| 摘 要： | 本文对永窝、大寨滑坡-碎屑流形成机制进行了初步分析,认为斜坡坡体结构面发育,主要存在3组陡倾构造节理以及一组原生节理,将岩体切割成楔形体,其中一组构造节理形成的古断裂面,为滑坡形成的主控因素;连续的干旱,然后持续的强降雨,诱发滑坡的发生。

| Abstract: | 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. |
