Study On The Evaluation Of Safety Influencing Factors In The Construction Site Of Assembly Building

With the rapid development of China's national economy,the construction industry has become an important part of our economy and become a pillar industry.After the rapid development of the process,building industrialization has been derived,prefabricated architecture has been highlighted in the eyes of people.However,the construction safety management of prefabricated buildings is negligent,hazard source identification and safety risk evaluation are not comprehensive enough,resulting in safety accidents,resulting in life danger and property loss.Therefore,it is necessary to pay attention to the work of project safety production,and analyze and evaluate the factors affecting the safety of prefabricated construction site from the perspective of safety.By comparing and analyzing the existing comprehensive evaluation system of building safety in China and the world,this paper tries to find out the main causes of accidents in the construction industry of our country,and probes into the characteristics and dangerous sources of prefabricated building construction.This paper analyzes the consequence,casualty degree and probability of prefabricated building construction,and hopes to find a way to improve the level of construction safety management by analyzing the comprehensive evaluation system of prefabricated building safety.The construction safety evaluation model of prefabricated building is constructed by using analytic hierarchy process,expert scoring method,entropy weight method and fuzzy comprehensive evaluation method.In this paper,an example project is selected,and an evaluation index system is constructed according to the factors affecting the safety of the construction site during the construction process of the project,and it is hoped that the method of empirical analysis can be adopted.Further evaluate the safety level of prefabricated construction.
