Research On Risk Evaluation And Control Of Prefabricated Building Construction Stage

At this stage,China's energy conservation,environmental protection,sustainable development and other concepts are constantly deepening the hearts of the people,in line with the development of the times,assembly-style buildings have also become the focus of attention.Compared with traditional cast-in-place buildings,prefabricated buildings have the advantages of less construction pollution,reduced noise,and shorter construction period.With the emergence and rise of the assembly-type production mode,the traditional construction site chaos,waste of resources,backward technology and other phenomena have been changed.At the same time,it is of great significance to effectively control the safety risk in the construction stage of prefabricated buildings,and to put forward different requirements for safety management from traditional buildings.Therefore,this paper introduces the intuitionistic fuzzy analytic hierarchy process to study the risk evaluation and control in the construction stage of prefabricated buildings,and establishes the risk evaluation model in the construction stage of prefabricated buildings.In this paper,the significance and background of the research on the risks in the construction stage of prefabricated buildings are described,and its development status is analyzed.Secondly,it summarizes the related theories of construction and risk management in the construction stage of the prefabricated building,and defines the risk characteristics and meaning of the prefabricated construction stage,and expounds the risk management process of the prefabricated construction stage.,roles and steps are expressed.Thirdly,the characteristics of prefabricated building construction are analyzed,and the risk evaluation index system of prefabricated building construction stage is established by fault tree analysis.The risk evaluation model of prefabricated building construction stage is constructed by using intuitionistic fuzzy analytic hierarchy process.Finally,combined with actual engineering cases,the evaluation index system and risk evaluation model established above are applied to the cases,and effective measures of safety risk control and control in the construction stage of prefabricated buildings are proposed,which provide certain reference value for the risk management of future prefabricated building construction.
