| 摘 要： | 本文利用长期观测资料,提出识别地下水动态地震异常的原则和方法。在此基础上总结出唐山地震地下水动态异常场特征:空间上的象限性、时间上的阶段性、异常阶段的时空差异性及震时、震后异常变化的同步性等。并利用上述规律,探讨了震源应力场与区域应力场的依存关系和区分标志。最后,对微裂-过热水爆炸的冲击作用进行了探讨

THE CHARACTERISTICS OF FORERUNNER FIELD OF UNDERGROUND WATER REGIME DURING TANGSHAN EARTHQUAKE AND ITS FOCAL EVOLUTION PROCESS |
| |
| Abstract: | Basing upon the data obtained from long-term observations of ground water regime and taking the Tangshan earthquake as an example, the authors proposed first the principles and approaches to recognize the precursory anomalies of earthquakes and classified the subsurface water regime into underground water, interlayer water and confined water. For the Tangshan earthquake the forerunner field of underground water is characterized by its spatial distribution (limited to a certain quadrant), its sta |
