Research on Dynamic Risk Assessment Method for Construction Safety of Fabricated Construction Projects

For the construction safety risk assessment of prefabricated construction projects, the traditional evaluation methods are difficult to ensure the data quality under dynamic changes, which affects the reliability of the evaluation results. Therefore, this paper puts forward the research on the dynamic evaluation method of construction safety risk of prefabricated building engineering. According to the construction environment of the assembly construction project, the risk source is determined by analytic hierarchy process, the evaluation index is selected, and the weight vector of each index is calculated. After the one-time assessment, the variable weight of the weight vector is processed according to the characteristics of dynamic change, the comprehensive weight of the evaluation object is calculated, the evaluation standard cloud is constructed, the comprehensive weight is substituted into the evaluation standard cloud, and the dynamic evaluation of construction safety risk is realized in combination with the evaluation language. The experimental results show that the designed evaluation method has high data quality and can effectively evaluate the construction safety risk of prefabricated construction projects.
