摘要我国既有露天矿山边坡失稳绝大多数发生在台阶边坡或组合台阶边坡，这种总体边坡普遍偏安全、台阶边坡或组合台阶边坡普遍偏不安全的事实说明，用相同的设计安全系数标准评价总体边坡稳定性与台阶边坡稳定性的传统方法有待完善。提出边坡稳定性评价精度概念，建立稳定系数误差与边坡设计安全系数相关关系，在此基础上构建近期静态精度与评价期静态设计安全系数、长期动态精度与服务期动态设计安全系数的关系，为边坡设计安全系数的不确定性问题提供一种确定性解决方案。提出大型露天矿山边坡稳定性等精度评价方法，按照结构面空间位置与边坡部位相匹配、结构面规模与边坡规模相匹配的原则，系统全面地找出控制边坡稳定的关键性结构面及其组合，开展边坡稳定性分级分析，将边坡划分成“稳定的”和“可能破坏的”两种类型；针对可能破坏的总体边坡、组合台阶边坡和台阶边坡，建立边坡稳定性计算模型，找准边坡潜在滑移面所对应的结构面及其潜在滑移方向，开展岩体结构面抗剪强度精细取值，进行边坡稳定性定量计算，实现大型露天矿山边坡稳定性等精度评价，消除稳定系数随机误差以降低边坡稳定性计算的误差水平，提高边坡稳定性评价精度；统一边坡稳定性评价标准，采用相同的设计安全系数评价不同级别边坡的稳定性；均衡不同级别边坡的稳定协调性，确保总体边坡、组合台阶边坡、台阶边坡达到相同的稳定状态。研究表明，大型露天矿山边坡稳定性等精度评价的综合效果，台阶边坡最好、组合台阶次之。

Abstract：Most of slope failures of existing open-pit mines in China occurred in composite-bench slopes and single bench slopes but other types of slopes are safe generally，which indicates that the traditional method using the same standard of safety to evaluate the stabilities of different kinds of slopes needs to be improved. The concept of assessment accuracy of slope stability was proposed. The relationships between the error of stability coefficient and the safety factor，between the recent static accuracy and the static safety factor during the evaluation period and between the long-term dynamic accuracy and the dynamic safety factor during the service period were presented. A deterministic solution for the uncertainty problems in determining the safety factor was proposed. A method of equal accuracy assessment was presented. The spatial locations of rock joints should match the corresponding parts on the slope，and the size of rock joint should match the size of slope. All the slopes were systematically analyzed to find out the key joints and their combinations. The slopes were classified into the stable and potentially unstable ones using the graded analysis method. The calculation models of slope stability for those unstable slopes were established，the potential sliding surface and sliding direction were exactly determined，and the shear strength of rock joints was determined precisely to raise the computational accuracies. The random errors of the stability coefficient are eliminated to reduce the error level in slope stability calculation with the method of equal accuracy assessment. According to the results of the case study with the method of equal accuracy assessment，the single bench slopes have the best results，the composite-bench slopes the second.
