在类比地温梯度计算方法的基础上,将区域地下流压场中众多井孔的水位埋深归一化为每米井深或每百米井深的压力水头高度,即单位压力水头高度,定义为水头梯度值,并通过对水头梯度变差值时空强全方位扫描绘制出其动态演化图象,进而对未来强地震发生的潜在危险区进行预测。经唐山7.8 级强地震内符检验,效果较为理想 Based on the calculation method of analog geothermal gradient, the water level of many boreholes in the underground pressure field of the area is normalized to the pressure head height per meter depth or per 100 meters depth, which is the unit head height, which is defined as head The dynamic evolutionary images are obtained by scanning the spatio-temporal intensity of water head gradient variation in all directions, and then the potential hazard areas of strong earthquakes in the future are predicted. The Tangshan 7.8 earthquake within the character test, the effect is more satisfactory
