Research on Identification and Analysis of Hazards in High Altitude Tunnel Construction Operations

Tunnel construction is an important safety control scenario in transportation engineering construction. Due to its own characteristics, such as high weight of terrain and landforms, complex geological conditions, numerous environmental factors, and difficult management, tunnel construction safety management has attracted much attention. In different tunnel constructions, the difficulty of managing high-altitude tunnel construction is particularly prominent. This article focuses on the high-altitude areas represented by the Qinghai Tibet Plateau. Taking the Laze Tunnel as the research objective, a combination of on-site investigation, interview, and screening methods were used to identify the hazards of high-altitude tunnels from four aspects: personnel, equipment, environment, and management. Analyzed its existing problems and provided countermeasures and suggestions. This study lays a theoretical foundation and practical significance for the safety management of high-altitude tunnel construction operations.
