| 摘 要： | 本文在分析云南澜沧—耿马强震前地下水流量动态异常变化特征的基础上,对其形成的力学机制进行了探讨。得到的结论是,地下水流量对区域构造应力活动及地震活动具有非常灵敏的反映能力。其异常变化多出现在短临阶段,在时间上表现出集中性,在区域分布上表现出普遍性和不均一性,在表现形式上则具有多样性和复杂性。随着震中距的改变异常变化量显示出一定的规律。

| Abstract: | Based on the analysis of the anomalous characteristics of groundwater outflow before Lancang-Gengma strong earthquakes in Yunnan, the mechanical mechanism of the anomalies is discussed in this paper. We have obtained the following conclusions:the groundwater outflow has extremely sensitive reflection ability for tectonic stress and earthquake activities in a region. The anomalies of groundwater outflow mostly occurred during the short-term and impending earthquakes, and the concentricity of anomalous duration, the generality and heterogeneity of regional distribution, the complexity and diversity of anomalous variations are appeared as well. With the change of epicentral distance the anomalous variational quantity showed certain regularity. |
