摘要	In order to accurately evaluate the stability of slope reinforced by frame with pre-stress anchors under random earthquake, it was very necessary and urgent to carry out the stability evaluation method and the reliability seismic design theory. Considered the soil behind the slope as an elastomer, the dynamic calculation model of soil behind the slope was established. Regarded the earthquake acceleration as a random variable, the pseudo-excitation method was adopted to get the random seismic response of slope, and the slope seismic acceleration response spectrum was obtained. What's more, the limit state equation based on the most dangerous sliding surface and the computing method of reliability of slope stability were given. The proposed computing method was applied to an engineering example and the influence of seismic acceleration distribution characteristics on the slope stability and the change law of minimum stability coefficient was analyzed in terms of the reliability theory. The random seismic dynamic response analysis and the reliability calculation of slope stability were carried out. The effectiveness of the proposed method was verified by Monte Carlo method. The results show that the proposed analysis model with clear physical concept is a rapid, accurate and practical analysis method. The proposed method provides theoretical basis and a new computing approach for reliability calculation on slope stability reinforced by frame with pre-stress anchors. © 2017, Editorial Department of China Journal of Highway and Transport.
