| 中文摘要: |
| 介绍了新开发的防护结构动力有限元分析程序DIASS系统。该系统装有空爆冲击波荷载数值自动生成器,并可将基础土壤模拟为饱和多孔介质模型,采取多重子结构技术进行结构与土体相互作用的动力分析。文中利用该程序系统进行数值试验,给出若干初步结论。 |
| 英文摘要: |
| In this paper, the protective structure finite element analysis program system DIASS is introdueced. In this program system, the ground loading of shock wave from air explosion can be automatically simulated, and the foundational soil can be treated as two-phase saturated porous medium. The multi-level substructure technique is used for the dynamic finite element analysis of interaction between soil and structure. The numerical test is given,and some concldusion are obtained. |
