Investigating the risk factors affecting the safety of tunnel constructions

The global increase in construction activity has resulted in a significant rise in construction-related accidents. Tunnel construction projects are particularly complex, which increases the risks involved. Numerous studies have been conducted on the subject to reduce the risks and improve safety. These studies have explored safety standards and regulations, methods of safety assessment, and environmental factors that can affect safety. Proper identification and management of these risks are crucial to ensure the safety of labourers and the successful completion of the project. The purpose of this study is to provide a comprehensive review of the risk factors that can affect construction safety in tunnels. A better understanding of tunnel safety can be achieved through the identification and analysis of risk factors, leading to improved workplace safety management strategies in the tunnelling industry.
