Abstract

Abstract:

In order to improve the stability and accuracy of the assessment of unsafe behavior of high-altitude railway construction personnel, a psychological measurement scale of unsafe behavior of high-altitude railway construction personnel was compiled from five aspects: safety physiology, safety psychology, safety management, safety environment and safety ability. It was measured for the construction personnel of the Ganqing Tunnel Project of Xicheng Railway. The rough set theory was used to reduce attributes, data mining and calculate the importance of the results. The evaluation system of unsafe behavior level of construction personnel was constructed, and the software Matlab forward cloud generator was used to draw a comprehensive evaluation cloud map of unsafe behavior level to visually express the evaluation results. The results show that the unsafe behavior assessment results obtained by the evaluation system are consistent with the actual situation on site, and the evaluation system can monitor the unsafe behavior of construction personnel at high-altitude areas in real time, which is beneficial to improving the safety behavior level of construction personnel.

Key words: high-altitude railway project, construction personnel, unsafe behavior, rough set theory, cloud model, entropy weight method(EWM)
