摘　　要：新埕1地震观测井,是华北地区流量最大的自流热水井。该井的涌石现象与邻近地区的地震活动有较好的对应关系。分析认为,新埕1井水文地质条件特殊,其涌石活动主要是区域应力场变化影响造成的。观测分析新埕1井的涌石变化,对预报邻近地区的地震活动有重要的现实意义。The No.1 seismological observation well in Xinying is the largest artesian thermal-water well in North China. There is a better corresponding relation between the erupting stone phenomenon of this well and seismic activities in the adjacent areas. The analytic results show that the hydrogeologic condition in Xinying No.l well is particular its erupting stone activity is mainly caused by the effect of regional stress field variation. It is of important practical significance for predicting seismic activity in adjacent areas.
