| 以娄湘公路北侧反倾边坡为实例，采用有限差分软件FLAC3D建立数值模型，对不同锚固参数下反倾边坡的变形破坏特征和锚固力加固机理进行分析，揭示了各个参数与反倾边坡滑移变形特征的响应关系。结果表明: 锚杆加固在坡底时对剪切滑移型边坡的变形起到主要控制作用，边坡抗滑移能力最高；锚杆越长，边坡变形量越小，锚杆锚固力随锚杆长度的增加而增大，边坡稳定性提高；在保持锚杆长度和锚固位置不变的情况下，锚固角增大可以使边坡锚固力增加，边坡稳定性提高，但影响很小。 |

| Taking the anti inclined slope on the north side of Louxiang Highway as an example, a numerical model is established by using the finite difference software FLAC3D, and the deformation and failure characteristics of the reverse slope under different anchoring parameters and the reinforcement mechanism of anchoring force are analyzed, revealing the response relationship between each parameter and the sliding deformation characteristics of the anti inclined slope. The results show that the bolt reinforcement at the bottom of the slope plays a major control role in the deformation of the shear slip type slope, and the slope has the highest anti-sliding capacity. The longer the bolt, the smaller the deformation of the slope. The anchoring force of the bolt increases with the increase of the bolt length, and the stability of the slope is improved. With the bolt length and anchor position unchanged, the increase of anchor angle can increase the anchor force of slope and improve the stability of slope, but the impact is small. |
