| 摘 要： | 为了对门架式抗滑桩的结构特性有进一步的认识和提升，进行了门架式抗滑桩三维地质力学模型试验与门架式抗滑桩结构模型试验。通过在桩身内部贴置应变片以及桩身的关键位置处放置千分表，来测量在推力荷载施加过程中，门架式抗滑桩的桩身应力变化特点及关键位置点的位移变化特征。试验结果表明：门架式抗滑桩桩前、后排桩桩顶位移大于滑动面处位移，后排桩桩身位移大于前排桩桩身位移；前、后排桩桩身内力均呈现明显的“s”型分布，桩顶应力不为零，其数值随着推力荷载的增大的而增大。

| Abstract: | The geomechanical model testing based on pile-soil interaction and structure model test of portal anti-sliding piles are conducted to study its stress mechanism. Strain gauges are pasted in internal of piles to discuss its stress features, and dial indicators are placed at key positions to analysis its displacement features. The results showed that the displacement of rear pile is larger than front pile, and the displacement of pile top is larger than the position of sliding surfaces. The stress distribution of rear pile and front pile both present the "s" distribution and the stress value of top rear pile and front pile is not null whose value increases with the growth of thrust load. |
