城市轨道交通系统安全韧性思考与实践

Thinking and Practice of Urban Rail Transit Safety Resilience

[目的]城市轨道交通作为城市的重要交通基础设施,对保障城市安全有序运行至关重要。为应对城市轨道交通系统所面临的安全挑战,需探讨提升城市轨道交通系统安全韧性的策略。[方法]介绍了“安全”的相关定义和“韧性”的相关表述,提出了城市轨道交通系统安全韧性概念的内涵。基于上海轨道交通的建设和运营实践,结合具体案例,围绕隧道结构安全性、设施设备可靠性和系统协同性三个方面提出了提升城市轨道交通系统安全韧性的策略。[结果及结论]提出以强化本质安全、系统安全为核心,通过夯实隧道结构安全基石、强化关键设施设备可靠性、增强系统间匹配与协同等关键性举措不断提升城市轨道交通系统的安全韧性。

[Objective]As an important transportation infrastructure,urban rail transit is crucial to ensure safe and orderly operation of the city.In order to cope with the safety challenge faced by urban rail transit system,it is necessary to discuss the strategy of improving the safety resilience of the system.[Method]The relevant safety definition and resilience expression are introduced,and the connotation of the concept of safety resilience in urban rail transit system is put forward.Based on the construction and operation practice of Shanghai rail transit as well as specific cases,the strategy of improving the safety resilience of urban rail transit system is proposed from three aspects,i.e.tunnel structure safety,facility reliability and system collaboration.[Result&Conclusion]It is proposed that strengthening the intrinsic and system safety is the core task,and consolidating the safety cornerstone of tunnel structure,intensifying the reliability of key facilities and equipment,and enhancing the matching and coordination between systems are the key measures to continuously improve the safety resilience of urban rail transit system.
