| 摘 要： | 本文以强震记录为基础,通过土层地震反应计算得到了地表加速度与加速度反应谱,对比研究了由强震记录得到的地表加速度以及由地表加速度得到的与土层地震反应相同阻尼下的加速度反应谱.结果表明:在高频段与中频段,用一维等效线性化计算得到的土层地震反应加速度值与反应谱值比地表实测得到的加速度记录值与加速度反应谱值偏低；但在低频段,计...

| Abstract: | Based on the digital records of strong motion, we obtained the ground acceleration and acceleration response spectrum. By comparison between calculated soil seismic response to real records, we find that in the high frequency and intermediate frequency band, the value of soil calculated acceleration response spectrum is lower than the value of ground acceleration records from strong motion, but in low band, there are little difference between the calculated values and the recorded values. |
