中文摘要：

露天矿边坡工程稳定性一直是影响煤炭生产安全的重要因素，为有效控制边坡失稳、确保煤炭生产安全。基于属性数学理论建立了边坡稳定性评价的熵权属性识别模型．首先，根据边坡所处的地质条件与边坡失稳影响因素，选取边坡坡高、边坡坡度、天然容重、内摩擦角、粘聚力、地震烈度与孔隙水压力比作为岩质边坡稳定性评价的指标，采用熵权法确定评价指标所占权重；其次，分析评价指标的属性测度，构建属性测度函数以计算各个指标属性测度与综合属性测度；最后，采用置信度准则对边坡稳定性进行属性识别．通过对安太堡露天矿边坡治理前后的稳定性评价，得出削坡、注浆加固与预应力锚索加固等边坡治理措施的有效性．将属性识别模型评价结果与加权平均法评价结果进行对比验证，同时将边坡稳定性评价结果与边坡监测数据对比，结果表明：熵权属性识别模型可以有效地解决边坡稳定性的评判问题，且评价结果合理，为边坡工程稳定性评价提供了一条新思路．

英文摘要：

Open pit slope stability has been the important factor that affects coal production safety. To effectively control the slope failure, ensure coal production safety, the Entropy Attribute Recognition Model of slope stability evaluation was built based on attribute mathematical theory. Firstly, according to the geological conditions and the influence factors of slope instability, the slope height, slope angle, natural bulk density, angle of internal friction, cohesion, seismic intensity and pore water pressure ratio as the rocky slope stability evaluation indicators was selected, .and the entropy method was used to determine the weight of evaluation. Secondly, attribute measurement functions was rigorously constructed to compute attribute measurement of single index and synthetic attribute measurement. Lately, the identification of stability evaluation of rocky slope was recognized by the confidence criterion. By the evaluation of open pit slope stability, we can get the result that slope cutting, grouting, prestressed anchor reinforcement are effectiveness. The assessment results agree well with the results obtained by the weighted average evaluation method. Compared the open pit slope stability evaluation with the monitoring data of the slope, the results show that： Entropy attribute recognition model can effectively solve the problem of slope stability evaluation, and the evaluation results are reasonable, and provide a new approach evaluation the slope stability.
