| 摘 要： | 依据基岩场地上的汶川地震强震记录,分析了地震动地面峰值和核电站抗震标准反应谱的特性,证明了在推导和使用标准反应谱时所考虑的地面峰值加速度与地面峰值速度之比(PGA/PGV)受地面峰值加速度和震中距的影响,将对标准反应谱形状产生明显的影响.另外还发现了基岩场地的竖向峰值加速度可能要远比通常认为水平向峰值加速度的2/3大....

| Abstract: | Based on accelerograms on rock site from the Wenchuan earthquake,analyses of peak ground motion parameters and standard response spectra for nuclear power plant are made.The authors paid attention to the fact that the ratio(PGA/PGV)could be affected by PGA and epicenter distance,which is taken into account in developing standard response spectrum.This paper verified that such affection would significantly influence the shape of the deduced standard response spectrum.It is also validated that the vertical PG... |
