Research On Engineering Safety Evaluation Based On Third Party

With the rapid economic development of our country,construction has become an integral part of market economy in China,Construction has become an integral part of market economy in China,China became the world's superpower infrastructure investment,Annual production value of the construction industry continues to grow.However,with the rapid development of China's construction industry,also produced a large number of safety accidents.Each year,thousands of people died in the engineering safety accident,causing a direct economic loss of billions.Construction engineering safety production problem has become the core content in the field of construction in our country.How to reduce the accidents of engineering safety has become the main target of the scholars in our country.Due to the inherent characteristics of many elements such as the construction industry,the complex construction work environment,and the low level of the operating level,the new technology,new technology,new materials and other natural features,it has brought a great challenge to China in the field of engineering security.In recent years,our country's government and scholars have made a breakthrough in the study of safety management.The research of the third party's project safety assessment is based on the development of safety assessment method,and has introduced the independent third party,Scientific,impartial,independent safety evaluation of the constructionsite.Start from the construction hazards identification,and focus on checkingand prevention of accidents,and comprehensive assessment of potential risk factors that may cause the consequences of the hazard.On the basis of the safety level of the building,provide the corresponding safety accident prevention measures.This paper first analyzes the present situation of domestic and foreign research on t he field of engineering safety evaluation,and further studies the development history of t he construction safety evaluation,and introduces the research contents and methods of thi s paper.Check out our scholars in the field of safety engineering research literature,anal yzes the type of accidents that occurred in China in recent ten years,summed up the co nstruction projects of common security incidents:mechanical injury accident,fall accident,collapse and object against accidents,analysis of evaluation of common safety methods,co:mparing the various methods studies,summed up the fuzzy integrated evaluation metho d.Based on the analysis of the types of common accidents in China,the main causes of the accident are studied in detail,and the main risk factors affecting the safety of engine ering are obtained:human factors,mechanical factors,safety management factors and env ironmental factors.Through the analysis of building production characteristics,combined with engineering safety accident caused,established the security evaluation system with 4 secondary indicators and 18 third-grade evaluation.This paper introduces the process of c alculating the weight of analytic hierarchy process and the steps of using fuzzy evaluatio n method in detail,and establishes a comprehensive evaluation model.Combined with en gineering example,apply the fuzzy comprehensive evaluation method in practical example s,calculating index weight and single factor membership degree.Establish a comprehensi ve evaluation matrix and evaluate security situation in the project instance.Obtained the evaluation results of engineering safety in good condition,and gave the corresponding re ctification opinions.Finally summarizes the engineering safety evaluation of the third part y,and the application prospect of this method in the field of engineering safety were dis cussed.
