Analysis on Factors Influencing Mechanics Characteristics of High Slope Reinforced by Anti-slide Piles
Anti-slide pile is a kind of common retaining measure for high slope.In order to study the main factors affecting the force performance of anti-slide pile,based on Abaqus numerical simulation,the influence of pile diameter,pile length of embedded segment and pile position on the distribution of internal force of pile is studied.The results show that(1)the pile bending moment and shear force are positively correlated with pile diameter.And the anti-slide pile can significantly improve the stability of high slope,and increasing the diameter of pile is more beneficial to the stability of slope.(2)The embedded depth of anti-slide pile also has an effect on the distribution of internal force of pile.In particular,the longer the embedded section is,the greater the internal force of the pile is,but increasing the length of the embedded section can effectively reduce the displacement of the pile top.(3)The influence of pile location on the internal force of the pile shows that the closer the pile is to the toe of the slope,the smaller the internal force of the pile and the displacement of the pile top.Therefore,when the anti-slide pile is designed,the pile force and the pile displacement should be considered comprehensively.The research results provide a useful reference for the engineering treatment of high slope.
