大断面隧道结构在地震荷载作用下的动力响应分析

Dynamic Response Analysis of the Large Cross-section Tunnel under Seismic Load

文章运用了弹塑性有限元原理分析了大断面公路隧道在地震荷载作用下的动力响应分析,并讨论了不同的阻尼比、场地条件和震中距对振动响应的影响。

This article applies the elastic-plastic finite element theory to analyze the dynamic response of the large cross-section tunnel under seismic load, and it also discusses the influence of different damping ratios, site conditions and different epicantral distances on the dynamic response.
