变形对边坡稳定性的影响

指出边坡自身的弹、塑性变形越大,与极限平衡法假定土体为刚体相差也将越大.鉴于此,进行了有限元圆弧搜索法对土坡在不同变形下稳定性的变化规律研究,结果表明有限元法在考虑变形方面具有一定优势,对以后的边坡稳定分析计算有一定的指导意义.

Influence of deformation on slope stability

The more elastic and plastic deformation of slope has taken place,the more premise of limit equilibrium method taken soil as rigid body is not exact.Therefore,taking research on regularity of slope stability in different deformation using FEM with arch search,the result shows FEM has an advantage when taken into account deformation,the results may assist us in slope stability analysis in the future.
