摘　　要：以十天高速公路汉中段工程为依托,通过实地调查、分析评价,研究确定了公路边坡失稳的模糊综合评价所需的因素集、评价集、隶属函数及因素集的权重,构建了模糊综合评价模型,对公路边坡失稳进行了综合评判,确定出了典型灾害点的危险度等级。评判结果为:该边坡稳定性为高危险度,必须加固处理。Depending on Hanzhong Section of Shiyan-Tianshui Highway, the weights of factor set, evaluation set and membership functions required by fuzzy comprehensive evaluation of highway slope instability are studied and defined, through which the fuzzy comprehensive evaluation model is established to carry out comprehensive evaluation of slope instability and confirm the hazard grade of typical disaster places. The result shows that the this slope＇s stability is in high hazard grade and have to be reinforced.

关 键 词：十天高速公路 边坡失稳 模糊综合评判 高危险度 加固处理
