城市深层排水隧道规划建设全过程重难点探析

Analysis on Difficulties During Planning and Construction Process of Urban Deep Drainage Tunnel

深层排水隧道凭借其具有线性收集、类型多样、调蓄扩展、污染物可控、环境影响小等特性日益受到关注,并已越来越多地应用在经济较好且仅依靠浅层排水系统以及海绵城市措施难以解决问题的城市中。通过分析国内外深层排水隧道系统的功能、系统布置、组成部分等内容及解读部分学者的相关文献,探析了深层排水隧道在规划、设计、施工、运维4个阶段的重难点问题,并进行了分类总结,以期为深层排水隧道工程的研究、建设与管理提供参考及借鉴。

Deep drainage tunnels are attracting more and more attention due to their characteristics of linear collection, diverse types, storage expansion, controllable pollutants, and low environmental impact. And more and more applied in some special cities, whose economic are usually better and problems can’t be solved only rely on shallow drainage systems and sponge city measures. By analyzing the contents of functions, layout, components, etc of deep drainage tunnel systems at home and abroad, and interpreting the relevant literature of some scholars, the important and difficult problems in the four stages of planning, design, construction, and operation and maintenance are explored and classified. It is hoped to provide reference for the research, construction and management of deep drainage tunnel engineering.
