摘要
本文采用模态分析法对贮液构筑物与地基相互作用问题进行了分析、探讨、建立了计算模型,进行大量的对比计算,数值结果表明,考虑贮液构筑物与地基的相互作用以后,贮液构筑物的动力特性发生了较大变化,地基的影响对较低频率尤为明显。
The model analysis for liquid-storage structure-foudation problem is studied in this paper, and establish the analyzing model, some calculations by contrasting modal are done. The numerical results show that. considering such interaction, dynamic characteristics of liquid-storage structures are changed greatly, foundation have an distincter effect on frequencies.
