中文摘要：

城市深隧排水系统是一种能够有效缓解城市内涝问题、解决雨洪和溢流污染的重要措施.该系统在国外多个国家已经有了较为成熟的应用,取得了一些值得借鉴的经验.近几年国内许多城市暴雨内涝事件频发,也使得对城市深隧排水系统的研究更为重要.通过对城市深隧排水系统原理以及国内外典型工程应用案例的介绍和总结,可为我国今后在深隧排水系统建设及运行中更好地发挥其减污、防涝综合作用提供技术支撑.目前深隧工程在模拟评价、调度管理以及与其他工程的联合设计等关键技术问题上已取得了一些成果,但仍面临着管网衔接、施工地质、地下大容量泵站建设、运行管理等一系列技术问题,这是城市深隧排水系统未来发展的关键所在,同时也为今后的研究指明了方向和目标.总的看来,城市深隧排水系统研究在我国具有迫切的现实需求和广阔的应用前景,需要结合我国各城市特点进行系统规划和建设.

英文摘要：

Urban rainstorm-waterlogging events were becoming more common and more difficult to control in the past decade. With the inadequate capacity of urban drainage system and the low standards of drainage planning, it is urgent to reform and improve the original drainage system. However, due to the constraints of space conditions, construction costs, environment interference and some other factors, it is not easy to transform the original drainage system and the effect is not obvious. Urban deep tunnel drainage system is an important method to alleviate urban waterlogging, as well as the initial runoff pollution and overflow pollution. The research on urban deep tunnel drainage system is necessary and important, especially in rapid urbanizing countries like China. The preliminary planning and studies have been done in several cities in China with the aim of solving urban waterlogging problem by urban deep tunnel drainage system. This kind of system has already been applied maturely in many developed countries/cities, such as Singapore, Chicago, London and so on. These applications can provide many experiences and lessons for Chinese engineers and researchers. By introducing the work principle of urban deep tunnel drainage system and analyzing its design and uses at home and abroad, this review provides technical support of deep tunnel system to reduce pollution and waterlogging. From the typical cases investigated in this paper, they confirmed that the urban deep tunnel drainage system could play a multiple role in urban waterlogging control and reducing overflow pollution. For example, in London, Paris, Singapore, they are used for drainage and the pollution control of overflow; in Tokyo and Hongkong, they are used for urban waterlogging control; in Chicago they are used both for waterlogging control and overflow pollution control. Although the experience of foreign countries and cities can be used for a reference to the system＇s development in China, it cannot be completely copied. Besides, this review paper also
