地震分析软件震相走时表文件结构研究
|
摘要
通过对现有地震分析软件所配置的震相走时表文件的结构类型及优劣进行分析,将震相走时表分为4种组合结构并分析其实用性。在IASPEI91震相走时表文件结构的基础上进行修改、补充和完善,从而提出了一种安全性高、适用面广、灵活性强、能存储各种结构走时表的新型走时表文件结构。应用这种新型结构震相走时表,地震分析软件可以灵活配置不同的走时表,实现精细定位,并为数字化测震台网快速利用测震资料编制和应用高精度的区域震相走时表创造了条件,对于地球深部构造研究具有一定的促进意义。
First of all,we analyzed file structure types of the seismic phase travel time tables of the existing seismic analysis software configuration and its advantages and disadvantages.In addition,we divided the phase travel time table into 4 kinds of composite structure and analyze its practicality.Thirdly,on the basis of modifying,supplementing and perfecting the structure of the IASPEI91 seismological table,we put forward a improved file structure of travel time table which is high safety,wide adaptation and strong flexibility,and can store travel time tables of different structures.Finally,by the application of the improved file structure of phase travel time table,seismic analysis software could be configured with different travel time table and realized the precise locating of the earthquakes.It created condition for the digital seismic network to use seismographic record for complication and apply regional seismological tables of high precision,have a certain meaning of studying the deep structure of earth.
