【摘要】 两侧采用粘弹性人工边界,底部为全约束,建立合理的土与地下结构相互作用模型,通过有限元软件分析,比较研究土—地下结构相互作用分析中埋深、土层分布和结构类型等因素对地下结构抗震性能的影响。结果表明,埋深对地下结构影响比较大,选择合适的地质土层和结构类型能大大提高结构抗震性能。更多还原

【Abstract】 A reasonable model is proposed of soil-underground structure interaction with viscous-elastic artificial boundary condition on both sides and with restrictions at the buttom.By using FEM software,the effects of some key factors,such as the buried depth,the condition of soil layers and the styles of structure,on the earthquake-resistant capacity of underground structure are studied.It is demonstrated that the buried depth has great effects on the seismic response of underground structure,and the earthquake-resistant capacity of structure can be improved greatly if the soil layers and type of structure are appropriately selected.更多还原
