Abstract

Integrated underground utility tunnels are increasingly crucial in modern cities, addressing the pressing need for sustainable urban development. However, their extensive centralization amplifies both the complexity and scale of potential risks. When a utility tunnel accident occurs, it is possible to trigger a sequence of cascading events, thereby resulting a complex coupling accident. While previous research has predominantly focused on individual hazards, understanding multi-hazard coupling accidents presents significant challenges and lacks effective methodologies. In this paper, we propose an integrated system utilizing ontology technology and knowledge base construction for simulating and deducing coupling accidents in urban utility tunnels. Specifically, by extending ontology techniques to emergency decision-making and adopting the triangular framework for public safety, we establish a multidimensional information ontology for utility tunnel emergencies. Furthermore, a knowledge base for typical coupling accident evolution paths is established based on the event chain and contingency plan chain theory. Through integration with a multi-hazard accident basic database that serves the conditional, investigative and decision-making node within the evolution path, the simulation and deduction system is formulated, boasting a user-friendly visual interface, interactive functionality, and seamless applicability for widespread adoption. A case study demonstrates the system ability to support multiple paths and unified mapping deduction, offering practical emergency decision-making suggestions to mitigate cascading events in urban utility tunnels.
基于本体的地下管线隧道多灾害耦合事故模拟与推演系统--地震诱发灾害链案例研究
综合地下公用设施隧道在现代城市中越来越重要,满足了城市可持续发展的迫切需要。然而,其广泛的集中性扩大了潜在风险的复杂性和规模。当公用事业隧道事故发生时,有可能引发一系列连锁事件,从而导致复杂的耦合事故。以往的研究主要集中在单个危害上,而对多危害耦合事故的理解则面临巨大挑战,并且缺乏有效的方法。在本文中,我们提出了一个利用本体技术和知识库构建的集成系统,用于模拟和推断城市公用事业隧道中的耦合事故。具体而言,通过将本体技术扩展到应急决策领域,并采用公共安全三角框架,我们建立了一个针对公用事业隧道突发事件的多维信息本体。此外,基于事件链和应急预案链理论,建立了典型耦合事故演化路径知识库。通过与多灾害事故基础数据库的整合,形成了模拟推演系统,该系统具有友好的可视化界面、交互功能和无缝适用性,可广泛采用。通过案例研究,展示了该系统支持多路径和统一映射推导的能力,为缓解城市公用设施隧道中的级联事件提供了实用的应急决策建议。

期刊介绍: Elsevier publishes Reliability Engineering & System Safety in association with the European Safety and Reliability Association and the Safety Engineering and Risk Analysis Division. The international journal is devoted to developing and applying methods to enhance the safety and reliability of complex technological systems, like nuclear power plants, chemical plants, hazardous waste facilities, space systems, offshore and maritime systems, transportation systems, constructed infrastructure, and manufacturing plants. The journal normally publishes only articles that involve the analysis of substantive problems related to the reliability of complex systems or present techniques and/or theoretical results that have a discernable relationship to the solution of such problems. An important aim is to balance academic material and practical applications.
