为了建设符合中国国情的地下排水深隧，解决城市内涝问题，消除“城市看海”现象，采用调研分析的研究方法，通过调研国外城市排水深隧建设的成功案例，借鉴成熟经验并结合我国国情探索出我国城市排水深隧在规划设计、施工技术等方面的建设模式。主要结论如下： 1)深隧规划必须坚持雨污分流原则，防涝标准应设为百年一遇； 2)深隧层位应建于地下30~50 m的位置，隧道管线应布设在城市易涝区，并且将修建深隧、改造浅管和清淤河道衔接起来，形成一套完整的防洪排涝系统，让深隧的作用得以充分发挥，才能解决城市内涝问题； 3)排水深隧要注重防水设计，防止雨水污染地下水； 4)为提高深隧的经济效益，应将深隧与地下快速路的规划结合起来，功能上多样化。

The waterlogging in some urban areas in China is serious, as a result, it is very important to build proper underground drainage tunnels in these areas. The successful cases of deep urban drainage tunnels in other countries are studied; meanwhile, the proper modes of planning, design and construction technology of deep urban drainage tunnel in China are discussed. Some main conclusions are as follows: 1) The principle of rainfall and sewage separation should be kept; and the flood control standard should be rather strict. 2) The drainage tunnels should be located underground 30-50 m in areas are prone to waterlogging. 3) A flood control and drainage system connecting tunnels, shallow pipelines and desilting riverway should be established. 4) The planning of deep drainage tunnels and underground expressway should be connected so as to improve the economical benefits of deep drainage tunnels.
