摘　　要：巴东组红层是中国红层的典型代表。以湖北宜巴高速公路红层路堑边坡为例,采用定性分析与定量分析相结合的方法,对其失稳机理进行分析。结果表明:降雨作用是诱发滑坡的主要原因,并对路堑边坡治理,提出以抗滑挡墙与锚杆框架梁等相结合的加固措施,达到了较好的治理效果。Badong Red Bed is a typical representative of the red bed in China. Taking the red-bed cutting slope along Yichang-Badong Highway in Hubei as an example, the failure mechanism thereof was analyzed by the method combining qualitative analysis with quantitative analysis. The result shows that rainfall is the main factor inducing landslide; and the cutting slope is reinforced by anti-slide retaining wall and anchor frame beam, thus reaches a good treating effect.
