[摘要] 首先讨论了盾构隧道纵向地震响应分析的响应位移法中相关参数的不同确定方法，然后研究了一种将二维有限元动力计算与响应位移法相结合的方法，这种方法能够有效地模拟地震波在地基中的实际传播过程，并且具有较高的计算效率。随后利用这两种方法研究了武汉长江隧道工程盾构段隧道的纵向抗震性能，并对计算结果进行了对比研究。

Abstract: After discussing the different computational methods of the relevant parameters in response displacement method, it researched another method oflongitudinal seismic response analysis of shield tunnel, which is a combination of two-dimensional dynamic finite element method and response displacement method and could simulate the seismic wave propagation in the soil effectively with high computational efficiency. Subsequently, the two methods mentioned above were applied to analyze the longitudinal seisnuc behavior of the shield section of Wuhan Changjiang Tunnel, with the respective results being compared.
