Cross-system modeling and analysis of cascading failure propagation in large-scale metro stations under extreme flooding events

Key Points

• Cascading failure propagation was identified as a critical concern during extreme flooding events.
• Key evidence revealed that specific systems may experience failure under severe conditions, leading to broader infrastructure issues.
• Modeling techniques were employed to simulate and analyze the resilience of large-scale metro systems during flooding scenarios.
• This analysis highlights the necessity for improved design strategies to mitigate cascading failures during extreme weather events.
