中文摘要：
为了实现对非均质边坡稳定性的全面表征与系统评价，提出了一种针对非均质边坡的“多级次”评价方法。这种方法以强度折减理论为基础，首先对岩土体进行多次局部强度折减，得到边坡不同深度、不同岩层控制的多级潜在滑动面；然后运用极限平衡法进行各个潜在滑动面的稳定性计算，即可得到边坡不同深度、不同级次的稳定性系数。这种方法在确定多级滑动面的过程中充分利用了强度折减法客观性的优点，避开了极限平衡方法主观性的缺点，折减所得滑动面更能反映边坡在重力作用下的变形破坏过程，优于滑弧法搜索结果。通过规则模型的验证及实际边坡的应用，证明这种方法对于综合评价非均质边坡的稳定状态是有效的，并可为边坡的治理、监测设计及施二[：提供指导。
英文摘要：
In order to make a clearer description for assessing the overall steady state of an inhomogeneous slope, a multi-level method based on strength reduction is proposed. Initially, the multi-level potential slip surfaces can be found by using the local strength reduction of the rock mass at different depths or different strata, then, the slope stability analysis using the limit equilibrium method is conducted for each potential failure surface. Finally, the slope stability coefficients at various depths and levels can be obtained. This method makes full use of the objectivity advantage of strength reduction and avoids the subjectivity disadvantage of the limit equilibrium method in the course of determining multi-level potential slip surfaces. The slip surfaces obtained by this method can better reflect the failure process of slopes under the action of gravity than those by other methods. The results by the proposed method are better than those by the arc method. A case study proves that this method is effective for the comprehensive stability analysis of the inhomogeneous slope, and that it can provide guidance for the treatment, monitoring design and construction of slopes.
