| Abstract: | 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. |
