The purpose of this study was to investigate the risks of the Amirkabir tunnel drilling pro-ject in Iran. Materials & Methods: In this descriptive study, the tunneling process was divided into 3 phase. The data including the type of risks, their effects and possibilities were gathered using failure modes and effects analysis (FMEA). The cumulative fre-quency of risk grades was calculated, and then ranked by Pareto principles. Findings: The highest percentage of risk grades included hitting with tunneling ma-chineries and equipments, falling-down of workers and crashing of equipments. Discussion & Conclusion: Based on the Pareto diagrams, by removing or cont-rolling the risks, it would be possible to optimize the safety of Amirkabir tunneling project.
