摘要：
Internal stability analysis of reinforced soil slope under earthquake was one of the main research contents in anti-seismic design. A method of internal stability analysis was set up based on horizontal slice method by considering the effect of reinforcement strip, depending on the characteristic of horizontal layered arrangement of reinforcement strip and selecting plotline as the internal slip surface. The calculation formula of reinforcement tension and reinforcement length were developed through deduction. The maximum tension of reinforcement strip was transferred the optimal solution to the linear programming, the maximum tension of reinforcement strip and the most dangerous plotline sliding surface were obtained using the optimal solution method which is an inbuilt function in excel 'SOLVER' add-in. The method was applied to a practical case to conduct reinforcement tension analysis, FEM with ADINA software was carried out to verify the proposed method, and the results showed that the proposed method was safe and credible for the design of reinforced slope. The calculation method provides a theoretical basis for anti-seismic design of reinforced soil slope. © 2018, The Editorial Board of Journal of Basic Science and Engineering. All right reserved.
