Abstract
Through the summary of relevant literature summarized, arrangement the influence factors of construction safety risk assembly and construction safety risk factors of assembly type table, through the construction safety risk factors of assembly type table, using the system dynamics theory to build the prefabricated construction risk identification feedback model. In order to analysis the importance of factors affecting the safety risk of assembly building, according to the influence factors and factors of type table recognition feedback pattern from the qualitative (using feedback loop analysis method) and quantitative (AHP) to analysis importance of the construction safety risk factors of assembly. The conclusions obtained by the two methods are the same, and the most important ones are human factors, followed by technological factors, and finally environmental and institutional factors. Finally, according to the conclusion of the importance analysis, this paper puts forward some suggestions on the risk management of the assembly type building from four aspects of human factors, process factors, environmental factors and system factors.
