【摘要】 本文中振动台的地基基础设计 ,它属于大型三向动力基础 ,设计过程中不能简单地将这一耦合系统离散成若干个子结构 ,而应该考虑围岩介质对基础的影响。为此 ,采用相互作用的分析方法对无限地基进行合理模拟 ,从而得到较为精确的分析结果 ,运用到实际设计中去更多还原

【Abstract】 The foundation of the shaking table presented in this paper is different from the ordinary foundation.As it is a large scale three dimensional dynamic foundation,such coupled system cannot be simply discretized as several sub?structures.The influence of the surrounding soil media should be considered.A rational simulation is carried out to the infinite ground base by using an interaction analytical method.A rekltuvely accurate analytical result is obtained and such method can be applied to the practical design.更多还原
