| 摘 要： | 人工高切坡开挖常常导致边坡失稳破坏，甚至诱发滑坡发生，为此提出了高切坡超前锚杆支护的设计新方法。超前支护锚杆能够约束边坡变形和开挖卸荷带的发展，维持边坡的稳定，对超前支护锚杆的作用机制问题进行了研究，阐述了超前支护锚杆的荷载传递特性，为超前支护锚杆设计提供了理论依据。

| Abstract: | Slope failures or even landslides are often triggered by improper excavation in high slopes cutting, whereas pre-reinforced anchor bolt presents an effective stabilization method. A new method is proposed for the design of pre-reinforced anchor bolt for retaining high cutting slopes, Pre-reinforced anchor bolt can stabilize the slope by constraining slope deformation and development of stress relief from overburden removal. The interaction as well as force transfer mechanism between bolt and rock mass are studied; and the results provide theoretical basis for the design of pre-reinforced anchor bolt. |
