[摘要] 首先討論了盾構(gòu)隧道縱向地震響應(yīng)分析的響應(yīng)位移法中相關(guān)參數(shù)的不同確定方法，然后研究了一種將二維有限元?jiǎng)恿τ?jì)算與響應(yīng)位移法相結(jié)合的方法，這種方法能夠有效地模擬地震波在地基中的實(shí)際傳播過(guò)程，并且具有較高的計(jì)算效率。隨后利用這兩種方法研究了武漢長(zhǎng)江隧道工程盾構(gòu)段隧道的縱向抗震性能，并對(duì)計(jì)算結(jié)果進(jìn)行了對(duì)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.
Keywords: shield tunnel; two-dimensional dynamic finite element method; response displacement method; longitudinal seismic response analysis
