摘要
本文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地震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。考虑了水平和竖向地震荷载对地下结构的耦合效应 ,得出了竖向地震荷载对地下结构的破坏有重要影响的结论。
The dynamic response of underground structure under vertical and horizontal seismic load is simulated and analyzed using the FLAC code as a two dimensional explicit program based on effective stress dynamic analysis method. The code of the model used to describe soil media is programmed and connected with FLAC. The coupling effects of underground structures under vertical and horizontal seismic load are considered. The important failure effects of structure under vertical seismic load are concluded.
