【摘要】 桩—土—上部结构相互作用的研究已成为抗震工程中的重要课题,但因其相互作用的复杂性,这方面的研究并不成熟,尚需进行深入地探讨和研究。在桩—土共同作用下,就地基对上部结构的影响以及上部结构对地基的影响,这两种不同情况的相似问题进行了研究,给出了振动台模型试验设计的一般步骤。由相似理论得出了桩—土—上部结构在通常情况下的相似关系,并给出了实例分析。研究表明:试验目的不同,考虑的主要影响因素不同,主要相似关系亦不同。更多还原

【Abstract】 The study of pile-soil-superstructure interaction has become an important issue in earthquake engineering.However,because of complexity of the interactions in this area,the research is not mature.It still needs to conduct in-depth discussion and research.In this paper,two different similar problems about the impact of the foundation to the superstructure and the superstructure to the foundation are studied,and the design procedure of shaking table model test is presented.A general similar relationship of pile-soil-superstructure is obtained through the similarity theory and an example analysis is carried out.The result shows that the difference of test purposes and main considering factors leads to different similarity relationship.更多还原
