摘　　要：结合具体工程,从土—结构相互作用模型出发,利用粘性边界条件,采用时程分析法,对高烈度地震区双线公路隧道衬砌在地震作用下的反应进行数值模拟,并对模拟结果进行分析讨论,得出了高烈度地震区公路隧道地震动力响应的一般规律及隧道衬砌抗震的薄弱环节,并提出了相应的建议.Based on soil-structure dynamic interaction model, highway tunnel under seismic load is simdated using FLAC3D in this paper. The boundary effect is taken into consideration and the time domain history method is applied. The results are analyzed and the common rules of seismic dynamic response of highway tunnel are concluded, moreover, the weakness on tunnel lining is found and advises are also proposed in this paper.
