Influence of bedrock depth on the seismic response of a nuclear reactor building foundation considering soil structure interaction

  • 摘要: 地震会对核电站安全造成影响。随着核电站的数量越来越多, 有必要关注在地震下核电站的安全。核反应堆厂房是核电站重要的组成部分, 研究其地震响应对核电站有着重要意义。基于直接法, 考虑了3种不同场地(中硬土、软岩、硬岩)在地震下的塑性变形和土的滞回阻尼, 使用FLAC3D对土-核反应堆厂房模型系统进行了三维建模。为了捕捉上部结构与下部岩石/土壤之间的分离与滑动, 在核反应堆厂房基础与岩石/土壤表面设置接触面单元。上层结构以集总质量模型模拟, 同时考虑土-结构相互作用下基岩深度对核反应堆厂房基础地震响应的影响, 最终得到核反应堆厂房结构杆件的加速度反应谱、剪力、基础的摇动和基础不均匀沉降以及侧向位移。结果表明: 在中硬土场地中, 位移、剪切力随基岩深度的增大而减小; 在硬岩场地中, 位移和剪切力响应的规律呈相反趋势; 在软岩场地中, 上部结构响应的规律较为复杂。对于基础摇动和基础不均匀沉降, 在中硬土场地中, 其呈现的规律随基岩深度增大而减小; 在软岩和硬岩场地中, 并无明显规律。基础不均匀沉降可直接反映结构的破坏情况。中硬土场地下基础不均匀沉降超过容许值, 所以基础不均匀沉降对核反应堆厂房的影响不容忽视, 这对核电站的安全设计十分重要。
