摘要
总结了近年来国内外学者对抗滑桩土拱效应的研究现状,考虑桩土之间的相互作用,建立起水平推力作用下抗滑桩土拱效应分析数值模型。运用有限元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,分析了有无连梁的双排悬臂桩、不同连梁刚度下的双排悬臂桩,重点研究了土拱效应的空间分布,桩背所受的推力沿着桩长的分布,不同连梁刚度下桩身弯矩、剪力等内力的变化规律等。
.Finite element numerical simulation 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 the presence or absence of coupling beam,different kinds of 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 sufferes with variation of rigidity of coupling beam.
