【摘要】 速度结构模型对于地震定位、理论波形计算等具有重要意义。本文基于福建数字地震台网台站对2010年至2012年在福建地区进行的人工地震探测试验得到的震相数据,利用射线追踪原理,得到福建地区地壳一维速度结构模型,结晶层厚约为3.5 km,P波速度为5.47 km/s,上地壳厚度约为15.5 km,P波速度为6.09 km/s,下地壳厚度约为12.5 km,P波速度为6.78 km/s,莫霍面P波速度为8.07 km/s,地壳厚度约为31.5 km。将结果与其它研究结果对比,验证本文结果的可靠性。更多还原

【Abstract】 Velocity structure model is significant in earthquake location,synthetic waveforms calculation,and so on. In this paper,based on the analysis of the artificial earthquake phase data obtained from seismic network of Fujian from 2010 to 2012,the 1-D crust velocity structure model in Fujian region has been obtained by using the ray tracing principle. The model is about 31. 5km thick composed of three layers which are crystalline layer,upper crust,lower crust. The parameters of the model are H0= 3. 5 km,VP 0= 5. 47 km / s,H1= 15. 5 km,VP 1= 6. 09 km / s,H2= 12. 5 km,VP 2= 6. 78 km / s,VP n= 8. 07 km / s. Compared with other research results,it is shown the reliability of the results in this paper.更多还原
