| 摘 要： | 从易滑地层、断层和结构面等几个方面分析了谭家坪滑坡的形成条件，在此基础上详细地分析了谭家坪滑坡的变形破坏机理，并对谭家坪滑坡的稳定性作了评价与预测，研究表明，谭家坪老滑坡是由于河流侵蚀作用加剧、河谷深切、岩体内部构造残余应力释放、回弹、松驰，导致卸荷裂隙生成和软弱结构面贯通，加之水动力作用强烈，当剪应力大于垂向应力的情况下而形成的；白岩沟滑坡和白水沟滑坡则是谭家坪老滑坡的局部复活。

| Abstract: | Conditions forming Tanjiaping landslide are analyzed from several aspects which are easily sliding stratum, fault and discontinuities. Based on these, deformation and destroy mechanism of Tanjiaping landslide are analyzed in detail. From all of the above analysis, the conclusion is drawn as follows that the old landslide forming hy the down-cutting progress of the river and the intensive release of geo - stress in the slope and the new landslides are the old landslide's locally revival. Finally, the stability of Tanjiaping landslide is analyzed and rational harnessing proposals are put forward. |
