,改变了流域下垫面条件,使得降雨入渗、截留等大为减少,致使降雨产流时间缩短、泄流速度快、径流量和洪峰流量大为增加。此外,由于近年来极端天气频发,从而导致城区内涝频发。深隧工程是解决大城市内涝的主要途径,本文介绍了国内外几个典型深隧工程,分析了这些工程建设的背景、功能以及结构特征,并讨论了其面临的一些技术问题,如深基坑技术、隧道选型、结构形式、施工技术等。As the scale of urban construction grows,plenty of land use has been changed.The increasing of impervious area caused by hard pavement and buildings changed the underground conditions,leaving much less water infiltration and interception,which shortened the rainfall flow time and fastened the spreading speed,and therefore,the runoff and peak discharge grew rapidly.Besides,the frequent extreme weather also caused a good many waterlogging disasters in urban areas.Deep tunnel is a main solution to waterlogging problems in large cities.Several typical deep tunnels in the world are introduced in this paper,and the projects backgrounds,functions and structure properties are analyzed as well.Then some technical problems for constructing a deep tunnel are discussed,such as deep foundation technology,tunnel type selection,structure types,and construction techniques.
