摘要:
利用小湾电站水库诱发地震监测台网11个子台自2005年5月21日开始观测至2006年9月所记录的数字波形资料,在已知非弹性衰减系数和场地响应的条件下,用遗传算法反演了小湾水库近场328个中小地震的地震矩、应力降和拐角频率等震源参数,并对近场区及库区地震震源参数之间的关系进行了初步讨论。结果表明,小湾库区应力水平明显低于其周边区域。
Abstract:
On the basis of digital seismograms recorded at 11 stations of Xiaowan Reservoir Induced Earthquake Monitoring Network from 21 May,2005 to September 2006,we inverted source parameters near Xiaowan reservoir using genetic algorithm by the help of the known non-elasticity attenuation and site response and got source parameters such as seismic moment,stress drop and corner frequency of 328 earthquakes.We discussed the relation of source parameters in Xiaowan reservoir and its vicinity.The study shows that the stress level in Xiaowan reservoir region is clearly lower than that in the region near Xiaowan reservoir.
