摘要: 根据人工地震与天然地震测深成果,提出了邢台地震孕育发生的概念模型。 根据这个模型,分析了邢台地震前震区应力分布图像与发展过程,结合深部构造特征,探讨了邢台地震的成核过程,进而讨论了邢台地震的直接前震、地形变、地下水位三项主要前兆的形成机制。

Abstract: Based on the results of artificial seismic exploration and natural seismic exploration, the model of preparatio and generation of Xingtai earthquake has been proposed. Accord mg to this model, the pattern of regional stress distribution and its development have been analyzed. Combined with characteristics of deep structure, the nucleation of Xingtai earth­quake and mechanism of its main precursors (direct foreshocks, deformation, underground water level) are discussed.

Key words: Seismic exploration, Xingtai earthquake, Pattern of regional stress distribution, Model of earthquake generation, Mechanism of earthquake precursors
