The Research On Social Stability Risk Assessment Of Waste To Energy Construction Project And Take Beijing A Project As An Example

With the growth of urban population in Beijing,the amount of urban solid waste has increased year by year.With the adjustment of the proportion about urban solid waste treatment in Beijing,the proportion of urban waste incineration has been increased.However,at present,inadequate numbers of solid waste incineration power plants in Beijing,and some the waste incineration power plants have already overloaded.In order to solve the problem of waste incineration power plants are limited,the Beijing municipal government ordered to speed up the construction of treatment facilities,waste incineration power plants but as pollution treatment plant construction projects,not smooth waste incineration,to reduce the social stability risk events caused by the occurrence of the project to carry out the project,good risk control,social stability risk assessment has important practical significance.However,China's social stability risk assessment of a late start,little research in this field,has not formed a set of suitable social stability risk assessment index system,therefore establish power project evaluation system of social stability,social stability risk assessment is carried out after the work has important practical significance for waste incineration.This thesis summarizes other scholar's experiences in related fields for social stability risk assessment index of construction through literature research,case analogy analysis.And it forms a list of social stability risk factors combined with the project characteristics of waste incineration plants through a comprehensive recognition of social stability risk of the projects.After the expert's investigation,it constructs the social stability risk assessment index system of waste incineration power projects combined with the principle of construction of evaluation index system,including 8 first class indexes and 36 second class indexes.According to comparison of the risk assessment analysis method,literature research method and other scholars in the assessment of the risk of social stability,it introduces AHP method and combined with it,constructs the social stability risk assessment model of waste incineration power projects.And it also summarizes the calculation method of social stability risk value and risk grading,forms a set of social stability risk a qualitative and quantitative assessment methods.This thesis takes Beijing A waste incineration power project as the research object,in order to ensure the social stability risk assessment model is scientific and reasonable in the field.It removes the risk factors not involved in the model,through the social stability risk investigation,identification and evaluation.And then,it builds AHP judgment matrix using the model and gets different class indexes weight sorting for the general goal at the same time on the basis of the calculation result that CR is less than 0.1 and the consistency checking.It is obtained risk value of each risk factor and the whole project by using expert marking method from rationality,validity,feasibility and controllability.And based on the calculation result,it is defined as medium risk level.It is also gives 9 main social stability risk factors and the risk response measures in order to reduce the probability of social stability risk events occurrence.The social stability risk assessment model built in this thesis is more reasonable and easy operation determined by experts.It can serve for those social stability risk assessment work in the future,also provide services and references of social stability risk assessment study in other areas.
