摘　　要：从风险分析角度,展开对三峡库区库岸公路路基安全风险的研究.构建了基于粗糙集理论的库岸公路路基安全风险单因素估计模型,通过该模型可以针对特定路段的具体情况得出适合于本路段的各风险因素权重;进而通过对库岸公路路基各安全风险因素的分析,构建了安全风险模糊综合评价模型.且以渝巴路云阳境内白水滩至南溪段库岸公路为背景,根据该段公路的实际工程情况,对库岸安全风险因素进行了分析研究,运用已建立的数学模型对渝巴公路白南段路基进行了安全风险评价.A research was conducted upon the risk assessment of bank roadbed security along Three Gorges. Based on the rough set theory, an evaluation model of risk factors was established. A feasible method was proposed to determine the weight of the factors on the basis of an analysis of the actual bank road situation. According to the fuzzy mathematics theory, a model of risk assessment of a combination of factors was established. The information of the section of Yuba bank road from Baishuitan to Nanxi in Yunyang County was collected, and the established models were adopted to assess the bank roadbed security of Bai-Nan section along Yu-Ba road.
