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 分別采用基于剛體極限平衡理論的條分法和基于神經網絡的人工智能理論判別黃土邊坡穩(wěn)定性;又采用基于彈塑性理論的有限元數值模擬,進一步探討了黃土地區(qū)邊坡失穩(wěn)的影響因素及其滑坡變形機制。
