Abstract With the rapid urbanization and development of China, urban utility tunnels (UUTs) that combine various city lifelines are developing quickly. However, along with the convenience brought by UUTs, these concentrated lifelines also create more potential hazards. To overcome the shortage of traditional hazard identifications and match the characteristics of UUTs, the EPE model (Energy transfer theory - Preliminary hazard analysis - Evolution tree) is proposed in this paper. Based on the EPE model, a series of well-organized hazard lists of UUTs are presented, including 189 hazards in 28 categories, covering common hazards, specific hazards and risks of multi-hazards of UUTs. Following the identification of worst-case accident scenarios, a comparison analysis of UUTs and traditional pipelines is performed. Moreover, several practical suggestions regarding long-term planning, durability, classification and regulation of UUTs are proposed. This research may be helpful to establish safer, more coordinated and efficient UUTs to facilitate city life.

我国城市综合管廊危害识别与分析

摘要 随着我国城市化进程的加快和发展，结合各种城市生命线的城市综合管廊（UUTs）发展迅速。然而，在UUT带来的便利的同时，这些集中的生命线也带来了更多的潜在危害。为了克服传统危险识别的不足，匹配UUTs的特点，本文提出了EPE模型（能量转移理论-初步危险分析-进化树）。基于EPE模型，给出了一系列组织严密的UUTs危害清单，包括28类189个危害，涵盖UUTs的常见危害、特定危害和多重危害风险。在识别出最坏的事故场景之后，将对 UUT 和传统管道进行比较分析。而且，提出了一些关于 UUT 的长期规划、耐用性、分类和监管的实用建议。这项研究可能有助于建立更安全、更协调和更高效的 UUT，以促进城市生活。
