利用地下水位的变化预报地震,国内外均已获得较好的效果。但是影响地下水位变化的因素较多,即使是能灵敏地反映地壳应力、应变变化的非人工开采层中的基岩承压水,除降雨、蒸发以及日、月吸力引起的固体潮汐应力等因素外,气压的影响也常常引起水位发生突变,如不注意分析,并加以定量排除,很容易误认为地
Prediction of earthquakes using changes in groundwater level has yielded good results both at home and abroad. However, there are many factors that affect the groundwater level change. Even the pressure water of bedrock in the non-artificial mining layer that can sensitively reflect crustal stress and strain varies with factors such as rainfall and evaporation, and the tidal stress caused by the monthly and monthly suction In addition, the influence of atmospheric pressure often causes a sudden change in water level. If we fail to pay attention to the analysis and quantitatively exclude it, it is easy to mistakenly believe that
