| 中文摘要: |
| 总结了以往对向家坡滑坡治理工作经验教训，并通过定性的工程地质分析和定量计算评价了向家坡滑坡稳定性的变化趋势，提出改建公路超挖深切坡角、持续长时间强降雨形成的空隙水压力以及滑坡内部的物质组成是导致古滑波复活进而发生滑动破坏的主要因素，结论指出该滑坡治理中需考虑膨胀岩的膨胀性和加强内外排水。 |
| 英文摘要: |
| In this paper, based on the sum-up of past experience and lesson about it, the authors evaluated the current stability of landslide and its developing tendency by means of geology analysis and mathematical calculation.It reveals that the leading factors affecting the ancient landslide revival and stability are the excavation of the foot of the slope and rise of pore water pressure and substance element inside landslide and so on.The conclusions indicate that the prevention work of Xiangjiapo Landslide need consideration of bulgy rock of distensibility and strengthen drain inside and outside the landslide. |
