摘要
Abstract
The seismic performance of the bridge pile structure system supported by anti-slide pile in a representative steep slope section of a railway line is studied by means of large shaking table test.The sizes of the model and prototype slope are designed by using the similar principle with a scale factor of 1 ∶ 40.The test results of the sine wave and Wenchuan wave are used to analyze the seismic law of the slope model.The results show that the soil pressure between bridge pile and anti-slide pile is distributed triangularly,the anti-slide pile soil pressure is distributed in the form of "R";the slope has amplification effect on the acceleration of monitoring points;the displacement increases with the increase of seismic load.The response strengths of the anti-slide pile are greater than those of the bridge pile,indicating that the anti-slide pile has a good supporting effect on the bridge pile foundation.The research provides a good foundation for seismic design of the new structure with slope anti-slide pile and bridge pile foundation.关键词
