中文摘要：

目前我国盾构隧道结构的抗震设计多采用地震系数法。文章引入反应位移法计算地震荷载作刚下的衬砌内力增量，对非地震荷载作用下的衬砌内力则考虑洞顶压力和孔隙水压力．将这两种内力叠加则得到隧道地震作用下的总内力，据此进行盾构隧道抗震设计；并与有限元法、地震系数法的计算结果进行了对比。结果表明，在进行盾构隧道抗震设计时，可以应用反应位移法进行衬砌的强度验算；在地震作用下，从竖轴开始隧道每隔30°将产生较大的正内力和负内力，在隧道横截面抗震设计中需要予以特别考虑。

英文摘要：

At present, the seismic coefficient method is often adopted in the aseismic design of most shield tunnels in China. In this paper, the response displacement method is introduced to calculate the increments of internal force in a lining under seismic loading, while the internal force in a lining under normal conditions is calculated by taking into account the crown pressure and the pore water pressure. Then, by means of the superposition of the above two kind of forces, the total internal force in the lining under seismic loading is obtained, and the aseismic design of a sifield tunnel is conducted based on all these factors. Compared with the calculation results of the finite element method and the seismic coefficient method, it shows that the response displacement method can be applied to the lining strength calculations for the aseismic design of shield tunnels and the major positive internal force and negative internal force would emerge evert 30° starting from the vertical axis under seismic loading, which requires special consideration in the aseismic design of a tunnel cross section.
