Research On Security Assessment Of Prefabricated Buildings Based On Cloud Model

With the stable development of the economy and society,the transformation and optimization of the industrial structure,the shortcomings of the traditional construction mode of the construction industry are becoming more and more obvious.The traditional building construction mode has high energy consumption and poor weather resistance,which seriously violates the concept of green development and is difficult to meet the people’s growing housing demand and the needs of the country’s current construction industry development.Prefabricated building construction has many advantages such as sustainable development,resource saving,and relatively short construction period.However,with the development of prefabricated buildings,the problems of construction safety have gradually emerged,and the analysis and safety evaluation of safety influencing factors have gradually become the research topics of many scholars.Construction safety is a prerequisite to ensure the healthy development of the construction industry.Factors such as unsafe behavior of construction personnel,harsh environment,and imperfect systems make the situation of construction safety severe.Therefore,there is an urgent need to carry out research on construction safety evaluation to provide a reference for the construction safety management of prefabricated buildings.This thesis summarizes the relevant theories of prefabricated buildings,safety evaluation and management,and analyzes the importance of construction safety factors through the ANP method,and determines the weight distribution coefficients of the construction safety factors through the AHP-entropy weight method.The traditional evaluation method takes into account the randomness of safety issues,cites the concept of the cloud model,and constructs a safety evaluation cloud model based on related theoretical concepts,evaluates and analyzes an example of a prefabricated construction project in Huaibei City,and proposes based on the results of the safety evaluation Countermeasures and Suggestions.First,based on the theoretical analysis of the cause of the accident,the text mining method was used to extract the construction safety factors,and the preliminary identification list was obtained,and the evaluation index was analyzed and screened,the safety evaluation index was determined,the construction safety evaluation system was constructed,and the safety was analyzed by the ANP method.The relationship between factors.Each factor group in the construction safety index system contains different factors,and these factors interact to affect the safety status of the entire project.Then,use network analysis methods to analyze the importance of security influencing factors,sort out and sort the importance of security influencing factors,and provide a basis for the final decision of key security influencing factors.In this research,this thesis analyzes the practicability of the weighting method in the safety evaluation of prefabricated building construction,and determines the comprehensive weight of the subjective and objective comprehensive weighting method.Finally,taking a prefabricated building project in Huaibei as an example,by proposing the concept of cloud model theory,an evaluation cloud model can be established for safety evaluation.Based on the safety evaluation results,corresponding countermeasures and suggestions are proposed,and the scientific evaluation index system is effectively verified.The practicality of the cloud model and the practicality of the cloud model provide a reference for the construction safety management of prefabricated buildings.Although this research has certain theoretical significance and application value for the safety management of prefabricated buildings,due to limited personal knowledge,time and energy,the selection of construction safety evaluation indicators is not comprehensive enough,and the construction safety evaluation system is not complete;combined with AHP-Entropy method can make up for the shortcomings of related methods,but it is impossible to analyze all the influencing factors of related prefabricated buildings,and there are still insufficient accuracy.Some factors are eliminated because the data is too small,which will lead to a certain deviation of the data and affect the related The completeness of the factors.There are still shortcomings in the thesis research,so further exploration and strengthening are needed to seek more reasonable and effective research methods.
