Abstract

In order to clarify the mechanism of risk factors in underground caverns affecting the risk perception level of construction workers, the theory of psychological distance was applied to construct the SEM model and the vector model. Firstly, combined with literature review and field investigation, the factors influencing the risk perception of underground cavern workers were determined. Then risk perception factors were summarized into three distance dimensions by using psychological distance theory, the SEM of psychological distance was constructed and the path coefficients of the impact of psychological distance on risk perception level were calculated. Finally, the sensitivity coefficient of each psychological distance to risk perception level was calculated by using vector model, and the accuracy of SEM calculation was verified. The results show that the income distance dimension has the greatest impact on the level of worker's risk perception. © 2019 China Safety Science Journal
