潭邵高速公路顺层滑坡整治

通过对某顺层古滑坡的现场调查，分析判断出古滑坡的滑动范围、滑动面，并对滑动面抗剪强度参数进行了反分析计算。据此对古滑坡体进行了初步整治设计，实际整治时未进行防水措施，抗滑指标进一步下降，并对此时软化滑动面抗剪强度进行了计算分析。结果对K89-95段的调查分析，对此区段的切方边坡违背工程地质选线原则导致的后果进行了反思。

Renovation to Bedding Fault Landslip on Tan-Shao Expressway

On the basis of site investigation of certain bedding fault ancient landslip, the slip limit and slip plane of the ancient landslip are analyzed and judged. And antithetic analysis and computation are done to the shearing strength parameters of the slop plane. According to these, preliminary renovation is done to the ancient landslip. Since it took no consideration of waterproof measures, the index of slip prevention falls further more. In this case, computation and analysis are done to the shearing strength of the slip plane after softening. In conjunction with the investigation and analysis to section K89~95, speculations are done to the consequences arising from going against engineering geological alignment selection principle of the cutting slope in this section.
