Overview

Case study demonstrates a new framework identifying key fire risk drivers in cable tunnels, supporting effective management strategies.

Key Points

  • This study aims to develop a framework for assessing fire risk drivers in cable tunnels. It focuses on identifying factors that significantly influence fire risk variations.
  • Developed a contribution-oriented fire risk assessment framework for cable tunnels.
  • Established a hierarchical indicator system based on fire accident mechanisms and expert input.
  • Conducted scenario-based analyses to evaluate fire prevention strategies.
  • Identified that structural integrity factors, particularly fire door integrity and joint defects, are dominant fire risk drivers.
  • Showed pronounced spatial variability in fire risk across different tunnel segments.
  • Highlighted that risk management interventions vary in effectiveness depending on the identified key risk drivers.
