摘要
该文描述了嘉山地震台TJ—Ⅱ体应变仪钻孔的地质构造特点与钻孔岩芯物理特性,介绍了TJ—II体应变仪在嘉山台运行情况。通过对嘉山地震台TJ—II型体应变仪近年来观测资料的分析,针对台站观测工作中遇到的漂移、突跳、阶跃、开阀、干扰等诸多实际问题,对各种现象作了较为系统的归纳总结。正确理解这些丰富的信息,对于今后工作中准确识别震前异常有着重要意义。
By analyzing TJ-2 type body strain meter observation data（from the initial installation to the normal work and recording to large strain seismic wave） of Jiashan Seismic Station, according to observation work in the practical problems encountered（drift, jump, seismic anomaly and interference）, for a variety of phenomena systematically induction. Correct understanding of these rich information, for the future work to accurately identify the earthquake anomaly is of great significance.
