摘要
通过对某公路边坡的变形破坏机理分析,表明滑坡的发生是由于坡脚的小规模开挖引发的局部变形破坏了坡体中原有的地下水排泄通道,使地下水水位抬升,从而使边坡稳定性进一步降低,造成变形破坏向坡体的上部发展,最终导致整体的滑动。稳定性计算表明,此滑坡整体稳定性差,需要作加固处理。综合分析地质条件后,选择抗滑桩和坡面护坡的方法来治理滑坡,并达到了较好的效果。
By analyzing the deformation mechanism of a highway landslide, it shows that the landslide was caused by the petty collapse at the slope toe. The groundwater table rose due to the seepage drainage destroying and reduced the slope stability and made the destroy developing to slope top. At last, the. slope slide in whole. The stability calculation result shows that the stability of the slope was low and needs some reinforcing measures. By analyzing the geology conditions, such as the anti-slip pile was used to reinforce the landslide and the effect is good. The landslide is stable and has no deformation anymore.
