摘要： 为得出抗滑桩加固的边坡在不同工况下的特性变化,文中基于MIDAS三维有限元分析软件,分析了在不同弹性模量和不同堆载作用下抗滑桩边坡土体的位移应力变化。结果表明:不同弹性模量及堆载变化下,位移及应力随桩身变化不同,桩身7m处的应力及位移最大,弹性模量及堆载越高,土体土拱效应越明显,本文结论可为抗滑桩的应用提供依据。

关键词: 抗滑桩加固, 三维有限元分析, 弹性模量, 堆载, 土拱效应

Abstract: In order to obtain the characteristics of the slope strengthened by anti-slide pile under different working conditions，the displacement stress change of anti-slide pile slope soil under different elastic modulus and different loading was analyzed based on Midas 3dfinite element analysis software.The result shows that under different elastic modulus and pile load changes，the displacement and stress vary with the pile body.The maximum stress and displacement are at 7mof the pile body.The soil arching effect varies obviously with the load and modulus of elasticity.

Key words: strengthened by anti-slide, MIDAS three-dimensional finite element analysis, elastic modulus,
pile load, soil arching effect
