摘　　要：简要介绍了隧道结构的震害现象,总结了隧道结构的震害机理、震害的影响因素、地震反应计算方法中的反应位移法和隧道结构振动台试验等4个方面的研究进展。在对当前研究成果评述的基础上指出了当前研究中的一些问题,并对隧道结构抗震研究的重点问题进行了总结归纳,包括地震动输入的确定、结构抗震计算方法、特殊地质环境下隧道的动力特性、隧道结构地震破坏的准则与评价指标、隧道结构抗震反应分析模型、振动台试验的可靠性等。这些工作可以为从事这一领域研究和设计工作的有关人员提供一定的参考。On the basis of summarizing the existing earthquake disasters of tunnels, recent progress in some critical issues of tunnel structures were summarized in this paper, including four aspects ： earthquake damage mechanism, seismic damage influence factors, application of response displacement method to seismic response calculation of tunnel structures, as well as shaking table tests of tunnels structures. Based on these results, comments on existing research were made, then existing problems and some advice on this issue were pointed out, including ground mo- tion input mechanism, seismic design methods, tunnels dynamic behavior under special geological environment, seismic destruction criteria and evaluating indices, reasonable dynamic analysis model for tunnels, relability of shaking table tests. The works done in this paper may give a reference to persons engaged in research and design in this field.
