| 摘 要： | 层状岩体抗剪强度具有各向异性的特点，在分析顺层岩质边坡的稳定性与剪切滑动面方向上需要考虑 值方向性变化的影响。首先提出层状岩体 值的表达式，然后在此基础上选用一顺层边坡作为实例，分别计算分析了坡高、岩层面倾角、坡顶堆载特别是强度参数 值各向异性对边坡稳定以及剪切面方向的影响。

| Abstract: | The shear strength of layered rocks possesses anisotropic characteristics. So in studing the slope stability and shear failure orientation the changes of with the layered directions should be considered. The expression of for layered rocks are proposed. Based on the expression, taking a bedding rock slope for example, the influences of changes of slope height, orientation of cleavage plane, loads on top of slope and specially on the stability and shear failure orientation are calculated and analyzed. |

| Keywords: | bedding slope cleavage plane shear failure plane shear strength |
