| 摘 要： | 在人类工程活动诱发下，老泥石流堆积体上的地质灾害尚未引起人们的充分注意。以川藏线二郎山隧道西引道公路别托段穿越的老泥石流堆积体为例，介绍其形成演化过程和物质结构特征，分析沿线各地质灾害点的成因，总结在这类流堆积体上进行人类工程活动时地质灾害的成灾机理及防治对策。

| Abstract: | The hazard of old accumulation of debris flow that occurred under the factors induced by engineering activities of human beings still hasn＇t aroused people＇ s attention. The Bietuo old accumulation of debris flow where the Bietuo segment of west approach road of Erlang Tunnel on Sichuan-Tibet Highway is selected as a case to introduce it＇ s evolution and it＇ s fabric character, then analyze the mechanism of the geological hazards along the highway, and finally, generalize the hazard effect and the corresponding prevention and cure measure when taking activities of engineering on old accumulation of debris flow. |

| Keywords: | old accumulation of debris flow geological hazard mechanism of hazard prevention and cure measure |
