| 摘 要： | 爆炸地震波荷载类似于天然地震波荷载，但又不完全相同。基于有效应力动力分析法，运用二维显式有限差分程序FLAC对地下结构在竖向和水平爆炸地震波荷载作用下的动力响应进行数值分析。编制了周围土体介质分析模型的程序模块并与FLAC接口。考虑了水平和竖向爆炸地震波荷载对地下结构的耦合效应，得出了一些定性的结论。

| Abstract: | Explosion seismic wave loadings are similar to seismic loadings but there are some deferences between the two kinds of loadings. The dynamic response of underground structure under vertical and horizontal explosion seismic loading is simulated and analyzed by using the FLAC code which is two-dimensional explicit finite difference program according to effective stress dynamic analysis method. The code of the model which is used to describe soil media is programmed and connected with FLAC. The coupling effects of underground structure under vertical and horizontal explosion seismic loading are considered, and some properties are gained after numerical simulating the coupling effects. |
