摘　　要：地震荷载作用下,断层破碎带由于地质结构的脆弱性及不稳定性会致使地层产生永久变形,对于跨断层隧道结构造成显著影响,可能严重威胁人民生命财产安全,并导致灾难性后果。文章对跨断层隧道结构的动力响应和抗减震措施等问题,分析了国内外相关重要成果,包括隧道穿越断层的动力响应规律、隧道穿越断层的动力响应影响因素和隧道结构的抗减震措施;最后提出当前跨断层隧道动力响应及抗减震措施研究中亟待进一步探索的关键问题。Under the action of seismic load,the fragility and instability of the geological structure of the fault fracture zone will cause the stratum to be permanently deformed,which will have a significant impact on the cross-fault tunnel structure,which may seriously threaten people's lives and property,and lead to catastrophic consequences.the dynamic response and anti-seismic absorption measures of cross-fault,and analyzes and studies the relevant important achievements at home and abroad,mainly including the dynamic response law of tunnel crossing faults,the factors affecting the dynamic behavior of tunnels traversing fault lines,along with the seismic damping techniques employed in tunnel construction;Finally,Further research is required to explore the existing dynamic behavior and seismic mitigation strategies for tunnels that intersect fault zones.
