| 摘 要： | 利用1995年7月12日云南孟连Ms7.3地震和1996年2月3日云南丽江Ms7．0地震前保山井水位异常变化的原始资料，并根据介质体膨胀变化率和水位变化的耦合关系式，用有限差分法模拟了保山井水位的变化情况。通过拟合实际观测曲线，得出观测井附近含水层内平均应力变化率的演化情况。

| Abstract: | Based on the coupling relation between bulk dilatation ratio and water level variation,the water level variation of Baoshan well is simulated by using finite differential method.The original water level data is sampled during the preparation and occurrence of the Menglian M S7.3 earthquake on July 12,1995 and Lijiang M S7.0 earthquake on Feb.3,1996.The variations of the average stress rate near the well are obtained by fitting the simulated curves with practical measurement curves. |
