中文摘要：

边坡滑移时，位于陡坡段的桥梁基桩相比抗滑桩受力特性更为复杂。在合理模拟滑动面的前提下，进行了陡坡段桥梁基桩受力特性的参数对比室内模型试验。通过获取加载过程中桩身最大弯矩、桩顶水平位移及地面处基桩变位等关键指标，对不同加载方式、基桩自由长度、基桩剐度的基桩受力特性的各主要影响因素进行了探讨。试验结果表明，基桩产生的较大弯矩与水平位移主要由水平荷载引起，桩身最大弯矩随基桩自由长度的增加急剧增长，而随基桩刚度及边坡坡度的提高增长幅度较小。研究成果对揭示陡坡段桥梁基桩与周围边坡作用规律具有一定参考价值。

英文摘要：

The loading characteristic of bridge pile in steep slope is more complex to that of slide resistant pile as the slope sliding, so an influence factors compassion model test is carried out based o the rational simulation of slide surface. The maximum bending moment of pile shaft, displacement of pil head and displacement of pile on the ground is obtained in the test, so the major influence factors to th loading characteristic of bridge pile such as loading, pile rigidity, free length above the ground and slop angle is studied deeply. The results shows, that bending moment and lateral displacements of piles are caused by lateral loading mainly, and the maximum bending moment is grow to the length of free lengt above the ground rapidly, but few to the addition of pile rigidity and slope angle. The study would b helpful to reveal interaction regulation of pile - soil in steep slope.
