The stability of them has an vital influence on project implementation,which is also hand in glove with discontinuity surface, for example,joints,fissure,fault and weak interbed etc.These discontinuity intersect vertically and horizontally ,which makes great difference in property between it and integrated rock.On that account,we should do deepgoing research on deformation failure mechanism and stability analysis for rock mass slopes.

节理岩体边坡的稳定性跟边坡中的不连续面的关系密切，如节理、裂隙、断层以及软弱夹层等，这些结构面纵横切割，使得岩体的性质与完整岩石大相径庭，因此，必须对节理岩体边坡的变形破坏机制和稳定性分析作深入的研究。
