Separately select and use the slice method based on rigid body theory of ultimate equilibrium and the ai theory based on neural network to justify loess side slope stability and finite element numerical stimulation based on elastoplastic theory to further research the factors of slope failure and deformation mechanism of landslide 分别采用基于刚体极限平衡理论的条分法和基于神经网络的人工智能理论判别黄土边坡稳定性；又采用基于弹塑性理论的有限元数值模拟，进一步探讨了黄土地区边坡失稳的影响因素及其滑坡变形机制。
