不同桩间距对单排悬臂式抗滑桩土拱效应的影响

Influence of different pile spacing on soil arching effect of single row cantilever anti-slide piles

运用有限元数值模拟软件建立起抗滑桩土拱效应的数值模拟计算模型,从桩土相互作用的机理出发,分析了不同间宽比下的单排悬臂式抗滑桩土拱效应的特征,重点研究了土拱效应的空间分布规律。

Finite element numerical simulation software is used to establish the numerical simulation model of the soil arching effect of anti-slide pile.Based on the interaction between the pile and the soil,soil arching effects is studied and analyzed under different axis-axis anti-slide pile spacing,different thrust distribution form,different sizes of thrust of single-row anti-slide pile and the presence or absence of coupling beam,different stiffness of coupling beam of double-row anti-slide pile.This paper focuses on the spatial distribution of soil arching,the thrust pile back suffered along the pile length,the bending moment and the shear force pile back suffered with variation of rigidity of coupling beam.
