Abstract: The composiotion elements of the side-slope landscape and security system of the mountainous freeway were deeply analyzed from the point of rides personnel , and the indexes that affected the coordination degree of freeway side-slope landscape and safety were determined. Group analytic hierarchy process method was introduced to evaluate the index weight. UC-win/ Road was utilized to establish the three-dimensional dynamic model of the side-slope landscape , and then the dynamic simulation was also carried out. So the coordination degree level of side-slope landscape and security was obtained , which could judge the coordination degree level of side-slope landscape and security. Finally , the case study shows that the proposed method is feasible , which has a good application value.

Key words: mountainous freeway, side-slope, coordination degree of landscape and security, 3D dynamic model

摘要： 从驾乘人员的角度分析了山区高速公路边坡景观安全系统各组成要素，确定了影响公路边坡景观与安全协调 度的指标，引人群层次分析法确定评价指标权重。应用UC-win/Road道路景观规划软件对公路边坡景观建立三维 模型，并进行动态仿真模拟，得到公路边坡景观与安全的协调度等级，以判断边坡景观安全协调性。实例分析表明: 方法可行，具有较好的应用价值。
