Abstract: In order to ensure safety of tunnel construction, a concept of safety resilience in tunnel construction was put forward based on characteristic of resilience theory. First, considering characteristics of tunnel engineering, engineering geology, emergency management and other factors, evaluation index system of tunnel construction safety and toughness including 9 indexes was determined from resilience attributes of resistance, adaptability and recovery capability. Then, based on ideal fuzzy matter-element, evaluation model of safety resilience in tunnel construction was established. Finally, with reference to Dagala tunnel, resilience rating was class Ⅱ, which was low. The results show that Dagala tunnel system is less able to resist external intrusion and prevent disasters, low level of toughness. Evaluation results of safety resilience in tunnel construction based on ideal fuzzy matter-element are consistent with actual conditions of project.

Key words: tunnel construction, safety resilience evaluation, ideal fuzzy matter element, evaluation model, resilience level
