| 摘 要： | 对金丽温高速公路K81高边坡进行接触大变形有限元动态数值分析.结果表明,路堑边坡开挖,导致滑面的法向应力减小、抗滑力下降,是引起古滑坡复活的根本原因.研究结果也说明了接触大变形有限元分析方法可以较好地分析潜在滑面的力学作用,是研究滑坡的滑动机理的有效方法.

| Abstract: | According to dynamic numerical analysis of Jin-Li-Wen expressway K81 high-slope by means of large deformation of contact FEM, it is stated the main reason that reviviscence of ancient slide was caused by decrease of normal stress on slide-plane and descending of skid resistance resulting from cutting-slope excavation. The result revealed that contact FEM analysis of large deformation is an effective method by which sliding mechanism of landslide was researched; meanwhile mechanical action of potential slip surface was analyzed better by this way. |
