Construction And Application Of Safety Risk Assessment Method For Commercial Farm Houses In Yunnan Province Based On Cloud Model

With the continuous improvement of living standards in rural areas,in order to improve their own quality of life and living environment,it has become a common phenomenon for rural residents to build and renovate farm houses in rural areas.The nature of most farm houses has also changed from self-use farm houses to public ones.Agglomeration of operational farm houses.In recent years,a large number of operational farm house safety accidents have occurred,with frequent occurrences,which have seriously threatened the lives and property safety of residents in rural areas.The research topic comes from the research work of the operational farm house safety risk assessment carried out by the Department of Housing and Urban-Rural Development of Yunnan Province.Aiming at the shortcomings of traditional farm house safety risk assessment that commonly use the expert "empirical evaluation method" to achieve qualitative assessment,the research on the safety risks of operational farm houses in Yunnan Province is carried out with the aim of establishing a fast,accurate and targeted operational farming Housing safety risk quantitative assessment methods and models.The paper mainly carries out the following tasks:(1)By searching and reading a large number of domestic and foreign literatures on the safety assessment of civil buildings,summarizing several commonly used risk assessment methods in the safety assessment of civil buildings,and analyzing the advantages and disadvantages of these risk assessment methods,choose one This is a quantitative assessment method with good practicality in the safety risk assessment of operating farm houses in Yunnan Province.(2)Aiming at the uncertainty of the security risks of commercial farm houses,this article regards the security risks of commercial farm houses as an uncertain complex system.Based on the risk theory,summarizes and summarizes the current security risks and safety risks of commercial farm houses in Yunnan Province.Risk factors,and taking the common and typical commercial brick-concrete structure farm houses in Yunnan Province as an example,construct the Yunnan Province commercial brick-concrete structure farm house safety risk assessment index system.(3)Based on the advantages of the traditional fuzzy comprehensive evaluation method to achieve quantitative evaluation in the uncertain system risk assessment,the fuzzy comprehensive evaluation method is used to construct a quantitative evaluation model for the safety risk of the operating brick-concrete farm house in Yunnan Province,and the practical application is carried out to verify this The feasibility of the quantitative assessment model in the safety risk assessment of commercial brick-concrete structure farm houses,and the analysis and summary of the shortcomings of the assessment model.(4)Use the cloud model to improve the quantitative evaluation model constructed by the traditional fuzzy comprehensive evaluation method,carry out practical application and analysis,and compare and analyze the evaluation results obtained with the quantitative evaluation model constructed by the traditional fuzzy comprehensive evaluation method to prove the improvement based on the cloud model The latter quantitative evaluation model is more scientific and reasonable.Finally,according to the different severity of safety accidents of different types of operating farm houses,a quantitative evaluation model based on the correction of risk coefficients is proposed.
