In recent years, many large scaled tunnels, like the Kouksa Tunnel, with complicated construction have emerged in China. The multiple factors, including intricate topography and weather conditions, all make the potential risks highly uncontrollable during tunnel excavation. The researching group made comprehensive assessments to geological risks of the Kouksa Tunnel through the fuzzy theory, and drew the conclusion that its risk belonged to level three, as a medium one. By assessing geological risks, it will be helpful for the construction unit to take measures to prevent high-risk geological disasters and ensure the safety of tunnels.
