| 摘 要： | 基于对高桥乡窑厂坪滑坡进行的钻孔勘探、水文调查以及滑坡体的变形破坏特征分析,查明该滑坡为岩质滑坡。通过滑坡体的变形破坏迹象、运动特征,将滑坡划分为Ⅰ(剧滑区)、Ⅱ(沉陷下错解体变形区)、Ⅲ(拉裂破坏变形区)、Ⅳ(拉裂沉陷变形区)、Ⅴ(滑覆区)5个区,并判别窑厂坪滑坡开始发育时具有推移式的特点,变形启动后则逐渐转变成以牵引式为主的变形破坏模式。

CHARACTERISTICS OF DEFORMATION AND FAILURE AND FORMATION MECHANISM ANALYSIS OF YAOCHANGPING LANDSLIDE |

| Abstract: | Based on the drilling exploration,hydrographical survey and landslide body’s deformation and failure characteristics of the yaochangping landslide in Gaoqiao town,it was identified as rock landslide.According to the signs of deformation and failure,movement features of landslide body,the landslide can be divided into five zones,which contain zone Ⅰ(Giant slip zone),Ⅱ(Subsidence,dislocation,and disintegration deformation zone),Ⅲ (Tensile and failure deformation zone),Ⅳ(crack and subsidence deformation zone),Ⅴ(slip overlap zone).In summary,yaochangping landslide was discriminated that it has the characteristics of elapsing at the beginning,which gradually transformed into retrogression-based deformation and failure mode after deformation starting. |
