Force Characteristics of Anti-slide Pile of Slope under Shallow and Deep Sliding Deformations
摘要
Abstract
The reinforcement mechanism of anti-slide piles in slopes with shallow and deep weak interlayers is investigated based on numerical FLAC3D and analytical methods.The anti-slide pile reinforcement in double-layer sliding zone slopes under different deformation modes caused by weakening of sliding zone parameters is investigated,and the interaction between shallow and deep sliding bodies is examined.The results show that under the weakening of sliding zone parameters,the post-pile thrust and pre-pile resistance of the anti-slide pile on double-layer sliding slope are discontinuous at the shallow sliding zone,and in the deep-shallow layer deformation mode,the sliding of shallow sliding mass also affects the stress and deformation of the deep layer of anti-slide pile.The theoretical calculation method for the internal force of entire anti-slide pile is improved,and the improved theoretical calculation method is applied in the Majiagou double sliding layer landslide in the Three Gorges Reservoir Area.The reliability of the improved theoretical calculation method of anti-slip piles for double-layer slip surface slopes is demonstrated.关键词
