ABSTRACT

This study evaluated the phase relationship among the input motion, ground response, and pile response, which is a key consideration in the analysis of the kinematic–inertial interaction for piles. Dynamic centrifuge tests were conducted on single and group piles embedded in slopes of dry sands. Test results showed that the single pile moved in the opposite phase with the ground movement, whereas the group piles moved nearly in phase. The phase relationship was significantly affected by rocking motion. Therefore, the kinematic force acted as a resistance to the single pile and an additional load to the pile group.

基于位移相位关系的斜坡单桩和群桩的运动学和惯性相互作用

摘要

本研究评估了输入运动、地面响应和桩响应之间的相位关系，这是分析桩的运动-惯性相互作用的关键考虑因素。对嵌入干沙斜坡的单桩和组桩进行了动态离心机试验。试验结果表明，单桩与地面运动的移动相位相反，而群桩的移动几乎是同相的。相位关系受到摇摆运动的显着影响。因此，运动力作为对单桩的阻力和对桩组的附加载荷。
