| 摘 要： | 2016年11月-2017年，徐州地震台YRY-4分量钻孔应变曲线出现"漏斗"状向下凹陷的压性变化，从场地环境、观测环境、观测系统进行现场核实，并对异常期间的观测数据进行对比分析，排除外界干扰及仪器自身问题，认为此次数据畸变可能反映了地下应力的真实变化，应为地下地质构造发生变化所致。

| Abstract: | The observation of the YRY-4 component borehole strain gauge at Xuzhou Seismic Station showed a downward funnel-shape compressive change. Through field verification of the site environment, observation environment, and observation system of the instrument and comparative analysis of the observation data, the outside interference and the instrument failure were excluded, and the data distortion may reflect the real change of underground stress. |
