摘　　要：针对目前高边坡安全稳定性评估主要考虑单项监测项目及不能综合考虑几项或多项监测项目等问题,在对安全监测资料进行分类汇总,并充分考虑影响边坡稳定的各种因素后,建立了边坡稳定综合评价多层次物元体系,对评价指标进行预处理后,运用物元可拓模型评价了边坡的安全等级。实例应用结果表明,该方法科学地构建了边坡安全稳定评估体系,合理量化了评估指标,可操作性强。At present, high slope stability evaluation is mainly only considering individual monitoring project while not considering several or more monitoring project. Giving full consideration to various impact factors of slope stability, slope multiple evaluation information matter element system is established by classifying the data of safety monitoring. After pretreating evaluation indexes, matter-element extension evaluate model is used to compute the slope safety level. Example results show that the method is scientific for construction evaluation system of slope safety and stability and quantifies evaluation indicators reasonably with simplify operation.
