【摘要】 介绍了周至深井概况和水位高速采样技术系统的仪器设备配置。通过对该井2008年5月12日汶川8.0级大震及强余震的50Hz采样率水震波数字化记录进行分析,与同一台站的测震和强震动记录开展对比研究。结果表明,周至深井动水位对全球中强地震具有良好的观测效果,相当于一台深井宽带地震仪。更多还原

【Abstract】 General situations of the deep well and equipment configuration of the high speed sampling system of water level in Zhouzhi are introduced. We analyse digital records of the water level Oscillation of 50 Hz sampling rate of Zhouzhi deep well during the May 12, 2008 Wenchuan M8.0 earthquake and its strong aftershocks, and compare the the results with the seismic and strong motion records of the same station. The results indicate that hydrostatic water level of the Zhouzhi deep well has a good observation effect on moderate-strong earthquake in China,which is similar to that of a deep well broad band seismometer.更多还原
