| 摘 要： | 本文对桩-土相互作用问题中的层土效应分析采用原始的无限连续分层介质模型,以避免目前各种人工有限边界的影响,可更好地反映动力相互作用的内在机理。文中采用的半解析无限元方法能较好地实现这一模拟,所需计算工作量较少,适用于需进行桩土分析的工程。

| Abstract: | In this paper, the soil is treated as an infinite continuous layered medium in analyzing pile-soil interaction problems in order to avoid deficiencies in some of the current methods in which artificial boundary is placed at some finite boundary for the better representation of the essential mechanism of dynamic interaction. The semi-analytical infinite element method used in this paper reflects better this model and reduce computational efforts. Hence, it is suitable to analyze pile-soil interaction problems in engineering practice. |
