以代表性山区高速公路项目湖南省湘西境内某高速公路一个标段的危岩体边坡为例，通过 FLAC 3D软件对危岩体边坡进行数值模拟，详细地对研究区危岩体边坡的稳定性进行了分析与评价，通过分析最终的应力、位移、剪切应变等物理量，对3类危岩体的失稳模式进行了验证，结果表明研究区2类典型危岩体（贴坡式、悬挂式）的稳定性均较差，都有脱离母岩而失稳的趋势，因此要对其进行处理。

In this paper,a potential unstable rock mass slope of a typical mountains area freeway project in Xiangxi,Hunan province was take as an example,and a numerical simulation was given to the potential unstable rock mass slope by the FLAC 3D software,analysis and evaluated the dangerous rock mass slope in detail,through the final physical quantities of stress,displacement,shear strain and so on, checked the instability mode of the three kinds of potential unstable rock mass,the result shows that po-tential unstable rock mass of the embankment type and suspension type are unstable,both of them have the trend of instability,so we should give a processing to them.
