Abstract:

To prevent construction safety accidents in large-scale construction projects, it is essential to develop diagnostic methods for their construction safety. The definition of a large-scale construction project and the safety diagnostic procedure were defined against the background that Xiongan New Area was in the construction peak period. By combining influencing factors such as severe weather, construction intensity, and risk control, based on the theory of risk management, life cycle, and emergency management, the risk management of large-scale construction projects was deeply studied, and the safety diagnosis method based on time variation was constructed. Based on the field investigation and data collection, the construction safety in the large-scale construction project of a certain area in Xiongan New Area was diagnosed by means of qualitative analysis and quantitative analysis, and the risk levels of various hazard categories over time were obtained. The high-incidence periods of major risks such as foundation pit collapse, scaffolding falls from height, and tower crane lifting injuries were identified to provide effective practical guidance for reducing risk loss.

Key words: large-scale construction project, construction safety, safety diagnosis, risk management, Xiongan New Area
