程海断裂带金沙江段滑坡群的发现
|
摘要
程海断裂带金沙江段处于云贵高原西部、青藏高原东南缘,为中国西南地区的活动构造区,内、外动力地质作用显著。经野外调查发现,主要的地质灾害类型为滑坡,且主要集中分布在大路底以南的程海断裂带西盘,即达旦河右岸岸坡约10.8 km范围内。存在5个巨型滑坡,方量均在1 G以上,属巨型滑坡。在野外调查的基础上,着重阐述了滑坡的发育特征、形成机制,为地质灾害的治理提供科学依据。
The Jinshajiang segment of Chenghai fault is located in the wester part of Yunnan-Kweichow Plateau,Southeast rim of the Tsinghai-Tibet Plateau,which is the most tectonically active region in southwest China,the internal and external geological processes are significantly.Through field geological investigation,it’s found that the major local geohazard type is landslide,and mainly distributed in the west wall of Chenghai fault that is located the south of Daludi village,namely the right bank of Dadan river about 10.8 km range exist five giant landslide,party is more than 1 G stere,are belong to the giant landslide.On the basis of field investigationm,emphatically expounds the development characteristics of landslide,formation mechanism,which can be provided as scientific information for prevention of geological hazards.
