Anti-skid supporting structure and method for resisting impact of landslide-debris flow
The invention relates to the field of water conservancy project foundations, in particular to an anti-skid supporting and retaining structure and method for resisting impact of landslide-debris flow, and is characterized in that the anti-skid supporting and retaining structure comprises two or more anti-skid structures and a supporting and retaining structure, and the anti-skid structures are arranged at the positions, facing the landslide, of the toe of the landslide; each anti-skid structure comprises a first dam body, a ground anchor and a first NPR anchor cable; the number of the supporting and blocking structures is more than three; the retaining structure and the anti-skid structure are arranged in parallel and staggered in a penetrating manner; each retaining structure comprises a second dam body and a second NPR anchor cable; the anti-skid structure and the supporting structure are arranged in a staggered mode to form an anti-skid supporting structure system, and multiple impacts of landslide-debris flow can be resisted. According to the anti-skid supporting and retaining structure, the impact effect of large deformation impact of a rock-soil body on the supporting and retaining structure is reduced through deformation motion energy of landslide-debris flow, the anti-sliding and anti-overturning stability of a dam body is improved, and the damage range and degree of multiple times of impact of disasters are avoided or reduced.
本发明涉及水利工程基础领域，具体涉及一种抵御滑坡‑碎屑流冲击的防滑支挡结构及方法，其改进之处在于，防滑支挡结构包括防滑结构和支挡结构，其中：在滑坡坡脚且面向滑坡的位置设置两个以上防滑结构，每个防滑结构包括：第一坝体、地锚和第一NPR锚索；支挡结构，设置三个以上支挡结构；支挡结构与防滑结构平行且错位穿插设置；每个支挡结构包括：第二坝体和第二NPR锚索；防滑结构和支挡结构的错位设置构成了防滑支挡结构体系，能够抵抗滑坡‑碎屑流的多次冲击。本发明提供的防滑支挡结构，利用滑坡‑碎屑流的变形运动能量，降低岩土体大变形冲击对支挡结构的冲击作用，提高坝体的抗滑移抗倾覆稳定性，避免或降低灾害多次冲击的破坏范围及程度。
