| 摘 要： | 本文运用动力时程反应分析方法，针对某百万千瓦级核电厂，利用FLAC3D对其取水隧洞进行了抗震分析，得到了其衬砌内力包络图。针对不同的设计方案，比较NNNN和马蹄形隧洞的优劣性。计算结果表明，圆形隧洞受力优于马蹄形，计算结果可为隧洞抗震分析提供依据。

| Abstract: | Aimming at the nuclear power plant structure and adopting time domain analysis approach, Seismic analysis of nuclear power project for intake tunnel is made with FLAC3D in this paper.The authors also protract envelope diagram of lining.Contraposing different design scheme, seismic behavior of circular tunnel and horseshoe tunnel are compared.It is shown that seismic behavior of circular tunnel is excellent than horseshoe tunnel.The regularity so obtained can provide the basis of the tunnel earthquake-proof analysis. |
