| 摘 要： | 以陕西省宝鸡市凤翔井为例,统计分析了2001-2006年降雨与地下水位之间的关系,发现"集中降雨"对浅井水位的影响较为明显,并在一定降雨量范围内呈指数关系.讨论了降雨通过荷载、进入断层面及改变地下水位埋深三个方面的作用改变了断层的有效应力,这种区域构造应力场的调整可能对区域中强地震活动具有触发作用.

| Abstract: | The relationship between rainfall and groundwater level is statistically analyzed from 2001 to 2006 at Fengxiang well in Baoji city of Shaanxi province.The result shows that Concentrated Rainfall obviously affect shallow well level and the both relate with a index within a definite confine.The influences of rainfall to effectively stress of fault are discussed in three ways such as rainfall loaded,filtering into fault surface and groundwater level altered.The effect to regional stress field can trigger moderate-strong earthquakes. |
