| 摘 要： | 运用FLAC3D对某建筑工程千枚岩边坡稳定性及锚杆加固后边坡稳定性进行了模拟分析，研究了锚杆长度与加固效果的关系。结果表明:千枚岩的存在降低了边坡的稳定性，利用锚杆加固后，边坡的潜在滑面向内移动；锚杆长度并非越长加固效果就越好，锚杆的长度存在一个经济值，当超过这个经济值，锚杆长度的增加并不能进一步提高边坡的稳定性。

Study on Impact of Anchor Length on Stability of Phyllite Slope |
| |
| Abstract: | In this paper, simulation analysis is performed for the stability of phyllite slope reinforced by anchors and unreinforced one by FLAC3D, and the relationship between anchor length and reinforcement effect is studied. The results show that Phyllite reduces slope stability and after reinforcing by anchors, the potential sliding surface of phyllite slope moved to the depths; the reinforcement effect does not vary with the anchor length, the anchor has economic length, and if the economic length is exceeded, increase of the anchor length cannot further improve the slope stabity. |
