摘要
上海轨道交通1号线某区间U型槽段紧邻沪闵高架2号匝道,列车引起的振动几乎未经地层吸收即传到高架桥桩基。通过数值分析,研究了地铁列车振动对沪闵高架2号匝道桩基的动力影响,获得了列车荷载作用下沪闵高架2号匝道桩基的运动规律。
Shanghai-Minhang （HuMin） elevated highway bridge is adjacent to Shanghai Metro Line 1, the vibration caused by train is directly transmited to pile foundation. Through numerical analysis, this paper makes a study of the dynamic response of pipe foundation of HuMin elevated highway bridge, obtains the regulation vibration of pile foundation under the dynamic load caused by metro train.
