| 摘 要： | 借助有限元模拟软件,对有无软弱夹层的两种岩质边坡进行计算比较,分析两种边坡变形位置和破坏程度的差异;通过对多不同厚度软弱夹层岩质边坡数值模拟计算,研究软弱夹层厚度、倾角对边坡稳定性的影响;探讨结构面倾角与边坡稳定的关系,进而提出一定条件下采用结构面倾角作为边坡稳定性判据的思想.

| Abstract: | Using FEM software,two kinds of rock slopes with weak sandwich or not are computed and compared in order to analyze the differences in the deformation position and degree of damage with different rock slope numerical simulations,the influences of thickness,obliquity on slope stability are analyzed;the relations between obliquity and slope stability are discussed.Furthermore,the theory that obliquity is applied to judge slope stability under certain conditions is put forward. |
