摘　　要：以长江三峡工程诱发地震监测系统地下水动态监测井网2006年井水位的观测数据为研究对象,根据地下水正常动态特征及其影响因素,系统分析了2006年水库二期蓄水过程中相关测项资料的动态变化,发现库水位上升对三峡井网地下水动态有明显影响。On the basis of the observations of ground water level monitoring well network for the induced earthquakes in Three Gorges in 2006 and the normal dynamic characteristics and the influence factors of ground water, the dynamic changes of the relative observation items during second impoundment of the reservoir are analyzed. The results indicate that the effect of the impoundment on ground water dynamic is obvious.
