Research methods: Based on the fully analyze of the risk of the railway project construction the method of Analytic Hierarchy Process and Fuzzy Comprehensive Evaluation in comprehensive appraisal for Railway Project Contract risk was detailed described. Firstly, the risks in the railway project contract including technological risks, environmental risks, personal risks, have been penetrated in to and the appraise index system was build up based on the risks analysis. Then, every risk factor was given a relatively mark by the experienced technical staff to form the estimate matrix following by the principle of analytic hierarchy process. So the significance weights of the appraise indexes were calculated. Thirdly, every risk factor was given a mark by experts consulting the criterion of risk grade, so the subjection function and subjection matrix formed. Multiplayer fuzzy comprehensive evaluation was carried on to give the final result.
