摘要
分析了南北地震带北段多年来应力场的动态变化特征,并结合其他前兆手段观测资料研究了应力场动态变化与地震活动的关系.探讨了应力场变化的动力成因和利用其进行地震预测的可能性.主题词:地应力场;动态变化;
The character of dynamic variation of stress field in north part of Chinese northsouth seismic belt is analysed, and comparing with data of some earthquake precursor observations, the relationship between the variation of stress field and seismicity is studied. At last the mechanism of the variation and the possibility of using it to protect earthquake are discussed.
