摘要
20世纪 90年代中后期 ,攀枝花仁和钻孔应变台RZB - 1型压容应变仪记录了数次强震。通过计算该台的主应变方向 ,并结合强震进行分析 ,发现强震发生在该台的最大或最小主应变方向附近 ;计算了该台单位体积应变势能值 ,发现强震发生在应变势能值升至峰值后回落的过程中。这两种方法对于强震预测有重要意义。对于这些现象给出弹性力学解释 。
Several strong earthquakes' precursors have been recorded by Panzhihua city Renhe strain observatory during this earthquake actie episode The principal strain directions and strain potential energe values are calculated Analysed with strong earthquakes,the epicenters are located along the directions,and earthquake origin times are after strain potentialenerge dropping from maximum value A suitable explanation in elasticity mechanics is given This result will be meaningful to future earthquake prediction
