通过对天津双桥井水位多年来的观测资料分析认为：（1）水位动态主要是受区域地下水开采的影响；（2）水位异常形态一律为上升型或突升型，不存在下降型；（3）异常时段只有短临异常，不存在长中期异常；（4）水位地震异常映震的震级与发震区地震活动的衰减或起伏有关，并非只反映中强以上的地震。
According to the observation data of Shuangqiao well water level in Tianjin over the years, it is concluded that: (1) the water level dynamic is mainly affected by the groundwater exploitation in the region; (2) the abnormal water level is all ascending or ascending, and there is no descending type; 3) There are only short-term and anomalous anomalies, and no long-term anomalies. (4) The magnitude of the earthquake anomaly is related to the attenuation or fluctuation of seismic activity in the seismogenic area, not just the earthquakes above mid-strong.
