【摘要】 千枚岩倾倒体陡坡地质状态稳定性差、地质灾害严重发育,是危害最大的地质类型之一。采用桩基工程不仅能加强千枚岩倾倒体陡坡的稳定性又能提高地基承载能力,是处理这种地质状态有效的基础方法。结合某渡槽基础加固方案,利用ADINA软件建立考虑千枚岩倾倒体陡坡地质与桩基受力耦合的复杂性桩-千枚岩三维有限元模型,进行10个模型4种工况的对比分析。分析研究表明,倾倒体滑移对桩基变形,特别是水平变形影响很大。该研究成果可为工程提供参考。更多还原

【Abstract】 Phyllite toppling steep rock slope are poor stability and serious growth of geologic hazard,it is one of the great geologic hazards.Piles base can enhance the stability of phyllite toppling steep rock slope and the foundation capacity,it is the effective base project for these geologic condition.According to the reinforce project of aqueduct base,3D ADINA finite element model of coulping piles-phyllite rock is made,10 piles base in 4 conditions are analyzed.The analysis shows that the drift of toppling takes great effect on pile displacement,especially for level displacement of pile base.The study can take some reference for the same engineering projects.更多还原
