城市轨道交通建设项目韧性评估、模拟及提升研究

Along with huge population surging into the metropolises of the country, urbanization has made a big progress in China over recent years. As one of the unwanted byproducts of rapid urbanization, traffic jam occurs widely and brings a lot of troubles to those who live in metropolises. To address the issue, most of the metropolises in China are promoting the construction of urban rail transit projects actively. However, the construction of such kind of project is always affected by many disruptive events such as extreme weather, unexpected geological disaster, and construction accidents. In order to minimize the impacts of these disruptive events, building and increasing resilience has been adopted as an important strategy. This proposed research aims to investigate the resilience of urban rail transit construction projects comprehensively. First, different kinds of disruptive events that may affect urban rail transit construction projects will be identified and their impacts will be assessed. Then, a comprehensive framework of resilience of urban rail transit construction projects will be proposed, and a model that can assess the resilience is to be created as well. After that, simulations of resilience targeting different disruptive events will be carried out. Lastly, an ontology-based semantic network system will be established with the intention of helping the authorities making right decisions. This proposed research can help increase the capabilities of urban rail transit construction projects in dealing with disruptive events, and from there ensure the success of project implementation.

近年来，伴随着我国城市化进程的稳步推进，大量人口持续涌入各大国家中心城市及各省会中心城市。为有效缓解因大量人口集中而导致的交通出行拥堵问题，各大中心城市都在积极推进城市轨道交通项目建设。然而，城市轨道交通建设项目往往会受到极端天气、地质灾害、施工安全事故等各类干扰性事件的影响。为将此类影响最小化，理论界和实践界正逐步采用“构造并提升项目韧性”这一策略。本课题聚焦于城市轨道交通项目建设阶段的韧性问题：首先，系统性地梳理城市轨道交通项目建设阶段可能出现的干扰性事件并对其干扰性做出科学评估；其次，构建面向干扰性事件的城市轨道交通建设项目韧性理论分析框架及评估模型；随后，开展面向不同类型干扰性事件的项目韧性模拟仿真研究；最后，开发基于本体的项目韧性语义检索系统，为决策部门提供决策支持。研究成果将有利于提升我国城市轨道交通建设项目应对各类干扰性事件的能力和水平，确保项目的顺利实施。
