Abstract
To explore the influencing factors and mutual influence mechanism of the construction safety of China’s high-speed railway stations, this study takes the Hanghuang high-speed railway Fuyang station as the subject and studies 17 risk factors in 4 categories affecting construction safety based on system safety theory, and the interaction relationship and degree among the factors were analysed. Based on DEMATEL (Decision-making Trial and Evaluation Laboratory) and ISM (Interpretative Structural Modelling) methods, through a questionnaire survey, the logical relationship among the influencing factors is quantified. Then, the influencing degree, influenced degree, centrality, and causality of the influencing factors were calculated, and a multilevel hierarchical hybrid model is established to systematically analyse the influencing factors and the mechanism of high-speed railway station construction. The results show that the factors of construction safety risk are summarized as 3 main factors, 6 important factors, and 7 direct factors and personnel factors and management factors need to be controlled with emphasis. In addition, some measures are proposed. This research provides a theoretical basis and method for preventing accidents and improving the safety of high-speed railway station construction.
Highlights
With the rapid development of China’s high-speed railway, its construction scale and speed of development have ranked first in the world [1]
Construction accidents in high-speed railway station construction are the result of the joint actions of humans, machines, the environment, and management
Based on system safety theory, an index system of the influencing factors of construction safety is established with humanmachine-environment management aspects, and the influencing mechanism among the influencing factors is analysed. e main conclusions are as follows: (1) DEMATEL and ISM can be combined to analyse the relationship among various factors affecting construction safety
Summary
With the rapid development of China’s high-speed railway, its construction scale and speed of development have ranked first in the world [1]. E construction of a high-speed railway station has the characteristics of a typical complex social technology system: nonlinearity, emergence, feedback loops, and so forth [27]. Safety and actual accidents are emerging attributes of nonlinear interactions between different components of complex sociotechnical systems. We combine DEMATEL and ISM to establish the relationship among factors affecting the construction safety of high-speed railway stations and establish a multilevel hierarchical structural model. En, the importance of the influencing factors and their hierarchical relationship is determined, and the influence of these factors on high-speed railway station accidents is determined. Is study provides a theoretical basis and method for preventing accidents in the construction of high-speed railway stations Some countermeasures are proposed. is study provides a theoretical basis and method for preventing accidents in the construction of high-speed railway stations
