摘　　要：基于模糊数学理论,建立了边坡多层级模糊评判模型。结合某高速边坡实例,考虑到影响边坡稳定性因素的模糊性和不确定性,通过详细勘察,得到20类影响边坡稳定的主要因素,根据评判模型,采用隶属函数组法和专家法分别赋予影响因素中连续型变量及离散型变量的隶属度。通过评判模型得到的公路边坡稳定性的预测结果与实际情况相吻合,验证了该方法的合理性,为公路边坡稳定性分析提供了新的思路。Based on Fuzzy Mathematic Theory,side slope multi-hierarchy fuzzy evaluation models are established. Combining with one of the high-speed side slope examples and in view of the fuzziness and uncertainty of the influencing factors of slope stability,the paper obtains 20 kinds of major factors that influence the stability of slope by detailed investigation. According to the evaluation model,membership function methods and expert methods shall be used to give membership to continuous variable and discrete variable in the influencing factors. The coincidence between the predicting result of road slope stability and the practical situation is obtained through evaluation model,which verifies the rationality of this method and provides new thoughts for road slope stability analysis.
