Moreover some random factors of orientation and frictionAngle of structural surface are considered during the stability analysis of joint rock mass.
在节理岩体的稳定性分析中，考虑了各组结构面产状和摩擦角的随机性。
2
Internal frictionAngle has a strong nonlinear relation with moisture state related saturation and a weak nonlinear relation with density state related saturation respectively.
内摩擦角和与水分状态相关的饱和度的关系是强非线性的，和与密度状态相关的饱和度的关系是弱非线性的。

Moreover, the frictionangle' s change rule and the reasons of different granules were analyzed and pointed out under the same water ratio.
