| 摘 要： | 从坡体结构、变形破裂特征和地质环境条件,研究该隧道弃渣填方路基,发现其滑坡为圆弧形破坏.对滑坡体稳定性的定量和定性分析预测,天然条件下滑坡体潜在不稳定,地震、暴雨及水库正常蓄水条件下,将失稳破坏.建议补打钢管桩至滑面以下进行治理.

| Abstract: | The filled roadbed is studied in terms of its structural,deformational and geological conditions,with the discovery of its circular deformation.The quantitative and qualitative analyses indicate that it is potentially unstable under natural conditions and will be destabilized as a rainstorm or earthquake occurs,or the water in the reservoir reaches the normal level.It is proposed that the landslide be treated with steel-pipe piles. |
