- 摘要:
- 针对测震台网台站方位角普查校正实际需要和方位角普查工作技术要求，提出测震台网台站方位标志安装、台站新安装地震计方位测定、已运行台站地震计方位角普查校正的操作方法以及摆墩与摆坑型场地地震仪输出极性的检测判定方法。
After analyzing the practical needs of azimuth correction and technical requirements of azimuth survey for seismic stations, this paper proposes the method for the installment of orientation signs in seismic stations. Then, this paper illustrates the method for orientation determination with newly installed seismograph and the operation approach to make correction in azimuth survey with long-term running seismograph. Besides, the detection method to determine polarity of the seismograph in a vault or on a pier is also discussed.
