【摘要】 运用动力时程反应分析方法,针对百万千瓦级核电厂,利用FLAC3D对其取水隧洞进行了抗震分析。针对场地的岩质特征,对不同围岩下隧洞的内力分布开展具体研究分析,绘制衬砌内力包络图。计算得出的规律可为隧洞抗震分析提供依据。更多还原

【Abstract】 Aimming at the nuclear power plant structure and adopting time domain analysis approach,the seismic analysis of an intake tunnel for a nuclear power plant is performed with FLAC3D in this paper.Contraposing to the characters of the field rock of the nuclear power plant,the internal force distribution of tunnel under different wall rocks is researched and analysed,and envelope diagram of inner force in the lining of the tunnel is drawed.The regularity so obtained can provide the basis for the seismic response analysis and design of tunnels.更多还原
