摘要：
The construction worker is both a receiver and an influencer to safety loss. However, rare researchers pay attention to the relationship between construction worker and construction safety risk. Therefore, this article proposed a new node mapping relationship model to explore the correlation degree between construction workers and construction safety risk factors (CSRFs). That was a new tool for preventing safety loss in railway tunnel construction. The model first identified CSRFs by WBS (Work Breakdown Structure-RBS (Risk Breakdown Structure) analysis, and determined construction workers by OBS (Organization Breakdown Structure)-WBS analysis. Then, taking the construction activities as a link, the 2-model OBS-WBS matrix and 2-mode WBS-RBS matrix were used for establishing the 2-mode OBS-RBS matrix. The corresponding node mapping relationship network was further established and visualized by taking the construction workers, CSRFs as nodes and the maping relationships between them as edges. Correspondence analysis displayed the node mapping relationship between construction worker and CSRFs. Taking the Shengdetang Tunnel as an example, this model was utilized to explore mapping relationship between construction worker and CSRFs. Expert interview was used to demonstrate the model rationality and practicality. The results indicate that some construction worker have a clear directional mapping relationship with CSRFs. The results can help construction workers improve safety awareness and help project managers propose directional suggestions for risk mitigation for different workers. © 2024, Central South University Press.
