【摘要】 通过新疆及周边几次中强地震前克拉玛依钻孔倾斜表现出的异常特征分析发现,震前钻孔倾斜表现出的异常往往具有临震特征。根据对钻孔倾斜工作原理分析及中国大陆构造环境监测网络连续GPS最大剪应变的高值出现时间与钻孔倾斜异常出现时间具有部分重合现象,认为克拉玛依钻孔倾斜除了能反映地面倾斜意义之外,还具有反映剪应变的可能。更多还原

【Abstract】 According to analysis on characteristics of borehole inclinometer anomalies in Karamay before several moderate earthquakes in Xinjiang and its adjacent region,they found impending characteristics of borehole inclinometer anomalies before earthquakes.Through analysis on principle of borehole inclinometer and appearance time of maximum shear strain from GNSS and borehole anomaly coincide with each other,we hold that borehole inclinometer not only reflects gravity surface tide,but also reflects shear strain.更多还原
