Abstract
Comprehensive and effective safety risk identification in metro construction has a significant impact on risk management. Although previous studies attempted to obtain a final ranking of the risk factors using various risk identification methods, they did not consider real-time risk identification. To address the complex issues involved, a model was established to identify the possible safety risks among the many potential risk factors in real time, considering the uncertain and complex environment in metro construction adjacent to buildings/structures. The study made decisions regarding the weights of the safety risk criteria at various stages of the construction. The safety risk factors and degrees of closeness were ranked at a specific time using real-time construction data. The model was demonstrated by real-time safety risk identification in a typical case study of metro construction adjacent to buildings/structures. The results are consistent with the reality of safety risks at various stages of such a metro project. The method of real-time risk identification is established to be feasible and effective, and experiments are proposed to identify risks in similar metro projects.

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
