A Risk Evaluation Method for Fatigue Damage of Airport Concrete Runway

Abstract

Fatigue damage of airport runway is an important factor affecting airport safety management. To recognize the fatigue failure risk factors of airport concrete runways, an integral analysis of the internal and external causes of the fatigue failure of runways was conducted, which extracted 18 risk factors. The evaluation results of risk factors were calculated by the threshold, expert scoring, and G1 method, the comprehensive evaluation results of concrete runway risk were obtained by layer-by-layer coupling. Results show that the calculated comprehensive risk evaluation value of fatigue failure of airport concrete runways by the proposed method is consistent with the engineering objective practical value, and can be applied to the risk evaluation of another airport concrete runway. The comprehensive risk evaluation value of concrete runway failure in the case study is 0.49, indicating certain risks of fatigue failure. Engineering and management measures should be adopted by risk factors with large evaluation values to control the fatigue failure risks. The conclusions obtained from this study provide a novel method to fatigue failure risk evaluation of airport concrete runways and an airport risk management idea for reference.
