Cantilever anti-sliding anchoring system and method for large landslide
The invention discloses a cantilever anti-sliding anchoring system and method for a large landslide. The cantilever anti-sliding anchoring system comprises a plurality of anchoring units arranged in a slope body, wherein each anchoring unit is composed of an anti-sliding main pile, a supporting table and a transverse anchor cable structure; and the anti-sliding main pile is an inclined pile arranged in the direction perpendicular to the sliding direction of the slope body, the supporting pile is an inclined strut arranged in the sliding direction of the slope body, the supporting pile dissipates supporting axial force through the supporting table, landslide thrust is converted into axial force, and the axial force and the foundation bearing force are balanced. Meanwhile, the transverse anchor cable structures are applied to the pile tops to control displacement of the pile tops, and therefore the whole anchoring system is coordinated in stress and deformation, the anti-sliding effect is good, stability and safety are high, and the cantilever anti-sliding anchoring system can be widely applied to rock and soil large landslides or high fill slopes and is wide in application range, high in practicability and high in generalization performance.
本发明公开了一种大型滑坡的悬臂抗滑锚固体系及方法，包括多个布设在坡体内的锚固单元，所述锚固单元由抗滑主桩、支撑桩、支承台和横向锚索结构组成。其中，抗滑主桩为沿垂直于坡体滑动方向设置的倾斜桩，支撑桩为沿坡体滑动方向设置斜撑，支撑桩通过支承台消散支撑轴力，将滑坡推力转换为轴力，使轴力与地基承载力平衡；同时，桩顶施加横向锚索结构控制桩顶位移，进而使整个锚固体系受力变形协调，抗滑效果好，稳定性和安全性较高，其可以广泛地应用于岩质、土质大型滑坡或高填方边坡，应用范围广，实用性强，推广性高。
