摘要
九寨沟县漳扎镇沙坝沟位于白河右岸,距九寨沟景区约20km,5.12地震后,该地段成为了泥石流爆发的高危区。通过对该区地层岩性、地质构造、地形地貌、气象水文及泥石流发生历史的调查,查明了该区泥石流发育的自然环境、形成条件和泥石流基本特征,为泥石流防治工程方案选择和防治工程设计提供了基础资料。
Shaba Valley is located on the right bank of the Baihe River, about 20 km apart from the Jiuzhai Valley spots. Here became a frequently-occurring district of mud-rock flow after the 5.12 earthquake. This paper deals with basic characteristics and causes of the mud-flows based on study of lithology, structure, geomorphology and meteorology in this region.
