邯邢地区地壳直达波速度及地方走时表

CRUSTAL DIRECT WAVE VELOCITY AND LOCAL TRAVEL TIMETABLEIN HANDAN-XINGTAI AREA

摘要: 利用邯郸遥测地震台网1986年1月至1990年6月168个单台记录的34次邢台余震,计算出邯郸至邢台地区的地壳直达波速度分别为V_p=6.OOkm/s、V_s=3.53km/s、V_φ=8.62km/s,波速比V_p/V_s=1.699,并由此制定出适用于本区的地方走时表。结果表明,使用地方走时表较用J-B表处理的资料精度有较明显的提高。

Abstract: By using 34 Xingtai after shocks recorded at 168 single stations of Handan telemetered seismic network from January 1986 to June 1990, the crustal direct wave velocity for Handan-Xingtai area is respectively calculated as follows: V_p-=6.00km/s, V_s=3.53km/s,V_φ=8.62km/s, wave velocity ratio V_p/V_s=1.699.Based on this, the local travel timetable suitable to this area has been worked out.The result showed that the data precision processed by the local travel timetable was obviously higher than that by J-B table.
