| 摘 要： | 本文系采用边界单元法对半无限地基进行三维动力分析.分析表明,在半无限体的三维动力分析中,该法远比有限单元法优越得多.文中有关基础与地基间相互作用的动力分析问题的讨论,仅限于三维刚性基础和均质线弹性(或粘弹性)土体.本文将动力问题用边界元法表示成时间域中的公式,并以逐步积分法求得相应的动力反应.最后,将圆形和矩形刚性基础的计算结果与理论值相比,两者十分吻合.

| Abstract: | In this paper,the boundary element method is used in dynamic analysis of semi-infinite foundations.This method is better than FEM for dynamic analysis.The present discussion of the dynamic analysis soil-foundationinteraction is limited to 3-D rigid foundations and homogeneous linear elastic or viscoelastic soil bodies.In this paper,the dynamic problem is formulated in the time domain with the boundary element method and tile dynamicresponse is obtained through step-by-step integration.A comparision of the calculated results for circular and rectangular rigid foundations with the theoretical values shows that they are in good agreement. |
