Abstract: In complex geological conditions and high-risk construction environments, the scientific establishment and efficient implementation of safety risk identification and collaborative control mechanisms in tunnel engineering serve as the core support for ensuring the safety, quality, and progress of expressway construction. The Luqiao Expressway traverses geologically complex structures, with variable surrounding rock conditions and adverse geological developments such as gas, posing severe challenges characterized by overlapping risks in tunnel construction. While basic safety management frameworks have been established in existing project management practices, significant gaps remain in the systematic identification of risks, dynamic assessment, multi-agent collaborative response, and the deep integration of technology and management. These shortcomings lead to prominent issues such as on-site measurement loss of control, frequent quality hazards, and delays in forecasting and early warnings. This study, grounded in the practical context of the Luqiao Expressway tunnel project, aims to thoroughly analyze the key causes and evolutionary characteristics of its construction safety risks. Furthermore, it seeks to explore and establish a holistic, multi-level collaborative control mechanism that integrates organizational, technical, informational, and institutional aspects throughout the entire process.
