The Research On The Risk Assessment Of The Ping-zan Highway Engineering On The Base Of The Fuzzy Analytic Hierarchy Process(ahp)

Due to the rapid development of expressway projects in China and the large amount of engineering projects in the expressway construction projects and longer the period and more the related matters involved in the construction period,so there are a lot of risk factors,which directly affect the construction and development of expressway projects.If evaluate the various risk factors that exist in these construction processes,ultimately take effective measures to minimize risk reduction hazards and losses in order to successfully complete the highway construction project objectives.This paper mainly focuses on the possible risk factors in the construction of mountainous expressway project,this paper first introduces the research background and significance of the project,lists the current situation at home and abroad,puts forward the main research contents and methods of this project,then introduces the definition and characteristics of expressway risk factors and the process of highway project risk assessment,The risk of expressway project is analyzed from five aspects.Then,the principle and definition and algorithm steps and advantages of AHP and fuzzy analytic hierarchy process are introduced in detail,according to the concrete situation in Pingzan expressway,the matrix of each risk factor is established by using AHP and fuzzy analytic hierarchy process.Finally,the results of the analysis are obtained.According to the calculated results,it is proposed that these risk factors should be Take macro and specific risk control methods.This paper discusses the various risk factors in the Pingzan Expressway project from the theoretical and practical aspects,the purpose is to evaluate the risks existing in the current mountainous highway project,it can adopt the analytic hierarchy process and fuzzy Analytic hierarchy process to calculate,according to the calculation results,it can quantitatively determine the main risk factors.This calculation method can promote the rapid development of mountainous highway project in our country.
