摘要
本文分析总结了近年来我国地震工作者对岳阳市及其邻区(简称工作区)的地震地质及地震活动特征的研究。并在此基础上划定潜在震源区,估计各潜在震源区的地震活动性参数;利用工作区11次历史地震等震线资料,统计得到了工作区的烈度衰减关系,利用工作区的烈度衰减关系和美国西部烈度与地震动衰减关系转化得到了工作区的地震动衰减关系。最后计算得到了岳阳市相同概率水平的烈度、加速度、反应谱。
I In the Light of characteristics of seismic geology and seismic activities in Yueyang city and its vicinity investigated by Chinese earthquake workers in the last ten years, the author delineates the potential sources, and estimates the seismicity parameters of the potential sources. Using 11 historical isoseismals data of the studied area, the intensity attenuation law are obtained. Besides, the ground motion attenuation law for the studied area is obtained by using the intensity attenuation law of the studied area and the attenuation law of intensity and ground motion of the United States. At last, a risk-consistent response spectra with certain probability of exceedance for Yueyang city are presented.
