However, topics and paper is rare about the attenuation of the peak ground displacement. The photos of the destructive buildings, bridges, pipeline show that the main cause was the difference between the two sides of the Cher-Lung-Pu fault.

• 国内外有关地震中地震动峰值加速度和峰值速度随断层距和震中距衰减方面的分析研究取得了较大的进展，而关于地震动位移(特别是地面永久位移)随断层距和震中距衰减的分析研究却并不多见，从许多震后现场建筑物和生命线工程的实际破坏情况来看，断层两侧巨大的位移差异是导致工程破坏的主要原因。
