【摘要】 通过对邯郸地震台网1984—2010年记录的当地及周边地震,计算当地的平均波速比及平均泊松比的值,对其间发生的M_L4.0以上地震分析,并对波速比曲线及地震震级曲线进行对比分析,得出该地区平均波速比为1.691,平均泊松比为0.229,震前波速比有低值,以期通过本研究能对当地波速比对地震的约束规律提供积参考。更多还原

【Abstract】 Using the data recorded by the seismic network of Handan for the local and surrounding earthquakes in 1984 to 2010,the mean wave velocity ratio and mean Poisson’s ration are calculated.Based on seismic analysis of earthquakes with M_L>4.0 and comparison analysis of wave velocity ration and the earthquake magnitude,it is obtained that the mean wave velocity ration in this area is 1.691,the mean Poisson’s ratio is 0.229 and the wave velocity ratio is lower before earthquake.The result of our research will provide useful reference for the constraint rule of the wave velocity ratio before earthquake.更多还原
