摘　　要：将新版《中国地震动参数区划图》直接给出经验系数确定不同地震动下的峰值加速度方法、地震动峰值加速度的烈度转换方法、极值Ⅱ型分布拟合方法进行比较;并基于地震安全性评价报告给出的京沪高铁沿线十一个城市的地震动峰值加速度值,将该三种方法转换得到的结果,与安评报告中的数值进行对比分析。分析结果对于抗震设计中地震动峰值加速度的取值具有参考意义。A peak acceleration method of different seismic ground motion, a intensity converting method of seismic ground motion peak acceleration and a fitting method of extreme value were compared which were proposed by the new edition of ＂seismic ground motion parameters zonation map of china＂. The seismic ground motion peak acceleration value of eleven cities along the Beijing-Shanghai high-speed railway was obtained based on the seismic safety evaluation report, the values of the safety evaluation report was compared with those with three methods. The result could provide reference for the value of seismic ground motion peak acceleration of seismic design.
