水位随机气压效率的地震前兆异常研究
|
摘要
对在大气压力的随机气压变化作用下深井水位变化特点进行分析研究 ,在前人工作的基础上 ,提出可以利用大气压力的随机气压变化进行水位气压效率的计算。该方法较以往各种计算方法排除干扰能力强 ,计算方便 ,地震前兆异常突出 ,是水位气压效率地震前兆预报方法中能够应用于日常地震监测的方法之一。
The water level variation features in deep wells under the action of random barometric variation are analyzed and studied.Based on the studies made by our predecessors,it is presented that calculation of the barometric efficiency of water level can be made using the barometric variation.The method,as one of routine seismic monitoring methods in earthquake precursor prediction from water level barometric efficiency,is better to eliminate interference,easier to calculate and has clearer earthquake precursor anomaly than previous calculating methods.
