英文摘要	Considering soil nailing effects on stability of a soil side-slope, according to the damage model of its slip surface, the limit equilibrium theory and the pseudo static approach, its seismic stability model and a searching model of its most dangerous slip surface were set up. The function relationship between stability coefficient and the center of its circular slip surface was derived. Errors should be induced in calculating horizontal seismic inertial force and anti-sliding moment according to vertical slice. The seismic stability analysis method of the slope protected by soil sailing was improved using horizontal and vertical slice methods. Calculation of the stability of the slip surface was carried out using genetic algorithms. It could avoid getting in local minimum in optimal searching. Using object-oriented programming language VC ++, a computing program was made to realize the optimization. Finally, the method was used to a case study. The results showed the proposed method is credible.
