| With the rapid development of economy and urban construction in J city,the output of domestic waste is also increasing rapidly.In order to effectively control the adverse impact of municipal solid waste on the environment,J city takes waste incineration technology as the main treatment method.Due to the lack of fly ash treatment facilities in J City,the fly ash generated from the waste incineration power generation process cannot be properly disposed.The construction of this project aims to solve the problem of fly ash landfill in J City.As a waste terminal treatment facility,waste fly ash landfill is conducive to improving the harmless treatment of urban waste and saving land resources and waste treatment costs.Based on this,the Chinese government has issued a series of policies to encourage the construction of waste fly ash disposal facilities.However,mass incidents caused by waste disposal projects occur frequently,and their construction and operation may lead to social stability risks.The implementation of social stability risk assessment before construction is very important for the construction and operation of waste fly ash landfill sites.The research on social stability risk of waste fly ash landfill is limited,and there is a lack of applicable evaluation index system.Therefore,it is of great practical significance to establish the stability evaluation index system of waste incineration fly ash landfill construction project for solving practical problems.This paper combs the existing research on the social stability risk of waste fly ash landfill project,and expounds the formation process of social stability risk based on the theories of stakeholders,social conflict and risk perception.Taking the J waste incineration fly ash landfill project as an example,the social stability risk assessment of the project is studied in combination with the actual situation of the project.The research is mainly divided into three parts : In the first part,combined with case analysis and literature research,the main risk factors are identified by risk comparison table,and the social stability risk evaluation index system of J waste incineration fly ash landfill construction project is constructed.The index system includes 6 first-level indicators and 16 second-level indicators.In the second part,by comparing and analyzing different weighting methods,the G1-CRITIC method is introduced to determine the index combination weight of project social stability risk.Due to the ambiguity and uncertainty of subjective evaluation,the cloud model is used to evaluate the social stability risk of the project.Through the comparative analysis of comprehensive cloud images and the combination of cloud similarity,the reliability of the evaluation results is enhanced,and the risk level and distribution state of social stability risk are determined intuitively.In the third part,the comprehensive social stability risk assessment of J waste incineration fly ash landfill project is carried out.Combined with the comprehensive cloud map and data quantification results of the cloud model,the social stability risk of J waste incineration fly ash landfill project is determined to be a lower risk level,and the main risk factors that easily lead to social stability risk are put forward.Corresponding risk response measures.Based on the G1 method and CRITIC method,this paper determines the portfolio weight of J waste incineration fly ash landfill project,and combines the cloud model to evaluate the social stability risk of the project.The practical case shows that the evaluation model has practicability and popularization value,and can provide scientific and accurate basis for the evaluation results of the project,so as to provide service and reference for the follow-up construction and operation of J landfill project and the stability evaluation research of other similar projects. |
