Abstract：In view of limitations in searching the critical slip surface of rock slope of the existing domestic and international software for limit equilibrium slope stability analyses，a new method named GA-Sarma algorithm for rock slope stability analyses is proposed. Just as its name implies，GA-Sarma algorithm is implemented based on Genetic algorithm and Sarma method. GA-Sarma algorithm assumes the morphology of slip surface to be a broken line with traceability to extend along the discontinuous surface structures，and the slice boundaries are consistent with rock mass discontinuities such as rock layers，faults，cracks，and so on. GA-Sarma algorithm is a revolutionary method that is suitable for global optimization of the critical slip surface for rock slopes.
