摘　　要：对川藏公路南线八宿—林芝段沿线山地灾害的工程地质调查表明,滚石对公路的危害性非常突出,鉴于滚石事件自身的特点应将之作为一个专门的灾种给予高度的重视。通过对滚石灾害的影响因素分析,给出了相应的灾害评价方法,并对19个滚石灾害点进行了灾害评价。针对灾害的相对严重程度,对各段滚石区防护措施的设置提出了初步建议。Engineering geological investigation on mountainous hazards along Basu-Linzhi section of the south line of Sichuan-Tibet highway, is conducted, which indicates that rockfall hazard is extremely serious and should be treated as a special kind of hazard with great attentions. By analyzing influence factors of the hazard, an assessment approach is presented, with which 19 rockfall sites are assessed. Countermeasures are suggested according to relatively hazardous levels at a rockfall site.
