| 摘 要： | 2014年云南景谷先后发生M_S6.6、M_S5.8和M_S5.9中强地震,云南强震动台网获取了丰富的加速度记录。本文整理了各次地震中固定台和流动台获取的强震动加速度记录资料,分别进行了地震动衰减关系和加速度反应谱分析,结果表明,所观测到的加速度峰值比云南地区地震动衰减关系预测值高,反应谱谱值随震级的增加有增大趋势。最后将益智强震台作为典型台站,分析了该台站在地震中的场地放大效应。

| Abstract: | In 2014, three strong earthquakes(MS6.6, MS5.8 and MS5.9) occurred in Jinggu, Yunnan Province. Numerous strong motion recordings were recorded by Yunnan Digital Strong Motion Network. In this paper, those acceleration recordings from both permanent and mobile stations are collected and processed, and the ground attenuation relationship and acceleration response spectrum are statistically analyzed. The results show that the observed peak accelerations are larger than predictions by Yunnan attenuation relationship in near and middle field, and the response spectrum increases with an increase in magnitude value. Finally, we take Yizhi strong motion station as a typical station to study its site effect during earthquakes. |
