| 摘 要： | 根据１９９１年大同—阳高２次中强地震后的水准复测资料，分析了地震前后山西地区的垂直形变场。结果表明，该区垂直形变场震前显示出前兆形变，震后有明显的调整。定点形变分析证实太原台连通管、水平摆震前相继出现异常。大同台短水准震前数年观测到幅值不大的变化。震后，对这２个台继续进行跟踪，结果表明，再次出现新情况，显示出新的特点

| Abstract: | A analysis for the vertical deformation field in Shanxi region has been made based on the data of repetitive leveling after the 2 medium strong earthquakes at Datong-Yanggao in 1991. The result showed that the vertical deformation field before the earthquakes showed precursor deformation,and that after the earthquake regulated obviously .A analysis for the fixed point deformation evidenced that the anomalies of the connected pipe and the horizontal pendulum of Taiyuan station occurred successively before the earthquakes.The variation of the short range leveling of Datong station before the earthquakes is a few.The trace after the 2 earthquakes showed that new situation and feature occurred again. |
