Risk Level Comprehensive Evaluation Model of High Rise Building Construction Based on FAHP

In view of the frequent occurrence of safety accidents in the process of building construction in China, this paper puts forward the use of fuzzy analytic hierarchy process (FAHP) to analyze and comprehensively evaluate the construction safety. Firstly, we make a comprehensive comparative analysis on the methods of safety risk assessment of buildings, and sort out the index system of safety assessment combined with current situation of accident management in construction site. Then the paper establishes the risk evaluation model of building construction based on fuzzy theory and AHP, and evaluates the safety problems of construction project systematically and scientifically. Finally, through the implementation on an engineering example, the feasibility and practicability of the model are verified, which is proved to provide a new idea for the management and control of high-rise building construction safety.
