盾构隧道纵向地震响应简化动力有限元法分析(英文)
|
摘要
本文重点关注对盾构隧道的纵向地震响应分析方法的研究,提出了一种简化的动力有限元分析方法。这种方法采纳了响应位移法的一些基本思想,采用和响应位移法一样的环梁和土弹簧模型,但采用动力有限元法来评估地基地震动,而摒弃了响应位移法中采用的地基振动为谐波形式的假定。与响应位移法相比,简化动力有限元法能够提高地基震动的计算精度,从而提高结构响应的计算精度;而与三维连续模型相比,新方法的计算规模小得多,从而能够大幅提高计算效率。然后,本文分别采用相应位移法和新提出的简化动力有限元法,对武汉长江隧道盾构段隧道进行了纵向地震响应分析,并对这2种方法计算结果的差异进行了分析。
This article focuses on the approaches to the longitudinal seismic response analysis of shield tunnels,and presents a new simplified dynamic finite element method,which accepts some basic ideas of response displacement method.This method uses the same structure model and spring model as response displacement method,but uses the finite element method to estimate the responses of the ground in time series instead of the supposition of harmonic motion.This method could give more reasonable results compared with the response displacement method, because it could improve the precision of the evaluation of ground deformations.At the same time,this method has much smaller scale of calculation compared with the 3-D continuum model.Subsequently,both the response displacement method and the new simplified dynamic finite element method are applied to calculate the seimic responses of Wuhan Changjiang River Tunnel,with the emphasis on the difference of the results given by different methods.
