六安地震台TJ-Ⅱ井下体应变观测与资料初析
Lu’an TJ-2 Borehole Strain Seismic Observation and Data Analysis
【摘要】 介绍了六安地震台TJ-Ⅱ体应变仪安装井的地质构造特点与井孔岩芯物理特性,以及TJ-Ⅱ体应变仪在六安地震台的运行情况。通过对六安台TJ-Ⅱ一年多来观测资料映震效应与区域前兆异常分析,初步分析了区域地下形变对大别山区未来中强地震预测研究的实际意义。
【Abstract】 The paper describes the geological structures and physical characters of rock cores of the well where the TJ-II strain Gauge is installed,and introduces the running conditions of TJ-II strain gauge in Liuan seismic station.Using the observed seismic events for more than one year,the paper analyzes the effects of regional varieties underground on mid-strong earthquake prediction in Dabieshan in the future.
