| 摘 要： | 以南平杨真隧道工程为例，运用Midas有限元软件，模拟分析了隧道开挖对邻近高边坡稳定性、边坡变形以及滑坡的影响。结果表明:该隧道工程施工前后临近高边坡的整体稳定性、应力场、水平位移变化均较小，边坡围岩屈服区未发生明显变化。

Numerical Analysis on the Influence of Bias Multi-arch Tunnel Construction on Adjacent High Slope |

| Abstract: | Taking Yangzhen tunnel in Nanping as an example, the influence of tunnel excavation on the stability, deformation and landslide of the adjacent high slope was simulated and analyzed by Midas finite element software. The results show that the overall stability, stress field and horizontal displacement of the adjacent high slopes before and after the tunnel construction are changed slightly and the yielding area of the surrounding rock of the slope has not changed significantly. |
