Guo, Q; Amin, S; Wang, H and Yan, H (2024) Coupling simulation of human-environmental safety risk factors in metro construction: A case study of Rongjiazhai Station at xi’an Metro Line 5 in China. International Journal of Construction Education and Research, 20(1), pp. 26-42. ISSN 15578771
Abstract
The coupling of human, management, mechanical, and environmental risk factors increases the probability of accident occurrence at metro construction sites. The degree of coupling risks at metro construction sites is the degree of interdependence among the risks in subsystems during metro construction projects. This paper uses the coupling relationship between the human and environmental risks to predict the progression in overall risk-level of construction process at Rongjiazhai station of Xi’an Metro Line 5 in China. The coupling model and system dynamics simulation are applied in four steps: develop the coupling model, estimate the weight index for metro construction risk factors, calculate the risk levels, and estimate the degrees of coupling risks. This paper identifies that the change of coupling coefficients of human-environmental factors has a significant influence on the risk-level at metro construction sites. The "psychological and physiological quality", "natural and working environment", and "physiological discomfort and working environment" are the most influential factors of the coupling level of human-environmental risks. The simulation results demonstrate that the coupling effects of risk factors should be emphasized in engineering practice. To reduce the risk-level of construction system, the human, mechanical, and environmental risks should be identified, coupled, and monitored in real time.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
