| 摘 要： | 研究表明:地震作用下土体的动力特性及变形特性与超静孔隙水压力的发展变化密切相关,因此,在土体动力分析过程中考虑孔隙水压的影响是非常必要的。本文通过对基本方程的推导,借助于大型有限元软件ABAQUS,进行了饱和土体在动力作用下孔隙水压变化的数值模拟。计算结果表明,ABAQUS完全适用于此类问题的数值模拟,并且稳定性和收敛性较好。

| Abstract: | Researches have shown that soil's dynamic responses and deformations mainly depend on the variance of the pore pressure.So the effect of the pore pressure rise and the effective stress decrease of the soil should be considered.In ABAQUS a porous medium is modeled by the conventional approach that considers the medium as a multi-phase material and adopts an effective stress principle to describe its behavior.In this paper the fundamental equations are derived and the finite element software ABAQUS is adopted to calculate the time history of pore pressure.Finally,two numerical examples of saturated soils subjected to surface cyclic loading are presented to illustrate the validity of ABAQUS. |
