中文摘要高切坡潜在破裂面预测与稳定性判识是高切坡灾害防治的基础。采用极限分析上限定理,结合弧形条分法思想,构建了高切坡潜在破裂面预测与稳定性超前判识方法。针对危险性高切坡,提出超前支护桩加固方法,研究了超前支护桩抗力与加固高切坡整体稳定系数、潜在破裂面之间的对应关系。结合工程算例分析,揭示了高切坡坡体抗剪强度、边坡高度、坡角以及开挖高度对高切坡潜在破裂面的定量影响,为工程建设过程中高切坡灾害防护提供了一条可行的途径。 
英文摘要The prediction of potential failure surface and the stable discrimination is the basis of prevention for the high cut slope. We use the upper bound theorem of limit analysis,combined with curved slice method to build a new method for high-cut slope. We proposed a reinforcement structure ahead of excavating which called pre-embedded
piles. Study on the relationship between the resistance provided by the pre-embedded piles and the overall stability of the high cut slope,the coefficient corresponding relationship between resistance provided by the pre-embedded piles and the potential failure surface. Combined with engineering example,this article reveal the impaction
of the potential rupture surface with the landslide shear strength,slope height,slope angle and the height of excavation. Then,a feasible way to protect the high cut slope in the construction process is provided.
