摘要 结合地震活动性、气压及钻孔体应变观测资料,对首都圈地震活动与应变场变化关系进行了研究。结果表明:首都圈地震活动与测区钻孔体应变信息合成值的异常变化具有密切关系;地震活跃时间与体应变变化的时间同步;地震活跃区与体应变增强性异常变化分布区域一致。 The relationship between the seismic activity and the strain field change in the capital area is studied, by combining the data of seismic activity, atmospheric pressure and borehole body strain observation. The result shows that there is a close relation between the seismic activity and the anomalous change of the synthesized value of the borehole body strain information in the capital area, in particular,the time when the earthquakes are active and the time when the body strain is varying are synthronous and the area where the earthquakes are active and the area where the anomalous change of the body strain is increasingly distributed are in accordance with each other.
