地震台阵流动地震仪的检测与标定方法研究
Portable seismometer test and calibration used for the China Seismic Array
【摘要】 流动地震仪组成的台阵观测系统已经成为地下结构、物性探测的基本工具,高质量观测数据的获取是以地震仪的性能为基础的。本文结合中国地震科学探测台阵系统建设与维护实践,介绍了科学探测台阵系统采用的几项检测标定技术,包括超低频振动台标定、仪器一致性组网检测、白噪声标定和现场快速仪器检测,形成了一套适合地震流动台阵仪器的检测标定方法,并在观测实践中获得较好的应用。
【Abstract】 Seismic Array System, consists of portable seismometers, is becoming the basic tool for earth structure and physical properties detection.High quality recording data is basic requirement for the seismometer.During the construction and maintenance of the China Seismic Array System, we build up a set of guidance for portable seismometer testing and calibration, introduce several seismometers test and calibration techniques, including the super low-frequency shake table calibration, the instrument consistency test, the white noise calibration and the in-situ instrument fast test.We will introduce the practice and application in this paper.
【Key words】 seismic array; portable seismometers; seismometer check; seismometer calibration; instrument consistency; white noise;
