| 摘 要： | 本以某大型筒仓结构为例，考虑到散粒体-结构-地基的相互作用，利用部分集中质量-筒仓耦合相互作用法，对弹性地基上的筒仓结构（包括单体筒仓和筒仓群或排仓）进行了多种工况、系统的有限无动力分析计算。经与刚性地基上的筒仓动力响应的比较，得出以下结论：在对地基施以相同的水平激励时，弹性地基上筒仓的动力响应大于刚性地基上筒仓的动力响应；刚性地基上群仓的动力响应大于单体仓的动力响应；弹性地基上单体仓的动力响应大于群仓的动力响应。

| Abstract: | Considering the interaction between bulk solid, structure and its foundation, a systematic finite element dynamic analysis on silo structures on elastic foundations is presented in this paper. Large silos including single silo and silo mass are calculated by using the coupling method of partly concentrated mass and silo. The results from this study are as follows: given a same impulse to the foundation, the dynamic response of single silo on elastic foundation is stronger than that of single silo on rigid foundation. The dynamic response of silo mass on rigid foundation is stronger than that of single silo on rigid foundation. The dynamic response of single silo on elastic foundation is stronger than that of silo mass on elastic foundation. |
