  • To calculate the stability factor of reinforced earth retaining wall under earthquake, a stability analysis model was set up based on the upper bound limit theory by considering the effect of the reinforcement strip and selecting the logarithmic spiral as the integral slip surface. The stability factor equation was developed through deduction of the external power made by sliding mass gravity behind the retaining wall, the external power of earthquake on sliding mass, the internal power of soil cohesion of the potential failure surface, and the reinforcement strip on soil friction. The stability factor of reinforced retaining wall under earthquake was calculated using the genetic algorithm. The results show that after considering the reinforcement, the stability factor obtained by the dynamic model of failure surface is 1.337, which is 0.08 higher than the stability factor calculated by the method from Code for Design of Highway Reinforced Earth Engineering. This suggest, taking the anti-sliding effect of reinforcement into accout during the stability analysis is reasonable.
