Abstarct: Underground spaces are also associated with high risks because of their high uncertainty in geotechnical environments. Most accidents and incidents in these structures are often associated with uncertainty, so the development of risk analysis and management methods and prevention of accidents is essential. More recognition of factors affecting the implementation process can pave the way for this purpose. Risk rating of projects is a key part of the risk assessment stage in the risk management process of each project. Various multi-criteria decision-making methods, as a quantitative approach, are used to allow them to be used in the risk rating issue of each project. In this study, a new model for risk management of the metro line 3 of Mashhad is provided with the help of game theory and multi-criteria decision-making methods. baxsed on the answers of specialists and experts to the prepared questionnaires, various risk groups identified using TOPSIS and AHP multi-criteria decision-making methods have been ranked. Accordingly, the group of economic risks as the most important risk and social risk group are ranked as the least significant risk in both methods. In the following, the appropriate response to the main risks of the ratings is proposed baxsed on the modeling of the game theory and ranked in terms of importance. Also, the worst risk scenario in the project is identified and the appropriate responses for this state are also expressed in order of importance. The results indicate that the risk of financing problems was identified as the most significant risk in this project, and other risks were ranked in importance in the next ranks. As well as, the use of new financing methods at times of credit scarcity and project financial problems is also considered as the most important response to the risk in this project.
