Resilience Assessment of Railway Transit Network in Coastal Cities in the Context of Climate Change—A Case Study of Shenzhen
In the context of global climate change,the rail transit network of coastal cities is at risk due to sea level rise and its associated effects.We employ Shenzhen as a case study for the modelling of complex networks and the assess-ment of the resilience of rail networks under various future scenarios.The findings indicate that the resilience of the rail net-work is significantly impacted by sea level rise,with this impact increasing further when the cumulative effect of climate change is considered.Furthermore,failures at key stations have a relatively greater impact on the rail network,as failures at key stations can lead to indirect failures at other stations.The coastal area of Shenzhen is characterised by several areas of severe surface subsidence,with the rail stations located within these areas being affected by both surface subsidence and sea level rise.In summary,we take sea level rise and its associated hazards as the context for the resilience assessment of the railway network,with surface subsidence taken into account.The study results provide a theoretical reference for the long-term safe development of rail transport in coastal cities.
