摘要： 根据“局部构造上的凸起区, 水动态项目异常多表现为正异常, 而凹陷区则往往表现为负异常”的观点, 推断出双桥1、东台、天船等8口井震前的典型异常特征; 同时运用1989年至1999年发生在天津及邻近地区、首都圈及周边地区的多次中等、中强地震前天津地区水动态观测项目异常情况, 对推断结果进行了检验。证明检验结果与各井孔异常的实际情况相符, 由此得到天津地区地下水动态观测网中8口井水位、井压项目的典型异常特征, 对加强天津地区水动态项目异常的判定具有一定的实际意义。

Abstract: On the basis of the views that the anomalies are positive in upheaval area and are negative inde pression, the typical anomalous of 8 wells suchas Shuang qiao 1, Dontai Tianchuan wells and others before the earthquake arededuced. Using the anomalous data of waterdynamic state in Tianjin area before moderate and moderately strong earthquakes occurred in Tianjin and adjacent area as well as in Capital region and adjacent area from 1988 to 1999, thededuced results are tested. The result shows the situations of well's anomalies are consistent with thededucingresults. So the typical features of water level and well pressure of the 8 wells are obtained in Tianjin waterdynamic observation Network. It has a certain practical significance to streng thendetermination of anomalies of waterdynamic state in Tianjin area.
