摘　　要：主要介绍了大规模倾倒滑移边坡工程研究成果 ,同时也讨论了开挖与边坡的稳定性、边坡岩移监测与治理措施。扼要分析了引起此类边坡变形、失稳灾害的主要影响因素。基于FLAC数值模拟技术和底摩擦模型试验 ,深入分析了该边坡的变形、破坏发展 ,以及其破坏机制 ,其成果已应用于工程实际。The recent study on slope engineering of large-scale toppling-sliding has been briefly introduced and the applications of mining and slope stability, slope monitoring and measurement also discussed in this paper. The deformation and the instability disaster is related, and the main influence factors are further explored. Based on the FLAC element numerical simulation and the floor friction model , the deformation and failure development and its failure mechanism of the slope are deeply analyzed in this paper. Many research results have been used in the design and prediction of the slopes in the Fushun West Open Coal Mine, and to guide mine operation in practice.
