Abstract: In order to study the mechanism of how deeply-buried piles reinforce slope, five groups of large scale physical model tests were conducted in the lab of Chinese Northwest Railway Academic of Science. In the experiments, pressure endured by deeply-buried pile in different places is not the same, which indicates that the experiment can’t be simplified to plane strain problem. Finally, several groups of model tests are simulated by three-dimensional finite element of elastic-plasticity. The result is almost identical to the experimental data, this justifies the application of three-dimensional fem method to design deeply-buried pile.

Key words: deeply-buried pile, three-dimensional fem, slope reinforcement, model experiment
