摘要
本文根据现场调查与大量搜集到的资料,简要地分析了大同—阳高地震的发震构造活动与区域应力场,并依此为基础探讨了地下水位动态异常场的形态组合、空间展布与时间演变等特征,提出了场内水位动态异常形态的多样性与以下降型异常为主,异常井空间展布的整体性与多层次结构,异常井随时间渐增的规律性与某些异常过程的转折,井点受力性质与水位异常形态间的某些关系等看法。
According to the on-the -spot investigation and a number of collected data, this paper briefly analyzed the seismogenic tectonic activity of Datong-Yanggao earthquake and the regional stress field. Based on this, this paper discussed the characteristics of form combination, spatiai distribution and temporal evolution of the anomalous field of groundwater level regime. Authors put forth some suggestions on the relation between the variety of anomaly forms of water level regime within the field, the entirety and multilevel structures of spatial distribution of anomalous wells with predominance of the drop-type anomaly, the gradual increase of anomalous wells with time, turning of some anomaly process, nature of the loading at the well sites and the anomaly forms of water level.
