| 摘 要： | 介绍了盐源5．8级地震二滩大坝顶部的加速度时程及傅氏谱。由于该傅氏谱形态非常特异,为确认其正确性,特别从国内外数十条强震记录中归纳出了“加速度傅氏谱的基本结构为其时程疏密相间的‘节拍’所决定”的结论,并予以了数学解释。

| Abstract: | The acceleration process caused by Yuanyuan M5.8 Earthquake at the top of Ertan Reservoir Dam and its Fourier frequency spectra are analyzed.Since the status of the acceleration processes is special,we compare their Fourier frequency spectra with that of other acceleration data recorded in China and abroad in order to verify its correctness.The result of our analysis shows that the basic structure of Fourier frequency spectra of the acceleration process at the top dam is controlled by the rhythm phenomenon.We give out the mathematics explanations. |
