“…Material-type safety risks refer to the safety risks that arise from raw materials, components, semi-finished products, and finished products during construction (e.g., broken pipe segments, unqualified grouting materials); Method-type safety risks mainly focus on the construction technology aspects (e.g., shield tunneling technology and grouting technology). Li et al (33) and Fan and Wang (34) examined the subway shield construction safety risk and collected the safety risks based on the framework. Above all, the four frameworks mentioned earlier were aligned with the total quality management theory of "man-machine-material-methodenvironment."…”

“…As for the weight-determining method, earlier research selected the analytic hierarchy process (AHP) to determine the weight system. For instance, Li et al (33) selected AHP to calculate the weights of safety risks when investigating the safety risks in slurry balancing shield construction. Gradually, some more objective techniques were introduced to mitigate the subjectivity in determining the weights.…”

“…As for the safety risk measurement, previous literature can identify many quantitative methods. The fuzzy comprehensive evaluation method is widely applied in the evaluation of shield construction safety risks (33,35). For instance, Ren et al (35) chose this method to assess the total shield construction safety risks when being adjacent to an existing building.…”

Numerous subway projects are planned by China's city governments, and more subways can hardly avoid under-crossing rivers. While often being located in complex natural and social environments, subway shield construction under-crossing a river (SSCUR) is more susceptible to safety accidents, causing substantial casualties, and monetary losses. Therefore, there is an urgent need to investigate safety risks during SSCUR. The paper identified the safety risks during SSCUR by using a literature review and experts' evaluation, proposed a new safety risk assessment model by integrating confirmatory factor analysis (CFA) and fuzzy evidence reasoning (FER), and then selected a project to validate the feasibility of the proposed model. Research results show that (a) a safety risk list of SSCUR was identified, including 5 first-level safety risks and 38 second-level safety risks; (b) the proposed safety risk assessment model can be used to assess the safety risk of SSCUR; (c) safety inspection, safety organization and duty, quicksand layer, and high-pressure phreatic water were the high-level risks, and the onsite total safety risk was at the medium level; (d) management-type safety risks, environment-type safety risks, and personnel-type safety risks have higher expected utility values, and manager-type safety risks were expected have higher risk-utility values when compared to worker-type safety risks. The research can enrich the theoretical knowledge of SSCUR safety risk assessment and provide references to safety managers for conducting scientific and effective safety management on the construction site when a subway crosses under a river.

“…(2) SR relevance calculation Unlike HR, SR is more inclined to the joint impact of the execution effect of two or more link tasks on another. Fuzzy hierarchical analysis [23][24][25] is considered to measure the effect factor of each link task on its acted task, that is, to calculate the SR correlation between link tasks from a functional perspective.…”

Most existing risk prediction methods focus on constructing risk element sets and analyzing their uncertainties but do not deeply explore the correlation types and intensities of factors, resulting in large errors in the comprehensive risk prediction results. In this paper, a new integrated risk prediction method is proposed based on the correlation types of tasks in defense task planning and execution. The approach mainly includes the following steps: First, based on the difference of the sequence and mode of action of link tasks, three correlation types (hierarchical, synergistic, and independent) are defined among them, and various correlation measurement techniques are proposed to model these abstract correlation relations and provide data basis for constructing risk decision graphs. Secondly, the rotation extraction strategy is introduced to excavate the internal correlation law between link tasks and generate their hierarchical topology to ensure the rational distribution of their hierarchy positions in defense missions. Then, the intra-layer risk weight is determined based on the centrality of each node in the topology structure, and then the comprehensive risk prediction weighting graph is constructed. Finally, the path analysis is used to assess the rationality of the hierarchical topology structure of the link tasks, and the validity of the proposed method is verified using the test sample set. The results show that compared with other approaches, the predicted results of the proposed method more closely approximate the actual outcomes.

The government of China has planned numerous metro projects, and with more metros, undercrossing of bridges can hardly be avoided. Metro shield construction when undercrossing a bridge (MSCUB) frequently takes place in complicated natural and social contexts, which often makes the construction process more susceptible to safety accidents. Therefore, it is crucial to look into the safety risk during MSCUB. This paper identified the safety risk factors during MSCUB by using a literature review and expert group evaluation, proposed a novel safety risk assessment model by integrating confirmatory factor analysis (CFA) and fuzzy evidence reasoning (FER), and then selected a project case to test the validity of the suggested model. The study results show that (a) a safety risk factor list for MSCUB was identified, including four first-level safety risk factors and thirty-seven second-level safety risk factors; (b) the proposed safety risk assessment model can be used to measure the risk values of the overall safety risk of a worksite, the first-level safety risk factors, and the second-level safety risk factors during MSCUB; (c) environment-type safety risk factors and personnel-type safety risk factors have higher risk values during shield construction when undercrossing a bridge; (d) when compared with worker-type safety risk factors, manager-type safety risk factors are the higher risks. This study can enrich the theoretical knowledge of MSCUB safety risk assessment and provide references for safety managers for conducting scientific and effective safety management on a construction site when constructing metro shields undercrossing a bridge.
