Uncertain geological conditions and dynamic work settings make tunnel construction very accident-prone. Key safety issues and repeating trends are identified in this work using a mixed method approach, combining accident data analysis, literature review, and stakeholder surveys. Using Fault Tree Analysis (FTA) and risk matrices, risks were evaluated and prioritized. Static measures (e.g., tunnel lining reinforcement, PPE use) and dynamic measures (e.g., real-time monitoring, early warning systems) were then combined. The results show that a dual-layered safety strategy can efficiently handle both expected and changing hazards. Future tunnel construction projects are advised to follow this integrated approach to increase safety results, guarantee cost effectiveness, and make the project scalable.

摘要

Uncertain geological conditions and dynamic work settings make tunnel construction very accident-prone. Key safety issues and repeating trends are identified in this work using a mixed method approach, combining accident data analysis, literature review, and stakeholder surveys. Using Fault Tree Analysis (FTA) and risk matrices, risks were evaluated and prioritized. Static measures (e.g., tunnel lining reinforcement, PPE use) and dynamic measures (e.g., real-time monitoring, early warning systems) were then combined. The results show that a dual-layered safety strategy can efficiently handle both expected and changing hazards. Future tunnel construction projects are advised to follow this integrated approach to increase safety results, guarantee cost effectiveness, and make the project scalable.
