With genetic algorithm and importance sampling, a new design method of runway length was put forward based on reliability theory.The reliability of long-term airport was calculated with this -4 -4 method, the calculating failure probability was 4.75×10 , and practice result was 2×10 3× -4 10 , two results were closed.The results indicate that the method is feasible in the design of runway length and safety evaluation.2 tabs, 1 fig, 8 refs.
