| 摘 要： | 在土-结构动力相互作用分析中,考虑地基分层的影响是非常重要的。虽然国内外学者在这方面已经进行了大量深入细致的研究,但是目前仅有极少一部分可应用于工程实际的简化计算方法。基于不同理论,根据不同方法分析地基分层对地基刚度的影响,分析结果可供改进我国动力机器基础设计方法时参考。

| Abstract: | It is important to estimate the influence of layered soil in soil-structure interaction analysis.Although a great number of investigations have been carried out on this subject,there are very few practical methods without complex calculations.The effect of layered soil on stiffness of block foundations is evaluated by several methods.The result could be referred in improving the methods of the dynamic response analysis of machine foundations. |
