摘　　要：湖北省$245巴鹤线K169＋000～K169＋200边坡为覆盖层边坡，边坡可见疑似滑坡迹象，属于湖北$245巴鹤线恩施境内15个重点地质灾害点之一．为了查明边坡稳定性及病害性质，以便对其进行进一步的研究和治理，运用工程地质分析法结合相关软件分析了该边坡的整体稳定性，发现该边坡崩坡积物堆积松散，危石分布较多，易启动．使用专业滚石计算软件RocFall计算了坡面落石轨迹，研究了边坡结构，坡面堆积体成因．分析认为，边坡整体稳定，边坡病害以危石为主．The K169 ＋ 000 - K169 ＋ 200 slope of S245 Badong-Hefeng provincial highway in Hubei is a overburden slope. It is suspected that there are signs of landslide. It belongs to one of the fifteen key geo- logical hazard survey points about the S245 Badong-Hefeng provincial highway in the territory of Enshi in Hubei. To find out the slope stability and the main slope disease for further study and governance, a study was made to analyze the the slope stability by combining method of engineering geology analysis and con- ceming softwares. The results find that the slope rockfall deposit has a loose structure and contains many critical rocks which are easy to start. ProfesSional rockfall calculation software RocFall was used to calculate the slope rockfall trace. The study confirmed the slope structure, causes of slope accumulation body and overall slope stability, as well as slope diseasemainly caused by dangerous rocks.
