摘要

通过管桩振动台试验,研究了管桩结构体系在地震作用下的动力响应及内力反应的主要规律。试验结果表明,管桩结构体系的加速度峰值反应在高度上呈"K"型分布,位移反应沿高度呈"S"型分布,在桩身距离桩顶5～6倍桩径处弯矩最大。本试验为管桩的抗震研究提供了试验数据,为工程设计提供了参考。
Based on shaking table test of pipe pile,in this paper several key issues about dynamic responses and internal force responses of pipe pile structural system under seismic action are studied.The results show that acceleration peak reaction of pipe pile structural system's distribution shapes "K" and displacement response's distribution shapes "S" in height.It is at the distance of 5~6 times the pile diameter from the pile top,in which there is the maximum bending moment of pipe pile.The test provides seismic research of pipe pile with experimental data,and gives some references to engineering.
