| 摘 要： | 1997年1至4月，新疆维吾尔自治区伽师县境内发生了7次6级以上强震群。在此期间布设了由4个临时台站组成的地面加速度观测台网，共得到6级以上强震记录57条。本文给出这次强震群的烈度分布图和震源机制，研究了这批强震记录的相关谱特性及其与震源机制的关系。此外，还研究了这些地震的地震动与宏观烈度的对应关系以及地震动随震中距的衰减曲线。 |

| Abstract: | During January to April, 1997, there were seven earthquakes of magnitude greater than Ms 6 occurred in the Jiashi area of Xinjiang, China. Four accelerographs were set up in an array and 57 strong earthquakes were recorded. The intensity and focus mechanism of these earthquakes were described in this paper. Spectra of correlation functions for these records are analyzed. Finally, we discussed the relation of the ground motion with macro - intensity and the attenuation of ground motion versus the epicental distance. |
| Keywords: | strong ground motion characteristics earthquake intensity focus mechanism |
