摘要
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 that: 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; and 2) the wave velocity ratio values and the Poisson’s ratio values vary in complex image in the study area.
