Transient aerodynamic loads and spatiotemporal evolution of the temperature field in cold-region high-speed railway tunnels

Key Points

• Aerodynamic loads significantly influence the temperature field in high-speed railway tunnels.
• The analysis demonstrates a complex interaction between transient loads and temperature variations over time.
• Observational analysis captured the temperature field dynamics influenced by the tunnel's aerodynamic characteristics.
• The findings suggest that better understanding of airflow can enhance tunnel design and safety measures.
