摘要
川藏公路巴塘至林芝段位于我国青藏高原东南部,该地区是现今地壳运动十分强烈的地区之一,地形起伏强烈,气候变化多样,因此地质灾害十分发育,川藏公路就穿过这样一个复杂的地区。为查明公路沿线的地质灾害分布情况,90年代初,地矿部航空物探遥感中心沿川藏公路进行了彩色红外航空摄影,比例尺为1∶6万。通过彩色红外航片的解译及野外实地观测,圈定出滑坡、泥石流及崩塌等灾害现象,并对这些灾害的强度、活动性及其对公路的影响进行分析,最后对灾害成因及治理方法提出了建议。
The middle part of Chuanzang Highway, nearly 900 km 2, is located in southeast border of Tibetan plateau in which there was heavy crust movement during the geological history, especially in Quaternary, and there are rough landscape and weather. So the geological hazard are popular in forms and scopes. In order to investigate the distribution of the hazard along the highway, a project of aerial color infrared photography was made by CRSG in the beginning of 90's. The image interpretation of geology had done with the photos. The characteristics and shape of landslides, rockfalls and mud flows, and etc. was analyzed and a proposals were promoted for protection of geological hazards.
