城市地下综合管廊常见运维灾害及对策研究

城市地下综合管廊作为现代化城市建设中不可或缺的一种重要基础设施,是保持城市能量流、物质流及信息流畅通的众多生命线之家,然而可以预见大量的灾害将成为其正常运行的严重威胁。在对国内外城市地下综合管廊灾害事故统计分析的基础上,结合与之具有一定程度相似性的市政管线(或隧道)及其他类型运营隧道灾害,系统划分了其运维期灾害类型,并对自然灾害、技术灾害和人为灾害类型进行了细分,提出了其运维期灾害防控的基本原则。在此基础上,重点分析总结了综合管廊火灾和震害的产生机理和应对措施;还就人为灾害、渗漏水问题、不均匀沉降以及环境安全问题及其对策进行了研究。研究成果可为运维期综合管廊减灾防灾提供参考。

The Common Operational Disasters and Countermeasures of Utility Tunnel in Urban

As an indispensable infrastructure during modern city development, utility tunnel is the home of many lifelines which keeps city energy flow, material flow and information flow unimpeded. However, it can be predicted that a large number of disasters will become a serious threat to the normal operation of utility tunnel. Based on the statistical analysis of utility tunnel disaster accidents, and referred to operational disasters of municipal pipelines (or tunnels) and other types of tunnel, we systematically classified the types of operation disasters of utility tunnel, it also split natural disaster, technological disaster and man-made disaster into small hazards, besides, basic principles of disaster prevention during operation period of utility tunnel were raised. Based on the work above, the mechanism and countermeasures of fire and quake-proof of utility tunnel were summarized. Meanwhile, many other hazards such as man-made disaster, leakage problems, differential settlement and environmental safety problems were also studied. The results can be used as a reference for disaster prevention and mitigation in operation period of utility tunnel.
