通过利用实测钻孔应变资料的震时信息验证其可靠性是用钻孔应变资料进行地震分析预报必不可少的一项工作。本文对2003年9月26日日本8．0级地震昌平地震台的三种钻孔应变仪实测应变资料从各仪器的受力状况、应变阶跃等方面进行初步分析研究,以验证钻孔应变资料的可靠性。
It is an indispensable task to use the strain information of borehole strain data to verify the reliability of seismic data by using the information of earthquake time of borehole strain data. In this paper, three kinds of borehole strain gauges measured from the 8.0 magnitude earthquake of Japan on Sept. 26, 2003, were measured and analyzed from the strain and strain steps of various instruments to verify the strain of borehole Data reliability.
