摘要
该倾倒变形的发育特征较复杂,其内部、底界和后缘深部的变形破坏类型分别为"倾倒蠕变"、"倾倒滑移"和"倾倒弯折"。岩体倾倒变形的形成与演变经历了4个阶段:卸荷回弹-倾倒蠕变,层内拉张-切层张剪破裂,弯曲-折断变形破裂和底部滑移-后缘深部折断面贯通破坏。
The deformation presents complex development characteristics as the deformation types of its interior, base bounda- ry and back edge are respectively ＂toppling-creep＇, ＂slip-toppling＂ and ＂toppling-bend/fracture＂. It passes four evolution stages like unloading rebound-toppling creep, extension within layers-strain-shear rupture, bend fracture deformation rupture and bottom slip-joint failure of deep back edge fracture surface.
