Abstract

In order to explore the mechanism of safety risk factors in subway tunnel construction and prevent construction safety accidents scientifically, the N⁃K model was introduced into the evolution coupling analysis of safety risk in subway tunnel construction. On the basis of the definition of construction safety risk factors and the analysis of the coupling mechanism, the coupling interaction scenarios were constructed according to the coupling hierarchical network model, and the combined classification was carried out according to the number of coupling. The coupling effect measurement model based on N⁃K model was established, and the coupling information multivariate interaction and coupling effect quantitative calculation were carried out. The validity and accuracy of the model were verified by taking 231 typical accidents of subway tunnel construction in China in recent 20 years as examples. The results show that safety accidents are directly proportional to the risk coupling value, and the more coupling factors, the greater the risk value. The coupling risk value of human and management is the highest, and the coupling risk value of management and environment is the lowest. The coupling of subjective and objective factors is more likely to lead to safety accidents. © PHYSOR 2022 China Safety Science Journal. All rights reserved.
