摘　　要：针对目前山区丘陵公路边坡危险性评估案例较少,且存在大量模糊性、随机性和不确定性因素等问题,以重庆市某段典型山区丘陵公路为例,结合实地考察情况和专家意见,对该地区公路边坡的影响因子进行深入研究分析,总结归纳了4类14项山区丘陵公路边坡灾害主要影响因子并构建评估指标体系.最后采用AHP-模糊综合评价法实现了该地形公路边坡危险性定量和定性综合评估.结果表明,AHP-模糊综合评价法与赤平投影法的分析结果基本一致,但相比只能进行定性分析的赤平投影法,AHP-模糊评价法可以进行定量和定性综合分析,评估结果更加准确合理,实用性更强.In view of that there are few cases of slope risk assessment in mountainous and hilly highway,and there are many problems such as fuzziness,randomness and uncertainty,taking a typical mountainous and hilly areas highway in Chongqing city as an example,combined with field investigation and expert advice,the influence factors of highway slope in this area are deeply analyzed.The main influencing factors of slope hazards of4kinds of14hill highway are summed up,and the evaluation index system is constructed.The AHP-fuzzy comprehensive evaluation method was used to realize the quantitative and qualitative comprehensive evaluation of the slope.The results show that the results of AHP-fuzzy comprehensive evaluation are basically the same with those of the stereographic projection method.But compared with the stereographic projection method that can only be used for qualitative analysis,AHP-fuzzy evaluation can be used for quantitative and qualitative analysis.The evaluation results are more accurate,reasonable and practical.
