| 摘 要： | 在现行计算方法中,通常采用不平衡推力法设计抗滑桩,尽管国内外岩土工程技术人员做了不少的工作使该方法得到了很大的发展,但仍有许多不完善的地方。基于ABAQUS有限元软件,结合有限元强度折减法对抗滑桩加固的边坡进行三维数值分析。通过桩-土相互作用的机理分析和稳定分析,揭示了埋入式抗滑桩相对于全长桩而言更具经济性和合理性,同时就桩间距对加固效果的影响进行了分析。研究表明,采用有限元强度折减法可以考虑桩-土之间共同作用,得到不同桩长和桩间距条件下治理工程的稳定性,计算结果更合理。

| Abstract: | At present,Imbalance Thrust Force Method(ITFM) is often adopted in the calculation of designing anti-slide piles.Geotechnical engineers at home and abroad have done a lot of work to improve the traditional calculating methods recently,while there are still lots of defects.This paper conducts 3-dimension analyses on the slope reinforced with anti-slide piles based on the FEM program of ABAQUS combined with strength reduction FEM. Through the mechanism analysis and stability analysis of the interaction betwee... |
