摘要
在川藏公路关键段二郎山西口至康定县城长７４ｋｍ的范围内，共发育滑坡３４处、崩塌３３处、泥石 流４３处，其发育密度分别达０．４６，０．４４和０．５８个（条）／ｋｍ。分析表明，上述地质灾害的分布与该地所赋存 的地形地貌、地质构造及岩性条件等密切相关。
Comprehensive investigation and systematic research on the geological hazards beside the line from Erlang Mountain to Kangding Town have beeen conducted. It has been found that there are 34 landslides, 33 rockfalls and 43 debris flows occurred on 74km long slopes along the No.318 National Road from Erlang Mountain to Kangding Town. The average linear densities of landslide, fockfall and debris now are 0.46, 0.44 and 0.58/km respectively. Through investigation, it is evident that these geological hazards are correlated with the stratum rock property, geological structure and topographic change.
