【摘要】 通过对新疆库尔勒台钻孔应变出现的阶变异常进行统计,将它和周边300 km范围内M S≥5.0地震对应,分析映震效果,又将阶变异常和辅助观测水位对比分析。分析结果表明,阶变异常一定程度上和水位关系密切,地震的前兆意义不明显。更多还原

【Abstract】 In this article,the stepping change abnormality of borehole strain in Korla station is studied. Firstly,the authors summarized and analyzed the earthquake reflecting ability of the stepping change before medium-strong earthquakes with M S≥5. 0 occurred nearby 300 km around the station.Through comparing the stepping change data with groundwater level data,it is shown that the stepping change abnormality was related with groundwater level in some way,not seismic precursor.更多还原
