Abstract

The bearing mechanism of bridge pile foundation in high-steep rock slopes is much more complex than that in the flat. In the basis of theory research and model experiment made by previous scholars, then the software of finite element method is used on numerical analysis in this paper, which systematically discusses the distribution of body force of pile, the displacement in pile top and situation of pile’s thrusting force distribution caused by the soil (rock) around the pile under the combined load, the negative impact of combined load on pile stability was also discussed, which can guide engineering practice.

Keywords: Bridge pile foundation, combined load, high - steep rock slopes, finite element method.
