Safety risk assessment model of prefabricated building construction based on improved matter-element extension method
The construction of prefabricated buildings projects faces high complexity and risks during the con-struction process,making safety risk assessment of great practical significance.Taking prefabricated building construction projects as the research object,a prefabricated building construction safety risk assessment model based on improved matter-element extension method is proposed.Firstly,a set of evaluation index system for safety risk assessment in prefabricated construction is constructed,and the weights of each evaluation index are allocated through structural entropy weight method to ensure the objectivity and scientificity of the assessment process.Then the traditional matter-element extension model is improved by replacing the maximum member-ship degree principle with the proximity principle.Finally,the model is validated using a prefabricated building project in Qingdao City as an example.The validation results show that the improved model can effectively ad-dress the lack of consideration for fuzziness and randomness in construction safety risk assessment,intuitively reflect the project's risk tendency and trend,and provide a scientific basis for early warning and control of safe-ty risks in prefabricated building construction.
