目前地下结构采用的减震措施主要有2种，即注浆加固和设置减震层。结合雅泸高速公路某隧道，从土-结构相互作用模型出发，运用时程分析方法研究同一地震作用下注浆加固及设置减震层这2种减震措施的地震反应，分析注浆加固范围变化对隧道地震反应的影响，得出这2种措施均可以减小隧道的地震响应，有利于减震。

At present, there are two major shock absorption measures for underground structures, i.e., grouting consolidation and shock absorption cushion. Taking a tunnel on Ya’anLuzhou highway as example, the authors study on the shock reducing effect of grouting consolidation and shock absorption cushion under the same earthquake action by means of soilstructure interaction model and timedependent analysis method. The authors also study on the influence of the changing of the grouting consolidation scope on the shock reducing effect. The authors conclude that both these two shockreducing measures are helpful to reduce the shock response of the tunnels.
