中文摘要：

针对不同埋深下隧道表现出不同震害的特点,对地震响应振动台模型试验进行研究。首先进行了试验方案设计及试验模型的相似比设计,然后对不同地震波类型、地震强度及不同埋深下的隧道依次进行了振动台模型试验。试验结果表明：地震作用下,隧道衬砌应力在隧道埋深较浅时最大,达到一定埋深（约40 m）时,隧道衬砌应力明显减小,之后,隧道衬砌应力随埋深的变化不明显;隧道衬砌应力随埋深的变化规律在不同的地震波类型、不同的地震加速度峰值下相似;不同深度土层的加速度放大系数随着埋深的减小逐渐增大。通过对试验后隧道周边土体观测可知,浅埋隧道周边土体的裂缝多于深埋隧道。试验验证了地震灾害调查结果,为隧道抗震设计提供依据。

英文摘要：

Considering that the tunnel diseases caused by earthquake are different in various depths, shaking table tests for seismic response of tunnels are conducted. Firstly, the programme and similarity ratios of the tests are designed according to similarity principles. And then, the shaking table test under different seismic waves, seismic intensities and depths are done. Test results show that the lining stress caused by earthquake is the largest in shallow buffed tunnel; When the buffed depth of the tunnel reaches about 40 m, the lining stress significantly declines, subsequently the lining stress remains relatively stable with the buffed depth. The relationships between lining stress caused by earthquake and tunnel depth are analogous for various kinds of earthquake waves and various acceleration peaks. The acceleration magnification factor increases with the depth of tunnel decreases. Meanwhile, the cracks in the surround soil around shallow tunnel are found to be more than those in the soil sound around deep tunnel. The research verifies the findings of earthquake disaster and will supply the reliable assurance for seismic design of tunnel.
