Abstract：As a key node in the development of social productivity,major projects bring about not only development of economy,livelihood and the whole society,and a number of risks concerning laws,policies,resource security and environmental security as well. In order to ensure the healthy development of economy,social harmony and stability,and realize classified risk pre-warning,utilizing systematic analysis method and risk management theory,we develop a pre-warning model of social stability risk for major projects based on three-dimensional risk classification model,as low as reasonably practicable( ALARP)and other risk classification technology. Taking the project of XX civil airport as an example,18 risks of5 types are identified,however,through risk classification and risk pre-control,we find that as long as taking corresponding risk control measures,the overall social stability risk is within the acceptable range and environmental security risk is to be intensively monitored.
