Kunming Social Stability Risk Essment Of Rban Rail Transit System Research

Urban rail transit project is important for the public transportation infrastructure, its characteristics is through the center of the city zone, large investment, long construction period, large impact, if the preparatory stage neglected the analysis of the impact on the surrounding environment and residents, decision-making stage nor fully consider the risk, in construction and operation stage is may lead to group events, to society caused negative effects. Therefore, scientific assessment of possible risks to social stability, develop a reasonable prevention and control measures, to ensure the project smooth implementation, the maintenance of a harmonious society is very necessary.Social stability risk assessment is an important part of project risk management, there is no unanimous approval of the urban rail transit project social stability risk assessment system, urban rail transit in Kunming is in a period of accelerating the development of explore to establish a conforms to the situation in Kunming social stability risk assessment system has very important practical significance.In this article, the author summarized and learning from the domestic and foreign scholars on social stability risk assessment research results in the field, according to the actual situation of Kunming urban rail transit construction, operation and management, on the basis of the relevant theory, study and put forward in Kunming urban rail transit project social stability risk assessment system, and to the second phase project of Metro Line 2 as an example verify the feasibility of the evaluation system and operability.First, according to the actual project, using appropriate methods, carry out a survey of risk; secondly, the construction of social stability risk assessment index system framework, to establish ANP network analysis model and evaluation index value using expert investigation method to evaluate the, accurately identify social stability the main risk factors; third, using single factor risk estimation method estimated the probability and impact of the major risk factors, assessment of the project initial risk level; fourth, propose the risk response plan and work out measures to prevent and resolve the main risk factors; finally, a comprehensive evaluation of the project implement the risk response planning after the risk grade of the proposed opinions and suggestions.
