【摘要】 根据多台和达法,利用邯郸—邢台地区9个数字地震台的观测数据研究了该区波速比和泊松比分布特征。结果显示:(1)9个小区域波速比值在1.696～1.737之间,相关系数在0.988 3～0.999 1之间,研究区平均波速比值为1.719,平均泊松比值为0.244,所得泊松比值与研究区内地壳介质以花岗岩为主一致。(2)研究区内波速比和泊松比变化比较复杂,反映了区内上地壳介质性质的不同和地质构造的复杂性。更多还原

【Abstract】 According to multi-station Wadati diagram method,using the data from 9 digital seismic stations in Handan-Xingtai region of Hebei province,the distribution characteristics of wave velocity ratio and Poisson’s ratio values in this region are studied.The results show:(1) In 9 sub-regions,velocity ratio values are between 1.696~1.737,the correlation coefficients are among 0.988 3~0.999 1,the average velocity ratio value of the study area is 1.719,the average Poisson’s ratio is 0.244.The Poisson’s ratio result consistent with the crust medium which mainly consist of granite in the study area.(2) The wave velocity ratio values and d Poisson’s ratio values vary in complex image in the study area.It objectively reflect the different medium properties of the upper crust and the complicated nature of geological structure under the study area.更多还原
