| 摘 要： | 中国大陆地震具有成组活动的特征，成组强震活动之间有增震和减震作用，本文应用构造块体成组孕育的理论模型讨论了成组强震活动间的相互影响及其物理机制，通过强震成组孕育，成组发生的理论模型分析了一次地震发生对其它震源区应力变化的影响，对前兆复杂性的影响，及此类模型在地震预报工作中的应用。把强震成组孕育和活动的模型应用到危险性分析和地震长期预报研究领域将对地震预报实践起到一定的指导意义。

| Abstract: | Earthquakes in China's continent are characterized by group occurrence. Theseismicity in different groups are mutually influenced. For example, earthquakes in oneseismic group can enhance or reduce the seismicity in another group. The interferenceamong group earthquakes and the mechanism of the interference are discussed in this paPerbased on a synthetic seismogenic model for group earthquakes in a tectonic block. The in-fluence of an earthquake on the stress variation in other source regions and on the varia-tions of precursors is analyzed by using the model. The application of the model toearthquake prediction is also mentioned. It is meaningful to use the model for groupearthquake preparation and occurrence in the field of risk analysis and long-termearthquake prediction. |
