利用日本Kik-Net 85个台站的242组强震记录，将场地归类为01地震规范，计算了每个场地地下基岩和地表5%阻尼比的加速度反应谱，并根据地下基岩地震动输入的大小将场地划分为4个区间。研究了场地条件对每个场地地表加速度反应谱的影响，得出了短期内场地地震动放大最大的Ⅱ类场地、最小的Ⅰ类场地、仅次于Ⅲ类场地的最大反应谱。提出了各场地设计反应谱的场地系数最大值。
With the 242 group strong earthquake records of 85 stations at KIK-NET in Japan,the sites was classified as 01 seismic code,the acceleration response spectrum with 5% damping ratio of underground bedrock and surface at each site were calculated,and according to the size of the input ground motion of underground bedrock PGA was divided into four intervals.This article studied the effect of site condition on surface acceleration response spectrum at each site,and concluded Class Ⅱsite with the largest ground motion amplification in short period,ClassⅠwith the least,after Class Ⅲ site.The result shows the maximum response spectrum adjusted by site classification,proposes the maximum value of site coefficient of various sites design response spectrum.
