【摘要】 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,效果较为理想更多还原

【Abstract】 Based on the analogue to the calculation method of ground temperature gradient,the pressure water head height of one meter well depth or one hundred meter well depth,which are grouped from the water level buried depths of a lot of wells in regional ground fluid pressure fields,is defined as water head gradient value.By scaning the time,space and strength of difference values of water head gradient variation,the dynamic evolution image can be drawn and then the potential risk regions of future strong earthquakes can be predicted.The test result for the Tangshan M 7.8 earthquake is relatively ideal.更多还原
