以某地下立体交叉隧道结构为例,探讨了不同方向相同地震波分别激励下衬砌厚度对该类结构动力响应的影响。依据土与结构动力相互作用理论,针对切片的二维计算模型对地下隧道结构进行抗震分析不能完整体现结构地震响应规律的不足,应用有限元软件ADINA建立了土-地下立体交叉隧道群三维整体有限元计算模型,对该地下结构进行了地震时程分析。计算结果表明：衬砌厚度增加,结构位移与应力响应有所减小,加速度响应有所增加,且影响程度不一。计算结果可为类似结构抗震设计提供必要依据。

Explored the influence of the lining thickness on structural dynamic response in different directions and the same seismic wave incentives,took an underground interchange tunnel structure for example.Based on soil and structural dynamics interaction theory,and aiming at the deficiency of the two-dimensional computational model which is often used cannot completely reflect the earthquake response rule of structural,established a whole three-dimensional finite element model using finite element software ADINA about the soil-the underground interchange tunnel group,analysed the underground interchange tunnel structure using the earthquake time history analysis.The results show that an increase in thickness of the lining will decrease the structural displacement and stress response,and increase the acceleration response,moreover,the influence degree is different.The results can be provided for the similar structure seismic design.
