| 摘 要： | 就山岭隧道而言,洞口段往往是震害最严重的部位。为了研究强震区隧道洞口段设置减震层的减震效果,对隧道结构进行了振动台模型试验。分别从衬砌的应变、加速度方面进行了分析,结果表明:减震层的减震作用明显。最后,对试验中的地表地震裂缝的震害进行了描述。

| Abstract: | As far as mountain tunnel is concerned,the portal part of tunnel is usually seen as the most serious part of earthquake damage.A shaking table test is done to study the effect of shock absorbing layer of the portal part of tunnel in strong ground motion zone.In this paper,the shock absorbing measures are analyzed from the aspects of the strain and acceleration of lining.The results show that the effect of shock absorbing layer is obvious.Last,the seismic damage phenomena of earthquake cracks on ground surface in the test are described. |
