摘要
在 1 995年的日本阪神地震中 ,地铁工程结构发生前所未有的破坏 ,其中柱的破坏尤为严重。人们通常认为中柱的破坏是由水平地震力引起的 ,但地铁结构的有些震害现象至今无法得到圆满的解释。采用冲量理论分析竖向地震力对地铁结构中柱破坏的影响 ,能较好的解释中柱破坏的震害现象。这说明竖向地震力对地铁工程结构的破坏有显著影响。
During the 1995 Hyogoken Nanbu earthquake, there were severe damages to subway structures, especially to the center column. Ordinary horizontal earthquake is the main cause of collapse of center column, but so far no damage has been explained satisfactorily. In this paper, impulse theory is used to analyze the influence of vertical earthquake on the center column, which can best explain the damage. The research result shows that vertical earthquake plays an important role in damage to subway structures.
