| 中文摘要: |
| 复杂滑坡可能存在一个以上的潜在剪出口或滑动面，以重庆市巫山至巫溪公路寨子沟滑坡为例。逐级对其潜在剪出口进行支护，运用极限平衡法计算，分析其潜在剪出口支护后滑坡稳定性系数的变化。研究表明，第一剪出口支护后，仍然存在次级滑动面，再对次级滑动面进行支护，以此类推，寻找出所以小于设定稳定安全系数的滑动面或剪出口，对其进行支护，阻止滑带从潜在剪出口的剪出，提高滑坡的稳定性，确保滑坡加固措施安全。 |

| There may be more than one potential shear outlet or sliding surface in complex. Landslides, takingWushan to Wuxi highway as an example. Potential shear outlet is supported successively.,and the stability coefficient of the landslide after the potential shear support is analyzed by limit equilibrium method. The research showthe secondary sliding surface was still existed after the first shear outlet is supported. Then the secondary was supported, and so on. Only when finding out all the sliding surface or the shear outlets, support the slipper from the potential cut off the cut,improve the stability of the landslide,to ensure the safety of landslide reinforcement measures. |
