Abstract:The safety risks of prefabricated concrete structure in the construction phase are identified through field research and conference discussion, and are quantitatively evaluated by using Bayesian network. The results show that the probability of prefabricated components instability during hoisting is the highest, followed by prefabricated components toppling, and the violent sloshing of prefabricated components during hoisting. To deal with these safety problems, concrete risk control measures are proposed from a microcosmic perspective of site management, design and construction coordination in project and a macrocosmic perspective of development environment in industry. A multi-angle and multi-stage construction risk prevention and control mechanism is constructed, which will provide reference for construction safety management of prefabricated concrete structure.
