Monitoring and earlv warning indicator svstem is set un hased on actual condition of a certain rock slopeand the method of constructing the warning indicator system. Considering the uncertainty of indicators were uncertainty, the analytic hierarchy process (AHP) method which is relatively subjective, and the information entropy method which is objective, are applied to calculate the weights for the slope monitoring and early warning system. Also, the unascertained mathematics theory is utilized to compute the uncertain weight information of the factor and indicator layers. Ultimately, the credibility of slope stability is about 92％. The calculated results are consistent with those of slope safty monitoring. Therefore, this comprehensive evaluation method of slope monitoring - warning introduced is scientific and reliable.%根据预警指标体系构建方法,充分考虑了某岩石高边坡的实际情况,收集了大量的边坡地质资料和现场监测数据,构建了边坡监测预警指标体系.在此基础上考虑了指标的不确定性特点,分别采用相对比较主观的权重计算方法-层次分析法和客观方法-信息熵法对该边坡预警指标体系进行权重计算,并对指标体系因素层和指标层运用未确知数学理论进行了权重未确知信息的计算,最终判定边坡的稳定状态及其可信度约为92%.计算结果与边坡安全监测成果分析的结果一致,因此,文章提出边坡监测预警综合评价方法是科学、可靠的.
