    Acceleration Peak Attenuation Relationship of Loess Region in Northwestern China on the Basis of Wenchuan Earthquake

      摘要
    • 摘要: 基于汶川地震期间大量地震加速度记录,利用直接拟合方法得到我国黄土地区土层加速度峰值衰减关系.借用美国西部相关研究成果,得到美国西部土层放大公式,并利用本文提出的修正方法对其进行最小方差的回归修正,得出我国西部黄土区土层放大公式,进而在少基岩加速度记录情况下,得到我国黄土地区基岩加速度峰值衰减关系.

       

      Abstract: Based on many seismic records of loess area in northwestern China during Wenchuan earthquake,a direct fitting method is used to obtain the soil site acceleration peak attenuation relationship of the loess area in northwestern China.The soil site acceleration amplification formula in loess area of western America is obtained on the basis of the relevant research results.With the revision method proposed in the paper,soil site acceleration amplification formula in loess area of western America is amend,and then the similar formula in loess area of northwestern Chin is obtained.Furthermore,the bedrock site acceleration peak attenuation relationship in loess area of northwestern China can be obtained although lacking of bedrock acceleration records.
