Abstract The construction of highway mountain tunnel is affected by various uncertain factors with random and fuzzy characteristic，which cannot be exactly analyzed by current risk assessment method. This paper proposes the fuzzy-analytic network process(F-ANP) which is composed by Delphi method，analytic network process and fuzzy comprehensive evaluation. Based on the analysis of the whole process in the construction of the highway mountain tunnel，a synthetic evaluation index system for the construction of highway mountain tunnel is established. A fuzzy relation matrix is established by evaluating the evaluation index with expert investigation，by using Delphi method to compare and using triangular fuzzy number to represent the judgment matrix，a fuzzy super matrix is established with the analytic network process，by evaluating its limit matrix can obtain the comprehensive weight，then obtain the level of construction risk. Finally，empirical research to Longtouling tunnel shows that the method is reasonable and practical，it can provide reference to risk analysis for future similar projects，ensure construction safety and reduce potential losses.
