| 摘 要： | 强震中,液化土体在重力作用下往往发生水平扩展流动,对桩基础造成了严重破坏,因此有关液化土体流动对桩的影响及其之间的动力相互作用,一直是岩土工程领域研究的热点。通过模拟振动台实验,将这一过程简化为三维的单桩模型进行计算。经过对某一固定流速土体流动的计算,分析得到液化土横向流动中自身的孔隙水压力、变形以及对桩的内力和位移的影响规律。

| Abstract: | During strong earthquakes,liquefied soil under gravity frequently has horizontally spreading deformation which causes serious damages of pile foundations.Therefore,the influence of soil flow on pile-soil interaction and piles＇s earthquakes,liquefied soil under gravity frequently has horizont internal force and deformation is always the hot spots in geotechnical engineering.By simulating shake-talbe experiments,the three-diimensional single-pile model is simplified to the calculation of laterally spreading soil in unit velocity,during which the laws of pore water pressure,deformation and internal force,deformation are discussed. |
