摘要
The formation mechanism of rockslide-debris flow at Yongwo-Dazhai in Guanling County,Guizhou Province,is preliminarily studied in this paper.The research results show that the structural surfaces of the slope are well developed,which surfaces include three sets of steeply inclined tectonic joints and a set of primary joints in the slope.The slope was cut into the wedge-shaped bodies by these joints.Of them a set of structural joints belong to the ancient fracture surface;it was the main controlling factors of the landslide.It concludes that the landslides could be induced by continuous drought and heavy rainfall.
