Research on the Mechanism of Safety Risk Influencing Factors in the Construction of Prefabricated Building

Abstract

In order to scientifically study the construction safety risk transmission mechanism of prefabricated building, reduce the incidence of construction safety accidents and control key risk factors; a safety risk mechanism model combining the adversarial interpretive modeling ISM and MICMAC method is proposed to deal with the construction risks of prefabricated building. By analyzing the construction characteristics of prefabricated building, studying the risk sources and reading a large amount of literature, the construction safety risk influencing factor system is summarized. Based on the AISM method, a complex relationship analysis of risk indicators is conducted, a multi-level recursive structure model is formed, and the MICMAC method is applied to identify the high kinetic and high dependent factors of construction safety risks. The results show that workers' safety awareness and safety protection ability are the two most important direct causes triggering construction safety risks; construction scheme design is the most relevant factor in the system structure; reasonable construction schedule and management attention to safety issues are the deep root factors affecting construction safety risk management. All of these results give reference and guidance to construction risk management of prefabricated building.
