青岱公路穿越古滑坡稳定性分析与治理研究

当公路必须穿越古滑坡时，通过分析原始边坡的稳定性、开挖后边坡的整体稳定性，认为古滑坡在自然状态下是稳定的，对规划公路进行开挖后边坡整体是稳定的，但公路上方边坡的稳定性无法满足要求，通过削坡、支挡等方法治理，可满足设计要求。工程实践证明，边坡稳定性情况良好。

Stability Analysis and Treatment Study of Qingdai Highway crossing Ancient Landslide

When highway had to pass ancient landslide, the stability of the original slope and the integral stability after excavation are analyzed, thus it is deemed to be stable under natural situation and the whole slope along the planning highway after excavation is stable as well ; however, the stability of the upper slope along the highway can not meet the requirement, but through some treatments, such as earthwork clearing, retaining etc. , the design requirement could be met. The practical work has proved that the slope stability is good.
