摘要

介绍了周至深井概况和仪器设备配置。通过对该井2004年12月26日印尼8．7级及2005 年3月29日8．5级两次强震的50 Hz采样率水震波数字化记录的频谱分析,与同一井孔的LN-3 数字水位仪及同一地震事件的周至台、西安台宽带数字地震仪记录进行对比研究。结果表明,周至深井各测项对印尼两次强震有明显的震时效应,观测效果相当于一台深井宽带地震仪。
The general situation and equipped instrument of Zhouzhi Deep Borehole are introduced. With spectrum analysis, the digital record of water-seismic wave of 50 Hz sampling rate of this well on magnitude 8.7 earthquake on 26 Dec. 2004 and magnitude 8. 5 earthquake on 29 March 2005, were analyzed. Comparing with the record of LN-3 digital limnograph of same well and record of broad band digital seismograph at Zhouzhi Seismic Station and at Xi' an Seismic Station of the same event. We obtained the result which shows that the Zhouzhi Deep Borehole has their obvious earthquake-time effect for two strong earthquake in Indonesia and observation effect is similar to that of a deep borehole broad band seismometer.
