Aimed at a slope engineering in Nanjing , it mainly studied the stability analysis and reinforce-ment schemes design on soil slope .Using the MIDAS/GTS software which was based on the strength re-duction finite element method, the slope stability is analyzed, three dimensional finite element model is established and simulated for anchor anti-slide piles combined with framed beams anchor supporting schemes, and the results are analyzed for pile internal force , displacement and the overall slope stability , then it verifies that the way to optimize the supporting scheme was effective and reasonable on the premise of assuring the safety.Finally, the reinforcement design scheme of slope is summarized and some mean-ingful conclusions are obtained , and it has reference for similar engineerings to a certain extent .
